If you’re looking for a metal bonding glue, then we have lots to choose from. In short, it really depends on the application and what you are trying to bond together. We can bond most materials together though, using our very wide range of products and many years of experience.
Customers often search using the terms they are familiar with, and there’s a good chance you used one of them to get here too:
Metal to metal glue
Metal bonding glue
Glue for metal
GRP to metal glue
The list goes on of course, but all of our customers have a specific need… they want to join together two, sometimes more, similar or dissimilar items. You can’t use normal ‘glues’ to bond together GRP (Glass Fibre) and stainless steel for example, as they are just too diverse. They need an adhesive that has specific properties, allowing both materials to be correctly bonded together. Likewise, metal that becomes bonded to another metal may have to carry a weight or ‘load’ that would cause lesser glues and adhesives to simply come apart. Not too much of an issue for a picture frame bracket, but think of a high-stress bonded aviation, marine or automotive component and you’ll know why countless hours of research and testing have gone into developing our products.
How do I bond metal to metal?
Take a look at our two part structural adhesive here which is suitable for a very wide range of metal bonding applications. We even have trial kits for sale so the price is kept very low!
How do I bond GRP to metal?
Check out our GRP to metal adhesive here. You’ll also see that it’s odour-free and can be used to bond GRP, FRP, composites, metals, plastics and more.
What if I need more advice?
That’s fine, many of our clients came here with a bonding problem that needed solving or a specific problem using other products. We are very approachable and aim to solve any clients’ bonding requirements. Our blog shows some of the diverse applications that our products are used for and also details how we worked with clients to resolve their problems.
We also supply in quantities from small to extremely large, so if your project is anywhere from hobbyist to large multi-national then we can probably help!

These are caravan floor repair instructions for our CTA 2640 1.1kg kit. If parts of your caravan floor feel spongy or bouncy this can mean de-lamination. The caravan floor is made from polystyrene (also called styrofoam) that is sandwiched between plywood and the base. De-lamination often occurs near the door or in the kitchen area, with heavy use the polystyrene can become squashed which creates the spongy or bouncy feel.
The de-lamination kit, with the help of the dowels to reinforce the floor, will harden the floor and restore your caravan floor stopping the bounce.
• Easy to use.
• Make sure areas to be reinforced are clean and dry.
• Drill 8mm holes in the de-laminated section 250mm apart in a diamond pattern.
• Mix Part A and Part B together, until a smooth consistency is produced.
• Draw product into syringe and squeeze into the holes that have been filled ensure enough product into the cavity (when it protrudes from the holes).
• Tap in dowels, clamp/place weights on panel until dry, ideally 24 hours, then sand area to remove excess adhesive and protruding dowels.
• Replace the carpet or vinyl covering.
• Covers approximately 1 square metre.
Can you replace a rotten floor in a caravan?
While not every caravan floor is capable of being repaired, our kit can repair those cases where the laminate and polystyrene are still structurally sound, just separated from each other. The whole process can usually be done in a few hours plus a curing time of 24 hours, during which there should be no foot traffic or movement to the floor area. If the floor is completely rotten then it is unlikely to be repairable.
Why do caravan floors delaminate?
Caravan flooring typically has an upper plywood that you walk on, a mid layer of polystyrene and a base layer of external plywood. They are bonded together with an adhesive that reduces performance over time and is also weakened by moisture. This leads to separation of either two or all layers. We call this ‘delamination’ and our solution is to inject our powerful adhesive by syringe into the gaps, using the method above.

Crusher Backing resin compound for cone crushers is a 2 part polyurethane system used in cone crushers. It offers superb protection for the mantle and hopper.
Our CTA crusher backing resin is used as a shock absorbing compound that prolongs the life of the cone crushing machines. Quarrying and mining industries worldwide use our product as a cost saving flexible backing of low viscosity that flows into small cavities behind the manganese steel plates.
Also available with this product is our Crusher Backing Resin Release Agent. This is a wax based release agent which can be applied to the new mantle or hopper prior to pouring in the backing. This will allow the backing to be removed easily during the next service and manganese mantle change.
Why use CTA Crusher Backing Resin?
Easy application by machinery operators
Non-flammable means reduced transportation costs
Impact and shock resistance
Increased lifespan of equipment
Neatly packaged 10 kg kit
Part A is in a metal pail (8.33kg) and Part B is in a metal can (1.67kg).
Crusher Backing Resin Compound Kits
To ensure ease of application and reductions in transportation we decided to encompass the activator within the main tub of backing. This has been made possible by filling the activator into a foil bag, rather than traditional metal or plastic containers. Also reducing wastage and disposal of secondary container. The above images show how we have made this possible.
Advantages for purchasing from CTA Ltd
CTA are one of only a handful of suppliers who offer a NON-FLAMMABLE polyurethane as opposed to an epoxy resin. This results in reduced transportation costs for the customers and often a large reduction in paperwork and documentation required.

It is vitally important to ensure the maximum performance of the adhesive or tape is achieved, so we have put together this ‘best working practice’ for adhesive surface preparation.
It is always advisable to bond materials together in ambient temperatures i.e. between 15°C and 25°C . The first task before bonding your substrates is surface preparation, follow the guide below to ensure an optimum performance:
After selecting the correct adhesive, surface preparation is the most important thing you can do to achieve sufficient bond. This is because adhesives adhere to surfaces, and surfaces are often covered with dust, dirt, grease, oil, oxide films, rust inhibitors, and in the case of plastics, mould release agents. All these contaminants, even at a microscopic level, interfere with the adhesive doing its job. In fact, poor surface prep is the number one reason for bond failure.
For the strongest and most durable bonds, the goal is to apply adhesive to the substrate itself. However, often there are layers of surface contaminants that obstruct the surface. The ‘loose’ layer is all dust, dirt, and other loose particles. Beneath the loose layer lies surface oils and grease. Finally, there is sometimes an embedded layer clinging firmly to the surface such as rust, other oxide films, rust inhibitors, additives that have migrated to the surface such as mould release agents, and surface coatings like paint and sealants. All of the aforementioned prevent a strong bond, which is why surface preparation is so important.
Below are our recommendations for preparing surfaces for adhesive bonding. Please note that all manufactured materials vary significantly, even within the same type, as a result of different additives and methods used in the manufacturing process. This is especially true for plastics. Always test first on samples to determine suitability.
As a general rule, the more surface prep you do, the stronger and more durable a bond. Minimal surface prep, such as wiping the area clean, might be fine for simple bonds. For structural strength bonds, more treatment is required.
Here are the types of surface prep you can do, in order of greater effectiveness:
Clean the surface
1. Clean the surface
Prior to bonding all surfaces must be made clean and dry ready to apply your adhesive. Remove as many surface contaminants as possible from the bond area, including dust, dirt, and grease. For delicate surfaces, clean off as much as is practical, especially any loose particles or surface films. If you use detergents or liquids to clean the surface, make sure the surface is dry and void of trace cleaners before applying adhesive. Ideally use CTA IPA
The next step you can do is to degrease the surface. Degreasing removes all traces of oil and grease (even relatively clean surfaces have oils from fingerprints). If possible, use a solvent such as methyl ethyl ketone (MEK), acetone, or isopropyl alcohol CTA IPA. Wipe the surface clean in one direction. We recommend degreasing whenever possible, because surface oil or grease will get in the way of almost all adhesives and weaken adhesion (with the exception of methacrylates).
How to test if your surface is clean and degreased: For many surfaces, especially metals, a simple test to determine if your surface is clean and degreased is to drip a few drops of water on the cleaned area. If the water spreads to cover the area with a continuous film, the bond area is clean. If the water beads, that means the surface needs to be degreased further. Remember that all surfaces need to be dry before bonding. Also, bond the surfaces as soon as is practical after cleaning and degreasing to avoid having a re-contaminated surface. Also this test will not work well for certain plastics, because the water might bead, even though the surface is not clean enough for bonding.
CTA IPA Cleaner / Degreaser Kit
For the strongest and most durable bonds possible, we also recommend abrading. Abrading a surface gets rid of surface films, mill scale, paint, and oxides and also gives a much better area for the adhesive to “grip”. We only recommend abrading if practical for the material you are bonding. Use fine grain sand paper (120-200 grit), emery cloth, steel wool, or grit blasting. Abrade enough just to clean and roughen the surface. After an abrasion treatment, remember to remove all loose particles before applying adhesive. Brush the surface or blow with compressed air, and then degrease to clear away all loose particles and residual oils. Abrading and degreasing is enough surface preparation for all but the most demanding industrial applications.
4. Surface Alteration
Finally, some materials are simply difficult to bond. These include EPDM rubber, and “polyolefin” plastics (such as polyethylene, polypropylene, acetal, and hard nylon). Also, some metals such as copper, stainless steel, and aluminum are slightly more challenging to bond than other metals. If you are bonding these materials, you might need to change the surface properties or tension to get good adhesion. Specifically, these are considered low energy surfaces, and you need to alter the surface to increase the surface energy. This involves using chemical primers, scorching the surface, grit blasting, or acid etching the surface. Because all materials are slightly different, please call for advice or use our chat box to speak to an advisor. Always first determine if a solvent can be used without harming your material, especially in the case of plastics. Also, note that organic solvents are highly flammable. Follow all safety instructions and local regulations when using such solvents.
Surface preparation can be critical to achieving a satisfactory bond. Feel free to call our technical team to discuss any questions you may have.

The 6000 series of foamed acrylic adhesive tapes can be used with high surface energy (HSE) materials, such as aluminium, and low surface energy (LSE) materials, such as polyolefin plastics. The 6000 series consists of our strongest adhesive tapes, all with a distinctive red filmic liner.
5000 Series of Adhesive Tapes: Thick double-sided tapes
Our 5000 Series of tapes is a comprehensive range of quality foam-based adhesive tapes in a range of thicknesses and from high to low density. This range of adhesive tapes includes solvent acrylic, emulsion acrylic or hotmelt on both sides for each specific application. The strongest adhesive tapes in the 5000 series are our CTA 5175 tapes, with a solvent acrylic adhesive and which has a distinctive green filmic liner. The rest of our 5000 series of adhesive tapes have either white or amber liners.
NOTE: Some applications involve difficult to bond surfaces, where the need to increase the surface tension and the ability to bond a given surface is required. We strongly recommend our CTA Primer or our unique UV Primer as an addition to your application.
4000 Series of Adhesive Tapes: Thin double-sided tapes
Our 4000 series of adhesive tapes is our largest group of thin double-sided tapes and includes tissue, PVC, scrim and perm peel. Most have either a white or amber liner. Use our product selector guide to see which adhesive tapes suit your application needs or contact us for more information.

For any other variation or specific requirements please contact us.
NOTE: Preparation is the key to a great bond and maintaining that bond. Always ensure substrates are clean, free from dust, dirt or grease. Even handling substrates can transfer natural residues from your skin. Brand new substrates are not necessarily clean; they will have a residue and this can impact on the performance of your bond. We recommend using an isopropyl alcohol-based product (that evaporates) to clean surfaces before applying tape or adhesive. See our CTA IPA Cleaner Degreaser for more information.
3000 Series of Adhesive Tapes: Single-sided tapes
Our 3000 series of adhesive tapes are self explanatory and do what they say in their description. These adhesive tapes include single-sided tapes for different purposes.

Please use the following links to help with your adhesive selection:
Stress loads on adhesive joints can vary from application depending on the substrates being bonded and how pressure/force is loaded upon a joint. It is difficult to determine how differing stress loads on adhesive joints may affect the overall performance and durability of a bonded joint within an application. Various tests can be performed to ascertain each adhesives optimum performance and also what performance can be achieved when differing stresses are applied to a bonded joint. Stress is a force applied to a bond, usually expressed in N/mm² (Newton’s per square millimetre) or MPa (Mega Pascals).
Below you will see a variety of diagrams with an explanation about the stresses commonly found in adhesive bonds. One type of stress is Impact stress which occurs when a sudden force or shock is applied to a joint. for more information on joints view adhesive joint design.
Tensile stress: to pull an object apart. It also tends to elongate an object.
Compressive stress: the opposite of tensile stress, compressive stress tends to squeeze an object together.
Shear stress: created by two surfaces sliding over one another.
Cleavage stress: occurs when a joint is being opened at one end.
Peel stress: occurs when a flexible substrate is being lifted or peeled from the other substrate.
To speak with out technical team on any of the above contact us.
Adhesive joint design can vary tremendously dependent upon materials, dimensions and various limitations. This section has been put together to help determine and understand the numerous ways of bonding joints together and how this can benefit in strength and performance or adversely be detrimental to the overall performance and durability of the adhesive joint.
Their are many different attributes that need to be considered when metal bonding, these factors are types of joints, types of stresses and distribution of stress across the joint.
Types of joints
Please view the images on this page to assist in understanding popular joints. These images are cross sections of joints, grey signifies your chosen metal and blue signifies adhesive.
Double lap joint: Incorporates two lap shear joints in one.
Butt joint: Formed by bonding two objects end to end.
Joggle lap joint: Offset joint very similar to the lap joint.
Lap/Overlap joint: Formed by placing one substrate partially over another substrate.
Scarf joint: An angular butt joint. Cutting the joint at an angle increases the surface area.
Cylindrical joint: Uses a butt joint, to join two cylindrical objects.
Single or Double strap joint: A combination overlap joint with a butt joint.
Biscuit Lid Joint: a variation on a joggle lap joint
Flange Joint: A variation on an overlap joint
Toggle joint: Formed by fitting the two substrates together in a ‘tongue and groove’ type formation
Stepped lap joint: a variation of a lap shear joint
If you would like to discuss adhesive joint design further, please contact our technical team.
How much glue do I need? How much adhesive will I get out of a cartridge?
These are the most common questions asked of our technical team here at CTA. Below you will find a quick reference guide to the most popular cartridge and bulk formats used to dispense different adhesives. When dispensing or applying adhesives, you will most likely apply a linear bead. Depending on your application this could be differing greatly in volume and rate of delivery. We have calculated volumes and therefore lengths of the most commonly used beads per tube, cartridge or pail of adhesive. This will help you to answer the question “How much adhesive do I need?”
Bead length chart for CTA Adhesive products
Use the above chart to determine the approximate bead length for any CTA cartridge, tube or bulk application in comparison to the bead profile. To calculate the cost of adhesive per part produced, divide the cost per cartridge (or price per gallon for the bulk applications) by the appropriate bead length given above, and then multiply by the length of the bond line on the part.
