Which Adhesive do I need?

Which Adhesive do I need?  A common question when determining which product to bond substrates together successfully.  This part of our website including it’s links are an informative guide to assist you in your quest for the right adhesive, giving a basic knowledge and understanding of common terminology used in the industry.

Stress loads on adhesive joints

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

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.Compressive Stress



Shear stress:  created by two surfaces sliding over one another.

Shear Stress




Cleavage stress:  occurs when a joint is being opened at one end.Cleavage Stress





Peel stress:  occurs when a flexible substrate is being lifted or peeled from the other substrate.

Peel Stress

Adhesive joint design

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

Double lap joint:   Incorporates two lap shear joints in one.

Butt joint:   Formed by bonding two objects end to end.

Lap/Overlap joint:   Formed by placing one substrate partially over another substrate. Lap Overlap Joint

Scarf joint:   An angular butt joint.  Cutting the joint at an angle increases the surface area.Scarf Joint

Cylindrical joint:   Uses a butt joint, to join two cylindrical objects.Cylindrical Joint


Single or Double strap joint:   A combination overlap joint with a butt joint.

How much adhesive do I need?



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.

Crusher Backing resin compound for cone crushers

Crusher backing compound

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.

CTA Crusher backing resin compound is shipped globally and we now have a base in the USA!

Why use CTA Crusher Backing Resin?

Crusher Backing Packaging.

  • Easy application by machinery operators
  • Non-flammable means reduced transportation costs
  • Impact and shock resistance
  • Increased lifespan of equipment
  • Labour saving
  • Neatly packaged in a single tub with the activator self contained in a foil bag.

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.

Metal to metal Application

There are many different situations where an adhesive or tape can bond metals together.  Typical applications would be aluminium panel pre or post powder coated, Aluminium and steel fabrication where it is difficult or not required to rivet or weld. This method is also advantageous when you need to bond dissimilar materials i.e bonding plastic panels to metal or acrylic sheets to di-bond.
