2000 Series  Two part structural acrylic adhesive

Our 2000 series of adhesives are all two part adhesives with 1:1 and 10:1 ratios, meaning the adhesive and the activator are equal size.  Our 2000 series range from Structural Acrylic (Methyl Methacrylate), Reinforced Polyurethane or Epoxy resins.  The strongest of these adhesives would be the Methacrylate adhesive, high temp resistance, tensile and shear performance. Capable of filling gaps up to 10mm whilst maintaining it’s structural strength and characteristics and capable of going through a powder coat oven short term at 220°C. Open times vary from 1 – 40 minutes. Our strongest two part adhesive is our 2105 and also our biggest selling item. Polyurethane adhesives have low or no odour or shrinkage and are more environmentally friendly.  Epoxy resins are traditional yet still have have a unique quality as they are available clear and can be better at bonding some metals such as copper and brass with open times varying from 3 – 35 minutes.

Methacrylate adhesives are supplied in a two part system that when mixed offer a controlled cure speed suited to the application. The cured adhesive can offer incredibly high tensile, shear and peel strength, whilst also resisting impact loads at both elevated and sub zero temperatures.

Our UV identifiable primer for adhesives is an adhesion promoter for hard to bond substrates. When highlighted with an ultraviolet light, the exact location of the applied primer can be seen. This aids in accurate application of an adhesive or tape. This UV identifiable primer can be used on surfaces such as polyethylene, polypropylene, ABS, PET/PBT blends, concrete, wood, glass, metal and painted metal surfaces.

How to apply CTA’s UV identifiable primer for adhesives

• Apply a thin, uniform coating to the bonding surface with a brush or a swab, using the minimum amount that will fully coat the surface. This primer can also be applied with a pressurised flow gun, roller or other similar type of application equipment.
• Allow the primer to dry thoroughly before applying the tape or adhesive. This is usually accomplished in five minutes at room temperature.
• Ensure the primed surface remains free from contaminants prior to applying the tape or adhesive.
• Not that porous surfaces may require two applications of primer for a uniform coverage and good adhesion. Make sure that the first coat is dry before the second coat is applied.

See also our regular primer for adhesives.

After using the primer for adhesives, we also recommend using a micro lint free cloth with our IPA Cleaner degreaser to prepare a surface before bonding. This ensures that the surface is completely clean and free from dust, dirt and grease.

Purchasing primers for adhesives

Our UV identifiable primer for adhesives is available to purchase bottles of 236.5ml. A UV identifiable primer is also available. For other variations and quantities, please contact us. All prices are inclusive of VAT.

Types of Adhesives

HEAT-CURED ADHESIVES – Any adhesives which must be heated to promote curing.

HOLDING ADHESIVES – Holding adhesives are used to hold surfaces together, but not permanently.  They do not have to withstand a great deal of force.  Adhesive tape is a good example of a holding adhesive.

HOT MELT ADHESIVES – Hot Melt adhesives are applied in the molten state and then harden.  The adhesive substance is melted, applied to the surface, then the parts are joined. Once the adhesive cools and solidifies, the joint is complete.

INSTANT ADHESIVES – Any adhesive which cures within seconds to minutes, usually cyanoacrylates.

LOCKING ADHESIVES – Locking adhesives or sealants are used to prevent the loosening of threaded parts.  Locking adhesives are placed on the threads of a bolt to prevent is from becoming loose from vibration. Thread lockers and retainers.

PRESSURE SENSITIVE ADHESIVES  – Pressure sensitive adhesives form bonds easily when pressure is applied.  Pressure sensitive adhesives are used on double-sided tape.  The joint is aided with pressure.

RETAINING ADHESIVES – Retaining adhesives are used to prevent the twisting or sliding of non threaded parts.  retaining adhesives are very similar to locking adhesives except they are used on non-threaded parts.

SEALING ADHESIVES – Sealing adhesives are used to prevent the passage of air, water, oil, etc.  between two surfaces.  The caulking around windows is an example of a sealing adhesive.

STRUCTURAL ADHESIVES – Structural adhesives are capable of withstanding a significant load. The term ‘significant load’ has never been defined, but the implication is that the adhesive must be able to withstand a great deal of stress. In fact, it cold be said that in the absence of unnaturally high forces, the substrates could be considered to be permanently joined. see also structural adhesives in more detail with links to our products.

ULTRAVIOLET ADHESIVES – Any adhesives which cure when exposed to UV light.

 

Adhesive Terminology

An ADHEREND is a solid material in the adhesive joint other than the adhesive (sometimes referred to as substrate).  

ADHESION is the process by which two surfaces are held together by inter facial forces (surface attraction) or mechanical interlocking.  

An ADHESIVE is a substance which is capable of holding materials together in a useful fashion by means of surface attraction. Surface attraction results from placing a thin layer of adhesive between two objects.

The BOND LINE is the space or gap between two substrates which contains the adhesive.  

COHESIVE FAILURE is a failure mode where the failure is within the body of the adhesive, i.e. when adhesive is seen on both substrates in the same location.

COMPOSITE is a general term for an assembly of dissimilar materials used together to give greater strength than the individual components would on their own, or the same strength or lighter.  GRP (glass reinforced plastic) is an example of a modern day composite where resin and fibres are mixed together to give superior strength performance.  

CURE When an adhesive cures, it is converted from a liquid to a solid state.  This may be accomplished by cooling, loss of solvents or internal chemical reaction.  Curing generally implied some type of physical or chemical change in the adhesive, while hardening or melting is reversible.  

FIXTURE TIME is the interval of time between mixing a two part adhesive and the time a bonded assembly can be removed from the mould without distortion.  

RHEOLOGY is the ability of a material to flow and deform.  Adhesives with good rheology flow easily and break cleanly at the end of a bead.  

STIFFNESS is a materials ability to resist deformation when a load is applied.  

STRAIN is the elastic deformation resulting from stress.  

STRESS is he internal resistance to change in shape and size.  

A SUBSTRATE is a material, which is held by an adhesive.  Substrate is a generic term for objects that are being bonded.  

SUBSTRATE FAILURE is a failure where the substrate fails itself before the adhesive bond.  

TENSION is the stress resulting from pulling a material apart.  

A THERMOPLASTIC is a material that will soften when exposed to heat and can be reworked or re shaped before hardening when cooled.  

A THERMOSET is a material that solidifies when cured by mixing and/or heating and, once cured, cannot be remelted or remoulded.  

TOUGHNESS is a measure of a materials ability to absorb energy.  

VISCOSITY is the resistance to flow or degree of thickening of a fluid.  

WORKING TIME is the time between mixing the two components and when the adhesive becomes no longer usable i.e. skins over and will not ‘wet out’.  

WETTING is the intimate contact of a liquid and a surface.  Good wetting is only possible  if there is good attraction between the surface and the liquid.  Proper wetting of a mating surface is essential for good bonding.

Structural or performance adhesives are load-bearing adhesives.  That is they add strength to the products being bonded.  Structural Adhesives are used to build products as varied as office furniture, boats, trains, cars to name a few.  There are approximately ten adhesive families commonly referred to as structural adhesives: Methacrylate, Acrylic, Polyurethane, Epoxy, Anaerobic, Cyanoacrylate, Hot Melt, Solvent cement and Tapes.

The seven most commonly used are:

Acrylic adhesives have formulations that tolerate dirtier and less prepared surfaces generally associated with metals.  they challenge epoxies in shear strength, and offer flexible bonds with good peel and impact resistance.  Acrylics are two-part adhesives, the resin is applied to one surface and an accelerator or primer to the other.  The two parts can be pre-applied and later mated.  Once mated, handling strength is typically achieved in a few minutes.  Curing can be completed at room temperature.  Newer versions of acrylics are now available in two component formulations then are mixed together prior to application.  To discuss our acrylic adhesives please contact our technical team.

Methacrylate Adhesives provide a unique balance of high tensile, shear and peel strengths with the maximum resistance to shock, stress and impact across a wide temperature range.  Methacrylates can generally by used without surface preparation when joining plastics, metals and composites.  They are two component reactive materials based on methyl methacrylate monomer that, when mixed together, have a controlled cure speed based on the appropriate application process.  Methacrylates are tolerant to off ratio mixing and remain strong and durable under severe environmental conditions.  They resist water and solvents to form an impenetrable bond.  For CTA product information view following links: –

• Trial Kits Two Part Adhesives

Advantages – Moderately priced, good gap fill, excellent impact resistance and flexibility, excellent peel and sheer strengths, substrate versatility, medium/fast cure, tolerant of dirty surfaces, good flexibility at low temperatures.

Limitations – Some odour problems, flammable.

Polyurethane Adhesives are named after the polymer type formed on completion of the reaction.  the adhesives can be single or two component. With two component products one side is always isocyanate based, the other formulated from one of several core reactants often amines or glycols.  They are known for toughness and flexibility even at low temperatures.  They have fairly good shear strength and excellent water and humidity resistance, although uncured urethane’s are sensitive to moisture and temperature.

• Crusher Backing
• Polyurethane adhesive 12126
• Synthetic Grass Glue

Epoxy adhesives have been available longer than any engineering adhesive and are the most widely used structural adhesive. Epoxy adhesives are thermo-setting resins which solidify by polymerisation and once set, will soften but not melt on heating.  Two part resin/hardener systems will solidify on mixing (sometimes accelerated by heat), while one part materials require heat to initiate the reaction of a latent catalyst.  Epoxies offer very high shear strengths, and can be modified to meet a variety of bonding needs. Generally epoxy bonds are rigid: they fill small gaps well with little shrinkage.  For CTA product information view following links: –

• Toughened Epoxy Resin 2605
• Toughened Epoxy Resin 2620
• Toughened Epoxy Resin 2650

 Advantages – Usually low priced, good gap filling capabilities, high strength can be filled with metals, wide range of formulations, versatile, good temperature and solvent resistance.

Limitations – Adhesives thin during curing cycles, two component mixing and measuring required, exact proportions needed for optimal strength, single component usually required refrigeration and heat cure.

Anaerobic adhesives are one of the most easily applied structural adhesives.  Due to the curing mechanism being triggered by deprivation of oxygen (hence the name ‘anaerobic’ or ‘without air’), anaerobic adhesives will not cure prematurely.  these adhesives are based on acrylic polyester resins and are produced in viscosities ranging from thin liquids to viscous thixotropic pastes.  Although they have high cohesive strength, they have low adhesive strength and are not suited to permeable materials. Anaerobics do not fill gaps well and may require primers.  they are generally used as thread fasteners.  For CTA product information view following links: –

• High Strength Thread Locker 1227 Green
• High Strength Bolt Lock 1228 Red
• Thread Locker 1243 Blue
• Bearing Lock 1231
• Bearing Lock 1238 HT

Advantages – Moderately priced, high strength on some substrates, rapid cure at room temperature, good solvent and temperature resistance, versatile, range of viscosities, non toxic, no mixing required, dispenses easily from package, easily automated.

Limitations – Limited gap cure, not recommended for many plastic or rubber substrates, will not cure where air contacts adhesive – wet fillets, primers required for many materials, 150-200°C temperature limitations, generally brittle.

Cyanoacrylate adhesives (super glues) are also easily applied and offer extremely fast cure rates. Cyanoacrylates are relatively low viscosity fluids based on acrylic monomers and when placed between closely fitting surfaces, some will cure to a strong joint in ten to sixty seconds.  Cyanoacrylates’ ability to bond plastics and rubbers to themselves or to other substrates is their biggest advantage.  On the other hand, cyanoacrylate adhesives exhibit poor impact resistance, are vulnerable to moisture and solvents, and are suitable only for bonding small areas. In addition, they do not fill gaps well, require precise mating of bonded surfaces. They also have poor solvent and water resistance.  For CTA product information view following links: –

• Clear Rubber Toughened 12435
• Black Rubber Toughened 1135
• Cyanoacylate Gel 1154
• Bonding Kits (Mitre Mate) 1160
• Activator Spray 1191

Advantages – Rapid cure at room temperature, single component adhesive, excellent adhesion to rubber, good adhesion to metal, high tensile strength, no mixing required, indefinite pot life, dispense easily from package.

Limitations – Limited gap cure, low solvent resistance, low temperature resistance, bonds skin, poor impact and peel resistance, no water chemical or environmental resistance.

Hot Melt Adhesives have moved out of their traditional applications into areas of low-stress product assemblies.  They form flexible and rigid bonds, achieve 80% of their bond strength within seconds, bond permeable and impermeable materials, and usually require no elaborate surface preparation.  Hot Melts are insensitive to moisture and many solvents, but they soften at high temperatures.  To discuss our hot melt adhesive please contact our technical team.

Advantages – Moderately priced, good gap-filling capabilities, rigid to flexible bonds available, versatile formulations, fast setting.

Limitations – Usually low strength, poor wetting, poor creep resistance, usually low solvent resistance, low heat resistance – degrade as heat rises, stringy, parts must be mated before adhesive cools, short part life, messy can burn workers, requires special dispensing equipment, difficult to automate.
