Our range of Structural adhesives cover a multitude of assembly operations. They are avialable in cartridge or as bulk systems. Benefits over mechanical fastening methods include:
- No damage to substrates in assembly ( ie no holes need to be drilled or heat distortion if welding metal.
- Dissimilar materials can be joined without galvanic corrosion
- Fatigue resistance is increased as stresses are not concentrated in few localised areas
- No finishing steps are required offering improved aesthetics
Structural adhesives have the highest load bearing capabilities out of all other adhesive options and offer excellent chemical and environmental resistance. They are also available in a range of handling and cure times and do not require access to the air to dry, nor moisture and thus have an unlimited depth of cure

We categorise our structural adhesive range into Chemistry Types
Acrylics overall provide the highest bonding strength to plastics (including very hard to bond to materials such as polypropylene) and may also provide good bonds to metals including oily metals and powder coated surfaces The new generation of toughened acrylics also offer improved impact / vibration resistance.(Thus improved fatigue resistance),faster cure times and low odour.
Epoxies are available in a wide range of properties and can have the best overall properties on metals. Flexible epoxies have high peel strengths and also offer better impact resistance and are a good choice for parts which may flex in end use.
Toughened Epoxies provide the highest shear, peel ,impact, vibration and fatigue resistance and are therefore suitable for the most demanding applications
Polyurethanes tend to be the most flexible of all structural adhesives but have lower strength in general, but can be a cost effective solution for bonding plastics and rubber.
A general purpose, flexible two part epoxy adhesive with 8-13 minute work life and 20 minutes to handling strength at room temperature.
It has fantastic strength and stability under both states and dynamic loads and has a medium viscosity.
This adhesive is particularly good for boding dissimilar surfaces.
- Metals (both painted & unpainted)
- Many plastics HSE, MSE (ABS, Acrylic, Polycaronate, Nylon)
Also available in 400ml cartridges sizes.
An extremely tough and durable thixotropic, gap filling, two-part epoxy adhesive with outstanding environmental, impact and heat resistance (up to 120C).
Its non-sag properties makes it ideal for bonding vertical surfaces and its high sheer and peel strength makes it an ideal solution for critical applications.
It is also particularly good for the construction of composite materials and at bonding difficult surfaces such as powder coated materials and most plastics.
A transparent, non-yellowing and UV resistant two part polyurethane adhesive, ideal for applications requiring long term transparency.
DP610 is flexible, fast curing at room temperature (7 minutes) and forms a tough, impact resistance bond.
- Most plastics
- Primed or painted metals
