ET500 Structural Epoxy Adhesive

28.76 (ex vat)

ET500 is a fast curing, clear, rigid two-part engineering grade epoxy structural adhesive. ET500 has very good bond strength to a wide variety of substrates including metals, composites, wood, ceramics and some plastics.

5min cure. Supplied in a twin cartridge pack (1:1 ratio, resin and hardener).


ET500 Epoxy Adhesive is a very high performance, 5 minute structural adhesive suitable for a wide range of demanding bonding applications.

Permabond‘s ET500 is a fully rigid epoxy glue with a 5 minute 1st-stage cure making it ideally suited to applications where a fast cure and strong, rigid bond are required. Full bond strength is not reached for 24hrs.

Structural fast epoxy adhesives are our recommended adhesives for bonding metal (aluminium, steel, titanium etc.) to other metals and to plastics (carbon fibre composites, fibreglass/FRP/GRP). Although epoxy adhesives are also suitable for plastic-to-plastic bonding, in many instances an acrylic adhesive adhesive will outperform epoxy adhesive for plastic-to-plastic applications, such as GRP to GRP or CFRP to CFRP.

Pack Sizes and Dispensing

ET500 Epoxy Adhesive is a professional adhesive and is therefore sold in the standard 50ml Twin Tube pack which requires the standard type 50ml Twin Tube Dispenser Gun, available to buy separately. The adhesive is supplied with 1x Static Mixer Nozzle.

Can you store this product if you don't use it all in one go?

Yes, certainly. In fact the easiest way to do this is to simply leave the static mixer nozzle in place after you use the adhesive. The adhesive that's in the nozzle will have been mixed and so will cure but the glue at the start of the nozzle will be unmixed and not cured meaning the nozzle will twist off perfectly and the glue inside will have been protected from the atmosphere and so will be perfectly preserved ready for use.

What sort of coverage would you get from a twin tube cartridge?

A typical application of the adhesive is approximately a 0.5mm thick layer. At this thickness, one 50ml cartridge would cover an area 30cm by 30cm. 

For best results when gluing over a large surface area, use a spreader to help ensure the adhesive is laid down in an even layer.

Is there a minimum gap fill?

There is no practical minimum bond thickness for this adhesive although you do need to ensure that *some* adhesive is present, which is why glass spheres are sometimes used to prevent the adhesive from being scraped off completely. Essentially though, as long as an even thin film is applied the bond strength between the two materials will be good.

Can ET500 be pigmented?

Yes ET500 can be pigmented. We have a range of  Epoxy Colour Pigments that will work well. Alternatively, for transparent tints try our range of  Translucent Tinting Pigments.

Is this adhesive drillable once cured?

Yes. Once fully hardened, the ET500 adhesive can, like most cured epoxies, be drilled. You would typically use a metal cutting HSS drill bit and starting with a small pilot hole, work your way up to the bigger hole sizes. Be careful not to use too much speed or pressure to avoid the resin being damaged by heat.
