ET538 Honeycomb Bonding Epoxy Adhesive

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.

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.

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; a 400ml cartridge would cover an area approximately 90cm by 90cm.

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.

The best use of this adhesive is to spread it in an even and thin layer over the panel you wish to bond the honeycomb to. You should aim for a layer no more than 0.5mm thick using plastic spreaders or similar to even-out the adhesive. Spread thinly like that, one 400ml tube should cover approximately 1 square meter. Press the honeycomb onto the adhesive and gently move it around very slightly to ensure the glue forms a slight fillet onto the honeycomb cell walls to get maximum bonding surface area.

The shelf life of ET538 is 12 months from date of manufacture.
