Description

IRS 2125 Flexible Epoxy Adhesive is a high performance black resin system. Its combination of flexibility and high adhesive strength lends itself to many high technology bonding, sealing and insulating applications. A two part system with a simple 1:1 mix ratio, it is supplied in a convenient side-by-side double syringe cartridge, complete with static mixing nozzles. Common applications include sealing electronic connections and elevated temperature bonding.

“It is nice to use because you don’t have to pre-mix it, and it has a convenient cure time. The tiles have been solid as a rock. It’s obviously the best!” – Carrie Reichardt, Artist
