About IRS 2125 High Performance Flexible Epoxy Adhesive
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.
“The IRS2125 epoxy adhesive, performed beyond expectations when applied to seal high pressure hydraulic fluid in a plastic fitting which had sheared. The epoxy set extremely well and passed pressure tests such that it was deemed to be suitable as a permanent seal of the hydraulic system. I would recommend this product as it set rapidly to create an excellent seal and performed well, solving issue with leakage of hydraulic fluids.” – Ian Ross, GMX
