About IRS 2128 Toughened Epoxy Adhesive

IRS 2128 Toughened Epoxy Adhesive is a high performance black resin system. It has excellent adhesion to a wide variety of substrates and good chemical resistance. A two part system with a simple 1:2 mix ratio, it is supplied in a convenient side-by-side double syringe cartridge, complete with static mixing nozzles.

This adhesive is a good candidate to test for applications where there is vibration, impact or thermal shock. Its resiliency allows this adhesive to withstand impact and vibration stresses, absorb energy, and to deal with bonding materials with different CTEs under thermal cycling.
