About IRS 2129-1 Rubber Modified Epoxy Adhesive
IRS 2129-1 Rubber Modified Epoxy Adhesive is a high performance black resin system. It is designed for the bonding of dissimilar materials, and is particularly suited to bonding rubber or bonding rubberised surfaces. The flow of the material has been modified to prevent ‘slump’ and cures to a semi-rigid finish, which is ideal to help prevent stresses in components and the bonding of materials in a dynamic environment. 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.
