About IRS 2112 Fast Curing General Purpose Epoxy Adhesive

IRS 2112 Fast Curing General Purpose Epoxy Adhesive is a popular, rapid curing, general purpose two-part epoxy adhesive. It has excellent adhesion to a wide variety of substrates, including metal, glass, composites, GRP, glass fibre, ceramic, ferrite, wood, rigid plastic and many other common substrates. It can be used for structural bonding and sealing.

IRS 2112 cures to handling strength in minutes (even in smaller mass applications), and typically reaches full cure in 6-12 hours. Mixed, it has a viscosity like syrup, and cures to a hard, glossy, almost-clear finish.

IRS 2112 is supplied in convenient side-by-side double syringe cartridges.
