High-Strength Epoxies bond UV-blocking substrates.

Press Release Summary:

EMCAST V-150 and V-151 epoxy adhesive systems mate 2 UV-blocking substrates by pre-exposing epoxy adhesives to UV and visible light, then, after surfaces are mated, using room temperature or heat cure to solidify bond. EMCAST V-150 has 12,000 cps viscosity, 77 Rex D hardness, 4,400 psi tensile strength, and lap shear strength to 3,500 psi. EMCAST V-151 exhibits 15,000 cps viscosity, 82 Rex D hardness, 6,400 psi tensile strength, and lap shear strength to 3,800 psi.

Original Press Release:

New "Delayed Reaction" Epoxies

EMCAST V-150 and V-151 represent a new class of Delayed Reaction Epoxy adhesive systems. Two UV blocking substrates can be mated with high strength by pre-exposing the epoxy adhesive with UV and visible light. After the surfaces are mated, a room temperature or heat cure will solidify the bond. The delayed reaction feature makes this an excellent adhesive for colored plastics and some metals. These materials are a continuation of EMI's V-140 series Visible Cure Epoxy systems. They offer good shear strengths to plastics, particularly PVC as they are designed for laminating chips to "smart card" phone and credit card assemblies.
