Permabond UV645 UV-curable Adhesive
Categories:	Polymer; Adhesive; Thermoset; Acrylic/Cyanoacrylate Adhesive
Material Notes:	PERMABOND UV645 is a single part, fast curing, high viscosity UV curable adhesive designed specifically for bonding plastics. This material has excellent adhesion to a variety of plastics including polycarbonate as well as metals and glass. Permabond UV645 has very high shear strength, elongation and impact resistance making it ideal for applications that require substrates with different coefficients of thermal expansion. Permabond UV645 has good depth of curing capabilities which make it suitable for use as a sealant. Protect liquid adhesive from room lighting. Features & Benefits: Cure on demand High shear strength Fast curing with low-power lamps 100% solids, no solvents Excellent adhesion to plastics Information provided by Permabond.
