Permabond UV7141 UV-curable Adhesive
Categories:	Polymer; Adhesive; Thermoset; Acrylic/Cyanoacrylate Adhesive
Material Notes:	Permabond UV7141 is a UV-curable adhesive with a secondary anaerobic cure mechanism. This makes it ideal for bonding materials such as ceramic-coated glass, mirrors, etc. where UV-light cannot penetrate to provide full cure in shadow areas. This dual cure mechanism helps speed up production rates. The UV cure tacks the components in place in seconds, reducing the need for jigging. The bulk of the adhesive then cures more slowly to produce optimum performance. Features & Benefits: Cures in shadow areas High shear strength Excellent environmental resistance 100% solids, no solvents Excellent adhesion to metal and glass Information provided by Permabond.
