PRODUCT DESCRIPTION
The Tru-Bond
TM
PSA 2500 Hig h Tack Pressure Sensitive Adhesive (PSA) is a one-part, solventless liquid that cures to a tacky
adhesive when exposed to UV/Visible light. This PSA can be cured directly through clear or translucent surfaces or cured
first prior to assembly. The curing first method allows for the joining of parts at some future point. This product can bond a
wide range of substrates including PE, PP, PET, TPU and most plastics, metals, glass, and ceramics. It can be sprayed, roll
coated, bead or brush applied, screen printed or used in a flexographic printing process.
