Tru-BondTM PSA 4500 is a one-part, solventless PSA (pressure sensitive adhesives) that cures to a tacky adhesive when exposed to UV/Visible light. This adhesive 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, 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.
