Aptek 2209-A/B Clear, non-yellowing urethane adhesive
Categories: Polymer; Adhesive; Thermoset; Polyurethane, TS; Thermoset Polyurethane, Adhesive

Material Notes: APTEK 2209-A/B is a water clear, thixotropic, two component, electrically insulating, urethane adhesive designed for bonding various substrates. APTEK 2209-A/B is effective for bonding plastics and in particular displays excellent adhesion to GE LEXAN (polycarbonate) without cracking or crazing the substrate.

Excellent U.V. and weathering resistance for outdoor application. Very good clarity for see-through applications like back-lit signs/displays. Convenient 1:1 PBW or PBV mix ratio for easy handling. Fast set version available upon request. Low viscosity, castable version available upon request.

APTEK 220-A is a clear polyol resin. APTEK 2209B is a clear organic isocyanate.
