Momentive SilGrip PSA529 – High-Performance Silicone Contact Adhesive

Momentive’s SilGrip PSA529 is a high-performance silicone contact adhesive used in applications where other adhesives and bonding options tend to fail.

Applied using a brush or roller, it is an excellent candidate for use in laminating and assembly applications that require resistance to high temperatures. Maintaining flexibility and adhesion to difficult substrates under extremely harsh conditions is aided by the adhesive’s silicone backbone.

Use PSA529 as an alternative to Fasteners, Urethanes, Epoxies, Rubber cement and Spray Adhesives
