PSI-601 is an excellent general-purpose RTV sealant. This moisture-curing sealant forms a durable, flexible, long-lasting rubber seal resistant to the effects of sunlight, rain, snow, ozone and ultraviolet radiation. It withstands temperature extremes higher than standard silicones and most other sealants.
PSI-601 has excellent adhesion to glass, metal, ceramic, porcelain, many plastics, and painted surfaces. PSI-601 FG is for food-area use. PSI-601 is not intended for structural applications.
PSI-613 is a one-part, RTV adhesive/sealant that withstands extreme temperatures. When exposed to atmospheric moisture, PSI-613 cures to a durable, resilient rubber with tenacious adhesion to most common substrates.
