920

920 is a one-part, gun grade urethane sealant/adhesive that moisture cures to an extremely tough, resilient seal which exhibits excellent tear and abrasion resistance while retaining permanent elastomeric properties. It has tenacious adhesion to most common marine substrates including virtually all woods, metal, FRP and most plastics. 

This product is recommended for any marine application above or below the water line where a quality elastomeric seal is required. It is suitable for sealing hardware around windows and doors, deck to hull assembly, hull seams, keel joints and under moldings.

However, 920 it is not designed as a glazing sealant in which the adhesive bond to glass is exposed to sunlight and appreciable amounts of ultraviolet radiation. 920 should NOT be used when the temperature is below 40° F.
