DOWSIL™ 737 Sealant: High-Performance One-Part Silicone For Industrial Applications
DOW's DOWSIL™ 737 is a primerless, one-part neutral cure silicone sealant compliant with ASTM C920. It features rapid room-temperature curing (3-6 min skin time), extreme temperature resilience (-65℃ to 177℃), UV stability, and permanent elasticity from 100% silicone rubber formulation.
The oxime cure mechanism activates upon airborne moisture exposure to form flexible seals. Key advantages: direct adhesion to 20+ substrates (e.g. ABS, anodized Al, SS) without primers; zero slump/sag; rain resistance after 14-min tack-free time; handling strength in 24hrs. Limitations: Not FDA-approved for food contact; may discolor brass/copper and stress-craze polycarbonate in confined spaces.
