DOWSIL™ 737 Sealant: High-Performance One-Part Silicone For Industrial Applications​

Product Attributes

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.

Core Characteristics

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.

Advanced Properties

Application Scenarios

Industrial Assembly: Replaces fasteners in appliances (refrigerator/freezer liners); automotive lamp sealing (VW TL 52006 certified).
Electronics: Waterproofing coaxial connectors (IP68), protecting instrumentation from condensation.
Construction: Bonding plastic moldings to substrates, outdoor display sealing (>10y weatherability per industry reports).
