DOWSIL 1200

DOWSIL™ 1200 OS Primer is a one-part, air-drying adhesion primer supplied as a dilute solution of moisture-reactive materials in volatile siloxane. Applied before silicone bonding or sealing, it improves the quality and speed of adhesion development between room-temperature-vulcanizing silicone materials and a variety of common non-porous substrates. The primer is also suitable for use with heat-curing silicones and can be considered for ceramics, glass, wood, masonry, structural plastics including FR-4, and many metals. Substrate preparation, primer application, and compatibility should be verified for the intended silicone and surface combination.

Key features

• Air-drying, one-part formulation: Supplied ready for controlled application without component mixing.
• Silicone adhesion promotion: Supports faster and higher-quality adhesion development for moisture-curing RTV and heat-curing silicones.
• Broad documented substrate range: Applicable to ceramics, glass, wood, masonry, structural plastics including FR-4, and many metals.

Applications / Suitable for

• Priming common non-porous substrates before RTV silicone application
• Adhesion promotion for heat-curing silicone systems
• Silicone bonding and sealing on glass, ceramics, metals, masonry, wood, and supported structural plastics
