DOW CLEAR PRIMER COATING RTV 309GM PR1200-10-90ZCL

DOW® Clear Primer Coating RTV 309 gm PR1200-10-90ZCL (DOWSIL™ PR-1200) is a single-component, naphtha-based silane coupling agent formulation that functions as a clear adhesion promoter for RTV and heat-cure silicone systems, significantly enhancing chemical and mechanical bonding to substrates such as aluminum, titanium, stainless steel, glass, ceramics, composites, structural plastics, and glass-reinforced epoxies. It establishes a durable molecular bridge between low-energy surfaces and silicones, improving peel strength, reducing delamination, and preserving bond integrity under cyclic thermal loads, moisture, UV exposure and aggressive aviation fluids. Optimized for aerospace sealing, gasketing, sensor encapsulation, structural joints and fairing interfaces, DOW® PR1200 cures rapidly to a low-viscosity film, enabling precise 309 g cartridge dosing while maintaining stability in extreme environmental conditions.
