DOWSIL™ PR-1205 Prime Coat - Enhances Adhesion for RTV Silicones

DOWSIL™ PR-1205 Prime Coat - Clear Primer for RTV and Heat-Cure Silicones

What is DOWSIL™ PR-1205 Prime Coat?
DOWSIL™ PR-1205 Prime Coat is a clear, high-performance primer designed to enhance the adhesion of RTV and heat-cure silicones to a wide range of materials, including metals, ceramics, glass, and plastics. It ensures durable bonding in demanding applications.

Applications

• Bonding to glass, metal, aluminum, FR-4, and ceramics.
• Enhancing adhesion for RTV and heat-cure silicones.
• Surface preparation for improved bonding reliability in PCB systems.

Benefits

• Significantly improves adhesion for challenging substrates.
• Easy application via wiping, dipping, or spraying.
• Dilutable for fine-tuned application control.
• Resistant to oxidation and weathering.

Features

• Compatible with a wide variety of surfaces.
• Facilitates durable and strong bonds.
• Moisture-curable at room temperature for convenient processing.

How to Use

DOWSIL™ PR-1205 Prime Coat should be applied in a light, even layer to cleaned surfaces. Abrasion or pre-treatment of surfaces enhances adhesion. Excess material should be removed to avoid a chalky residue. Allow a curing time of 1-2 hours under ambient conditions before applying the desired silicone elastomer.
