Features Of Dow DOWSIL PR-1204 RTV Prime Coat

  1. One-component, room-temperature vulcanizing (RTV) silicone primer requiring no mixing or catalyst.

  2. Excellent adhesion promotion to low-surface-energy substrates including polyolefins, fluoropolymers, and painted metals.

  3. Fast-drying formulation enables rapid handling and downstream processing—typically tack-free in under 30 minutes at 23°C/50% RH.

  4. Non-corrosive and halogen-free, supporting compliance with stringent automotive and electronics industry material requirements.

  5. Stable shelf life of 12 months when stored unopened at 5–25°C in original sealed container.

Typical Applications Of Dow DOWSIL PR-1204 RTV Prime Coat

  1. Priming plastic housings and bezels prior to silicone gasketing or bonding in automotive lighting assemblies.

  2. Surface preparation for silicone sealant application on polypropylene (PP) and thermoplastic olefin (TPO) exterior trim components.

  3. Enhancing bond durability between RTV silicones and powder-coated aluminum enclosures in industrial electronics enclosures.

  4. Pre-treatment step for silicone adhesive bonding on PTFE-lined fluid handling components in medical device manufacturing.
