DOWSIL™ PR-1200 RTV Prime Coat RED

Red primer for silicones

General purpose kerosene-based primer for use with all silicone elastomers and RTV. It also improves the adhesion of some one-component silicone sealants and coatings to various building materials such as plywood, masonry and metal.

Application Applications

  • Clear general purpose kerosene based primer for use with all silicone elastomers and RTV.
  • improves the bonding/adhesion of silicones to many materials:
    • Metals
    • Ceramics
    • Glasses
    • Stone
    • Plastics

Features and Benefits

  • Increases the adhesion of many moisture-cured and heat-cured RTV silicones
  • increases flexibility and reduces design costs
  • increases the operational reliability of PCB assemblies

How to use

  • Apply a very light, even layer by wiping, dipping or spraying.
  • Excess material should be wiped off to avoid overapplication.
  • Diluting 2 to 4 times with additional solvent may prevent excessive buildup

Surface preparation

The active ingredients must thoroughly moisten and cover the surfaces to be bonded. Surfaces should be cleaned and/or degreased with kerosene, white spirit, methyl ethyl ketone (MEK) or other suitable solvents. Allow solvents to evaporate completely before applying primer.


These products require airborne moisture to cure and typically cure at a room temperature and relative humidity range of 20 to 90 percent for 1 to 2 hours. Low humidity and/or low temperature require longer curing time. Light heating increases cure rates, but temperatures above 60°C (140°F) are not recommended.

Once the primer has been primed and hardened, apply the desired silicone elastomer
