Product Information Primers Dow Corning PR-1200 RTV Prime Coat Red BENEFITS Enhances bonding/adhesion of RTV and heat cure silicones to many metals, ceramics, glass, masonry and plastics. Enhances adhesion of many moisture cure RTV and heat cure APPLICATION METHODS silicones Apply in a very light, even coat by wiping, dipping or spraying. Excess material should be wiped off to avoid overapplication. Diluting by a factor of 2 to 4 with additional solvent may avoid excessive build-up.
