WACKER^® PRIMER G 790 is a solution of reactive siloxanes and silanes in an organic solvent. WACKER^® PRIMER G 790 TOLUENE FREE is free of toluene and free of other aromatic solvents. The primer composition can be applied to the substrate as such or diluted. During evaporation of the solvent and on exposure to atmospheric humidity at ambient temperature a rigid primer film is formed which firmly adheres to the substrate. Application of a silicone rubber onto the primed substrate and subsequent vulcanization will then result in a tight bond between the silicone rubber and the substrate.

Features:

• bonding agent preferably used with addition-curing silicone rubbers
• suitable for various coating techniques like dipping, brushing or spraying
• free of toluene and other aromatic solvents
