WACKER® PRIMER G 791 A/B

Silicone Rubber Additives

WACKER® PRIMER G 791 A/B is a two-component, addition-curing primering system
diluted in an organic solvent. The primer is applied to the substrate and after curing forms a primer film 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.
