WACKER® Primer G 790 Toluene Free is a solution of reactive siloxanes and silanes in an organic solvent. It is specifically formulated to be free of toluene and other aromatic solvents. The primer can be applied directly to the substrate or diluted if desired. As the solvent evaporates and when exposed to ambient humidity, the primer forms a rigid film that firmly adheres to the substrate. By applying a silicone rubber onto the primed substrate and subsequently vulcanizing it, a strong bond is achieved between the silicone rubber and the substrate.
