Wacker Wacker® Primer G790
Categories:	Fluid
Material Notes:	WACKER® PRIMER G 790 is a solution of reactive siloxanes and silanes in an organic solvent. 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. Application: Bonding agent preferably used with addition-curing silicone rubbers like WACKER® ELASTOSIL® RTV-2 and LSR as well as WACKER® POWERSIL® RTV-2 and LSR. WACKER® PRIMER G 790 is especially suited for bonding addition-curing silicone rubbers to metallic and non-metallic substrates. Information provided by Wacker Chemie AG.
