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. Application: Bonding agent preferably used for bonding addition curing silicone rubbers onto vulcanized, addition-curing rubbers (e.g. WACKER® ELASTOSIL® RTV-2, LSR and R plus or WACKER® POWERSIL® RTV-2 and LSR). WACKER® PRIMER G 791 A/B is especially suited for bonding addition-curing POWERSIL® XLR® 630/640 onto vulcanized silicone rubber of the same grade. Information provided by Wacker Chemie AG. |
