Product Description
LORD P-1291 Primer is a low-viscosity, one-component adhesion primer for promoting bonds between tin-catalyzed RTV silicone rubbers and most metals or glass. It may also be used with some addition-cure silicone systems. The clear liquid can be brushed or sprayed onto properly cleaned surfaces, with a recommended 12 to 25 micron film and a 30 to 60 minute air-dry period before silicone application. Typical as-supplied values include 5 cP viscosity and 0.85 specific gravity at 25 deg C. The exact color variant of this generic primer requires confirmation.
Key features
- Low-viscosity brush or spray: The 5 cP clear liquid supports controlled primer application by brush or spray.
- Metal and glass adhesion promotion: Promotes bonding of tin-catalyzed RTV silicone rubber to most metals and glass in the supported applications.
- 30 to 60 minute air-dry: Provides a defined ambient drying step before the supported RTV silicone is applied.
Applications
Applications include promoting adhesion of tin-catalyzed RTV silicone rubbers to most metals and glass, with possible use in some addition-cure silicone systems.
