Silbione® M&P Primer is designed to be applied to a clean dry surface.  The M&P Primer is applied by brushing, dipping, wiping, or spraying.  A thin film will give the best results.  Thickness can be controlled by thinning the solution in aromatic or aliphatic organic solvents. The primed substrate must be exposed to atmospheric moisture immediately after application for 30-60 minutes to induce evaporation of the solvent and to cure the primer.  Prolonged exposure greater than 2 hours will reduce effectiveness.  A minimum of 30% atmospheric relative humidity is recommended for full cure, and therefore, maximum adhesion to substrate. Air exposure of the primer should occur immediately after application to the clean surface to be primed.  If immediate exposure to air containing at least 30% relative humidity does not occur, the resulting primed film may result in poor adhesion to both the substrate and to subsequent silicone material added to the primed substrate.

SILBIONE M&P PRIMER may be stored for up to 12 months from its date of manufacturing.Please consult the Safety Data Sheet of this product.


Silbione® M&P Primer is a 10% active adhesion promoter dispersed in xylene that improves adhesion of silicone elastomers to some substrates such as metals, ceramics and plastics.
