This product is well-suited for coupling Applied Liquid Silicone Rubbers, High Consistency Rubbers, and Adhesives to metals, fabrics, plastics, ceramics, and other substrates. Special features include:

•  Water consistency for easy handling 
•  Applicable by spraying, dipping, or brushing  
•  Requires no heating 
•  Improves silicone elastomer bonds to most substrates 

The surface to be primed should be thoroughly cleaned and allowed to dry. The primer is then 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 thirty to sixty minutes to induce evaporation of the solvent and to cure  the silane coupling agents.  Prolonged exposure greater than two hours will reduce effectiveness. A minimum of thirty percenty 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 thirty percent 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. 
 

A Material Safety Data Sheet (MSDS) is supplied with each shipment. The primer hydrolyzes quickly upon contact with atmospheric moisture.  Keep in tightly sealed containers and avoid exposing surface of unused material to ambient air. Purging containers with dry nitrogen before resealing is recommended. The dispersion contains the solvent xylene which is a flammable liquid and a health hazard. The dispersion should not come into contact with eyes, skin, or clothing.  Do not breathe the vapor.  Use the dispersion with adequate ventilation. Keep away from open flame, sources of sparks, and heat. When transferring dispersion, electrically ground all vessels. The user is urged to be familiar with the properties of xylene.
 

Packaging is available in 1-pint, 1-gallon and 5-gallon cans and in 55-gallon drums. 

The solution is a flammable liquid and must be stored and transported in accordance with applicable Federal, State, and Local regulations. Store in the original sealed container below 30ºC.

Suggested retest date is twelve months from date of shipment. 

Each production lot is certified as having specified physical properties. Other testing is available upon request.
