PORCELAIN PRIMER

BISCO’s PORCELAIN PRIMER is a single component silane coupling agent in an alcohol and acetone base that is used to improve the adhesive bond between porcelain and composite.

Silane is a dual function monomer consisting of a silanol group that reacts with the porcelain surface, and a methacrylate group that co-polymerizes with the resin matrix of the composite. Silane coupling agents are known to enhance the wettability of glass substrates by composite resins, increase physical, mechanical and chemical bonding of composite to porcelain, and yield a greater resistance to water attack at the bonding interface.
