DOWSIL PR-2260 PRIME COAT CLEAR RTV SILICONE

DOWSIL™ PR-2260 Prime Coat is a silane-based adhesion-promoting primer designed to enhance the bonding of RTV and heat-cure silicone materials to many metals, ceramics, and selected plastics. Supplied as a dilute solution of silane coupling agents and active ingredients dispersed in heptane, it is applied as a thin coating by wiping, dipping, or spraying before silicone application. The primer promotes improved adhesion while supporting greater design flexibility for electronics and industrial assemblies where reliable silicone bonding is required. :contentReference[oaicite:0]{index=0}
