DOWSIL™ PR-2260 Silicone Prime Coat

Application:

• Apply in a very light, even coat by wiping, dipping or spraying
• Excess material should be wiped off to avoid overapplication
• Diluting by a factor of 2 to 4 with additional solvent may avoid excessive build-up

Dow primers, prime coats and adhesion promoters are dilute solutions of silane coupling agents and other active ingredients. The surface reactive components typically must be applied in a very thin layer for best bonding. The solvents used in these products serve to deliver the active ingredients in a thin, uniform coating, enhance surface cleaning, and in some cases, aid in the penetration of the active ingredients into the bonding surface.

Primers can be used to increase design flexibility, reduce total costs or increase performance reliability of PCB systems assemblies. They do this by enabling adhesion to lower-cost substrates or lower temperature processes which reduce energy budgets, among other possibilities.
