Surface primers generally improve adhesion strength by acting as a chemical
bridge between the substrate and the adhesive. Typically, the reactive species
in a primer will be multifunctional, with one set of reactive groups that will
preferentially react with the substrate surface, and additional groups that
have a high affinity for the adhesive.
Dow Corning primers are dilute (solvent-containing) solutions of silane
coupling agents and other active ingredients that:
-
Deliver the active ingredients in a thin, uniform coating
-
Enhance surface cleaning
-
Aid in the penetration of the active ingredients into the bonding
surface
Applying primer
-
Surface reactive components typically must be applied in a very thin layer
for best bonding.
-
Active components in primer react with atmospheric moisture. Recommended
conditions are room temperature and relative humidity of greater than 50%. Low
humidity and/or low temperature conditions require longer cure times.
