Many silicones are designed to adhere well to a wide variety
of substrates, but some silicone products and some surfaces
require adhesion enhancement to achieve adequate bond
strength. Surface treatments to improve adhesion can range
from simple cleaning to more complex etching, and may
require the application of reactive silane coupling agents to
achieve optimal bonding.
Dow Corning ® brand 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
of substrates, but some silicone products and some surfaces
