PLASMAtech’s plasma enhanced chemical vapor deposition (PECVD) coating technology provides a “green” alternative for bonding or over-molding metal components.
Surface preparation of metal
components prior to bonding incompatible materials may require caustic chemical
etchants or other costly conversion coatings to ensure good bonding to the base
metal substrate. By depositing a thin polymerized coating it is possible to
create a tie or interface layer that permits direct bonding or over-molding to
the metal surface. The resultant bond performance is excellent with results
that often surpass those achieved with conventional methods.
Superior to other coating or
conversion processes, plasma polymerized thin films can be deposited directly
onto a plasma pre-cleaned substrate without exposure to the atmosphere. This
continuous multi-step process provides excellent adhesion to the base substrate
with the polymerization occurring at an atomic level.
PLASMAtech provides contract
processing services, as well as a full line of low-pressure gas plasma and
parylene coating equipment. Process development services are available for
unique or especially challenging surface engineering requirements.
