Dow Corning's line of conformal coatings includes three basic families:
-
RTV Elastomeric Coatings, the newest of these, are designed to provide fast
to very fast room temperature curing in a soft, stress-relieving material.
-
The next group, the RTV Elastoplastic Coatings, is either traditional or
ozone-safe solvent-based coatings that provide good abrasion resistance with
the expected good board protection.
-
The third group, the Solventless Heat Cure Coatings, is fast heat-curing
one-part coatings that again combine excellent protection in a soft,
stress-relieving material.
All conformal coatings contain a UV indicator enabling blacklight
visualization of the coating.
