Fast, UV Cure
Conformal Coating
- Cure in seconds
- Tack free
- Solvent free
- Rigid and flexible coatings
- Electrically insulating
- Environmental resistance
Description
DYMAX Conformal Coatings cure tack-free in seconds upon exposure to ultraviolet light. These 100% solvent-free conformal coatings can be applied over the entire surface of a printed circuit board or in discreet areas to provide complete protection from harsh environments.

Rigid and flexible coatings are electrically insulating, have high ionic purity and excellent environmental resistance. They exhibit low stress under thermal cycling and adhere well to flex circuit substrates. IPC, MIL Spec I-46058C and UL approved grades, multiple viscosities and ultra fluorescing and black grades are available.
