Fast, UV Cure Conformal Coatings
Dymax UV Cure Conformal Coatings cure tack free in seconds upon exposure to UV/visible light to help streamline manufacturing assembly processes. Apply, cure, and ship immediately and eliminate the time-consuming steps of traditional thermal-cure and room temperature-cure conformal coatings. 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. Dymax conformal coatings are available for tin whisker mitigation, humid environments, and shadowed areas.
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. Flexible coating for medical electronics passes ISO 10993 testing.
Solvent-free conformal coatings contain low VOCs, eliminating the need for solvent handling, while enhancing worker safety and minimising environmental impact. Each conformal coating is one part (no mixing required) for easy dispensing.
