Chemtronics Konform UR-A CTURA5 - Manual

PRODUCT DESCRIPTION
Konform® UR-A water-based urethane
conformal coating is designed to deliver
outstanding conformal coating protection using a
water-based carrier. It is engineered for
applications where durability and environmental
protection against moisture and air-borne
contaminants are required, while minimizing the
use and impact of VOC’s. This extremely
effective conformal coating provides protective
barrier against humidity, salt, corrosive vapors
and fungus for printed circuit board and
electronic assemblies. Coating meets IPC-CC-
830B Class B and sections of MIL-I-46058C,
Type UR.
