DCB

Modified Alkyd Conformal Coating (SCC3)

DCB is a flexible, black opaque version of DCA designed for the protection of electronic circuitry. It has been

formulated to meet the highest defence standards in both Europe and the United States.

 Black opaque coating; provides camouflage of PCB design

 Heat-cured coating is resistant to many solvents used within aerospace and automotive industries

 Suitable for use at temperature extremes; very wide operating temperature range

 Can be reworked using specialist removal product, Electrolube CCRG

Page 4 After the draining operation is complete, the boards should be placed in an air-circulating drying cabinet following the curing schedule highlighted on page 4. Brushing Ensure that the coating material has been agitated thoroughly and has been allowed to settle for at least 2 hours. The coating should be kept at ambient temperature. After the brushing operation is complete, the boards should be placed in an air-circulating drying cabinet following the curing schedule highlighted on page 4.
