FluoroPel 420-F25M is a fluoroacrylic copolymer solution in a fluorosolvent for coating circuit board components to prevent corrosion, tin-whiskers and dendrites. Films dry in a few minutes at room temperature and provide a surface with a contact angle to water of approximately 100°. This may be used as a Parylene replacement. Please contact Cytonix for custom formulations with different solvents and functional properties.
