Description
EL-O-MATIC CSR-actuators have an excellent corrosion resistance in environments where the actuator is
in contact with chemicals like caustic soda. The CSR coating itself is resistant to at least 1000 hours of salt
spray test exposure. Together with the excellent mechanical properties, the CSR coating is "the" solution for
very harsh environments.
CSR actuator housing and caps are completely coated (inside and out) with a ceramic filled fluoropolymer
based epoxy resin, impregnated by a temperature of 240°C into the aluminum surface.
Approximately 40% of the coating is impregnated into the aluminum, 60% stays on the surface of the
component as a seal.
