Kalrez® 4079 is a black, low compression set compound for use in many dry and wet semiconductor process environments. It has excellent chemical resistance, good mechanical properties and outstanding thermal stability. Kalrez® 4079 exhibits low weight loss in reactive plasmas and has good response to temperature cycling effects. It is not recommended for use in amines. A maximum continuous service temperature of 316°C is suggested. Short excursions to higher temperatures are also possible. Ultrapure post-cleaning and packaging is optional.
