Master Bond Polymer System EP30M3FR is a low viscosity, two-component flame retardant epoxy compound for high performance, chemical resistant casting and potting applications, formulated to cure at ambient temperatures or more rapidly at elevated temperatures, with a convenient two (2) to one (1) mix ratio and meets UL94V-O specification. This compound is 100% reactive and does not contain any solvents or other volatiles. It contains a special air release agent. Master Bond Polymer System EP30M3FR is particularly recommended where a low viscosity is required and cured castings must withstand severe environmental conditions such as UL94V-O specifica-tion, and also exposure to various chemicals and temperature cycling up to 275°F. Adhesion to both similar and dissimilar substrates is excellent. The hardened material is an electrical insulator. Color of part A is black; part B is dark brown. Master Bond Polymer System EP30M3FR is widely used in the electronic, electrical, computer. construction, appliance, metalworking, automotive and chemical industries.
