Master Bond Polymer System EP120SP is a two-component epoxy/anhydride system for high performance resistant gel coats ancl protective coatings for filament wound structures. It is, 100% reactive and does not contain any solvents or diluents. Master Bond Polymer System EP120SP can be readily gelled at temperatures as low as 100-120°C. Full cure is obtained at temperatures in the 125°C to 150°C range. The cured polymer features superior physical strength properties and has a heat distortlon temperature of around 137°C. Master Bond EP120SP is supplied in the form of two liquid components each having a minimum stability of six (6) months when stored at temperatures of around 25±5°C.
