Values shown are based on testing of laboratory test specimens, conditioned at 70°C for 14 hours, and represent data that fall within the standard range of properties for the natural material. They are not intended for use in establishing maxiumum, minimum or range of values for specification purpose.

Material preparation

EPALINE 770 A 15 15 is hygroscopic and therefore has to be dried before use. The recommended drying conditions are 2-3 hours at 160 - 180°F in a desiccant dryer.
