Master Bond EP30FLAO Flexibilized, Thermally Conductive Epoxy Adhesive
Categories: Polymer; Thermoset; Epoxy; Epoxy, Thermally Conductive

Material Notes: Master Bond Polymer System EP30FLAO is a two component epoxy resin system for high performance potting, bonding, sealing and coating. It is formulated to cure at room temperature or more rapidly at elevated temperatures, with a ten to one mix ratio by weight. It has an attractive balance of performance properties including high thermal conductivity, superior dimensional stability, mechanical properties, toughness and electrical insulation. EP30FLAO is a low viscosity epoxy with excellent flow characteristics making it ideal as a thermally conductive potting compound. It also has a desirably low coefficient of thermal expansion which makes it an excellent choice for many potting applications.

Vendors: Master Bond is a leading manufacturer of adhesives, sealants, coatings and potting compounds. Master Bond’s vast product line consists of over 3,000 epoxy, polyurethane, silicone, cyanoacrylate and latex adhesives that vary in viscosity, cure speed, strength, chemical resistance, electrical properties, etc. Our custom adhesives offer design flexibility and provide excellent bonding performance.
