Master Bond Polymer System EP30QF is a quartz filled, two component epoxy for high performance bonding, sealing, coating and casting formulated to cure at room temperature or more rapidly at elevated temperatures with a four (4) to one (1) mix ratio by weight. This adhesive is 100% reactive and does not contain any solvents or other volatiles. It is especially recommended where high tensile modulus, outstanding compressive strength and superior dimensional stability are important requirements. Linear shrinkage after cure is an exceptionally low < 0.0002 inches/in. A lower viscosity version called EP30QFLV is also available. Master Bond Polymer System EP30QF produces high strength, rigid bonds which are remarkably resistant chemicals including water, oil and most organic solvents, as well as cold sterilants, ETO and gamma radiation. Adhesion to both similar and dissimilar materials including metals, glass, ceramics, wood, vulcanized rubbers and many plastics is excellent. The hardened adhesive is an electrical insulator. The color of part A is tan and part B is tan. Master Bond Polymer System EP30QF is widely used in electronic, electrical, computer, optical, metalworking, appliance, automotive and chemical industries.
