Master Bond Polymer Adhesive EP30HT is a medium viscosity, two component epoxy adhesive for general purpose bonding 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 low viscosity is required for ease of application and bonded assemblies must exhibit superior dimensional stability. Shrinkage after cure is exceptionally low-0.0003 inches/in. EP30HT combines high temperature resistance with superb optical clarity. EP30HT-LO version fully meets NASA outgassing test. The EP30HT Conforms Title 21, U.S. Code of Federal Regulations, FDA Chapter 1, Section 175.105 & 175.300 for Food Applications. Master Bond Polymer Adhesive EP30HT produces high strength, rigid bonds which are remarkably resistant to chemicals including water, oil and most organic solvents, over the exceptionally wide temperature range of -60°F to more than 400°F. 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. Color of part A is clear, part B clear. Master Bond Polymer Adhesive EP30HT is widely used in the electronic, electrical, computer, optical, fiber optic, medical, automotive and chemical industries.
