High temperature resistant epoxy offers optical clarity
Master Bond EP30HT is designed for high performance general purpose bonding, sealing, coating and casting. This optically clear, two component epoxy features high temperature resistance and a room temperature cure. It conforms to Title 21, U.S. Code of Federal Regulations, FDA Chapter 1, Section 175.105 for Food Applications.
Featuring a superior combination of performance properties, Master Bond Polymer Adhesive EP30HT is widely used in the electronic, electrical, computer, optical, fiber-optic, medical, automotive and chemical industries. This medium viscosity, two component epoxy adhesive is ideal for general purpose bonding, sealing, coating and encapsulation applications. It is especially recommended where good flow properties are required and where bonded assemblies must exhibit superior dimensional stability.
EP30HT conforms to Title 21, U.S. Code of Federal Regulations, FDA Chapter 1, Section 175.105 for Food Applications. This system adheres well to both similar and dissimilar materials including metals, glass, ceramics, wood, vulcanized rubbers and many plastics. EP30HT produces high strength, rigid bonds which are remarkably resistant to chemicals including water, oil and most organic solvents. It is serviceable over the exceptionally wide temperature range of -60°F to more than 400°F.
In addition, EP30HT offers exceptional optical clarity with excellent light transmission properties. It has even been laboratory tested for 1,000 hrs at 85°C/85% humidity. The hardened adhesive is an outstanding electrical insulator, with a volume resistivity greater than 10-15 ohm-cm and a dielectric strength of 440 volts/mil.
Formulated to cure at room temperature or more rapidly at elevated temperatures, EP30HT has a four to one mix ratio by weight. It is 100% reactive and does not contain any solvents or other volatiles, making shrinkage after cure exceptionally low—0.0003 inches/in. EP30HT combines high temperature resistance with superb optical clarity.
