Hard, rigid curing adhesives, sealants and coatings offer high physical strength properties. They are commonly employed in many structural bonding applications. These systems cure at room temperature, upon exposure to heat or exposure to UV light.
Key Benefits of Master Bond's Rigid Curing Compounds
Master Bond's rigid curing compounds are designed to offer outstanding performance in harsh environments. Advantages of this type of system include:
- High tensile and tensile shear strength
- Wear resistance
- Dimensional stability
- Exceptional compressive strength
- High glass transition temperature (Tg)
- Superior chemical resistant properties
Master Bond Adhesive System EP30HT
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.
