Key Features
- Good flow properties
- High-temperature resistance
- Withstands aggressive chemicals
- High compressive strength
Master Bond EP35AOLV is a two-component thermally conductive, electrically isolating epoxy for bonding, sealing, and potting. The mix ratio is a forgiving 100 to 50 by weight with both Parts A and B being highly flowable. The working time is exceptionally long, 12-24 hours at room temperature. EP35AOLV requires an elevated temperature cure with the optimum being 2-3 hours at 300°F followed by a post-cure of 3-4 hours at 300-350°F. This filled system is highly dimensionally stable and has low shrinkage upon curing.
The epoxy bonds well to a wide variety of substrates, such as metals, glass, ceramics, composites, and many plastics. Its forte is its ability to withstand high temperature and pressure in an aggressive chemical environment, including those found in down hole. The filler imparts high compressive strength to the system. The service temperature range extends from -60°F to +500°F. The color of Part A is gray and Part B is off-white. EP35AOLV can be used in aerospace, electronic, specialty OEM, oil and gas processing, and other industries where high temperature and chemical resistance along with thermal conductivity are required.
