The ability to withstand broad temperature swings can be the undoing of many adhesive systems. There may be sacrifices in chemical resistance, ease of use, or bond strength. Master Bond of Hackensack, NJ, says it has developed a one-component epoxy that offers best-of-class bond strength and chemical resistance over a service temperature range from 4K (-452F) to 350F.
When bonding aluminum, for example, Master Bond says its Supreme 10HTFL offers tensile lap shear strengths exceeding 2,000 psi. Master Bond also says it performs well in ASTM D1876, the standard test method for peel resistance of adhesives (T-Peel Test).
“Its performance properties are at their most impressive when bonding substrates with wide differences in their thermal expansion coefficients,” says Robert Michaels, Master Bond’s vice president of technical sales. Target bonding applications include a variety substrates, including aluminum, steel, engineering thermoplastics, fiber reinforced composites, ceramics, glass, and wood.
