HACKENSACK, N.J., 19 Feb. 2015. Master Bond Inc. in Hackensack, N.J., is introducing the EP62-1LPSP optically clear epoxy for strength, electrical, and handling properties in bonding, sealing, coating, and encapsulation applications.

EP62-1LPSP adhesive is a reliable electrical insulator and has a volume resistivity over 1014 ohm-cm. This blend of high performance properties allows this product to be used in aerospace, electronic, fiber-optic, electro-optical, and specialty OEM applications.

With a tensile lap shear strength exceeding 2,000 psi, it bonds well to a variety of substrates including metals, composites, glass, and many plastics.

This optically clear adhesive has a non-critical four to one mix ratio by weight and features an open time of 12 to 24 hours at ambient temperatures. EP62-1LPSP has a thin mixed viscosity of 150 to 300 cps, which can be further lowered by adding heat.

Its low exotherm while curing allows it to be used for large encapsulations. It offers a variety of cure schedules and can be cured at temperatures as low as 60 to 70 degrees Celsius. Faster cures can be achieved at 125 C.

Featuring a glass transition temperature of greater than 125 C, EP62-1LPSP is a thermally stable system that is serviceable over the wide temperature range of -60 to 400 degrees Fahrenheit. It withstands exposure to chemicals such as water, fuels, oils, solvents, acids and bases.

EP62-1LPSP is available for use in standard half-pint, pint, quart, gallon, and 5 gallon kit containers. It can be applied by brush, paint roller, syringe or gun dispenser.
