Master Bond EP30HV, a two component epoxy, features wide applicability in the electronic, electrical, computer, aerospace, automotive, optical, fiber optic, medical and chemical industries. Formulated for bonding, sealing, coating and casting applications where high strength and optical clarity are needed, it complies with FDA Chapter 1, Sections 175.105 for food applications.

EP30HV offers high light transmittance from 350-2,400 nm and has a refractive index of 1.55 at room temperature. Its enhanced electrical and thermal insulation properties include a volume resistivity over 10¹⁵ ohm-cm, a dielectric strength of 440 volts/mil and a low coefficient of thermal expansion. With a low mixed viscosity of 4,000 cps, this system is often used in small potting and encapsulation applications, especially for electronic or optical assemblies.

Featuring a forgiving four to one mix ratio by weight, EP30HV is easy to handle and cures at room temperature in 24 hours or faster at elevated temperatures. This epoxy produces high strength bonds that have a tensile strength exceeding 9,000 psi and a compressive strength greater than 14,000 psi at ambient temperatures. Linear shrinkage is low at 0.0003 inches/inch. It also resists a wide variety of chemicals including water, oils, acids, bases and many solvents.

Serviceable over the wide temperature range of -60°F to +300°F, EP30HV bonds well to metals, glass, ceramics, wood, rubbers, and many plastics. It is available for use in pint, quart, gallon and five gallon container kits. This two part system has a shelf life of up to one year if stored in its original, unopened containers.
