Flexibilized Epoxy-Urethane Blend Adhesive, Sealant and Potting Compound

Two component, room temperature curing elastomeric Master Bond EP30DP has exceptional toughness, abrasion resistance and is cryogenically serviceable. EP30DP has a low viscosity and can be cast in thick cross sections (e.g. several inches) without the development of excess exotherm during cure. It has high strength properties and outstanding impact and fatigue resistance.EP30DP also has low water absorption, low moisture permeability and high hydrolytic stability.

Flexibilized, Epoxy-Urethane, Adhesive, Sealant, Potting Compound

Master Bond EP30DP has a 100 to 10 mix ratio by weight. It has a working life of 2 ½ to 3 hours for a 100 gram mass at 75°F. Cures can be accelerated by use of heat. Elongation at break is 80%. EP30DP is 100% reactive and does not contain any solvents or volatiles. It is readily repairable and can be easily removed with a razor blade or similar tool. Formulations do not contain any free isocyanate and EP30DP is quite safe to us when proper industrial hygiene practices are observed.

This compound has excellent electrical insulation properties and will withstand exposure to thermal cycling. Shore D hardness is 85. It has a tensile strength of 1,450 psi and a dielectric strength of > 420 volts/mil. This unique polymer system has a shelf life of 6 months in original unopened containers stored at 75°F. It is available for use in ½ pint, pint, quart, gallon, and 5 gallon kits.
