Press Release Summary:
Suited for bonding, encapsulation, and coating, 2-component EP21LM-3 develops tensile modulus greater than 100,000 psi and tensile shear strength greater than 2,300 psi. Viscosity of 37,000 cps enables product to flow evenly and smoothly without application of pressure. When cured, polymer has Shore D hardness of 64 and resists thermal cycling as well as water, oil, fuels, and most organic solvents over temperature range of -65 to +250Â°F.
Original Press Release:
Epoxy Has Outstanding Dimensional Stability
Master Bond Inc., Hackensack, N.J. has developed EP21LM-3, a two component, medium viscosity epoxy resin system for high performance bonding, encapsulation and coating. EP21LM-3 readily develops high physical strength properties including a tensile modulus greater than 100,000 psi (690 MPa) and a tensile shear strength greater than 2300 psi (16 MPa). It is easy to apply. Having a viscosity of 37,000 cps the product flows evenly and smoothly without application of pressure, wets surfaces and fills volumes quickly and completely.
The cured polymer has a Shore D hardness of 64. It features remarkable resistance to thermal cycling and many chemicals including water, oil, fuels and most organic solvents over the temperature range of -65°F to +250°F. Adhesion to metals, glass ceramics, wood, vulcanized rubbers and many plastics is excellent. The EP21LM-3 system is a superior electrical insulator with a dielectric strength over 350 V/mil and a volume resistivity of 1014 ohm-cm. Master Bond EP21LM-3 system is widely used in the electronic, electrical, computer, construction, metalworking, appliance, automotive and chemical industries. It is available pint, quart, gallon and 5 gallon containers.
