CoolTherm® EP-343 coating is a two-component, dielectric epoxy coating recommended for coating

printed circuit boards, semiconductors and heat sink assemblies. CoolTherm EP-343 coating efficiently

distributes heat from the circuits throughout the coated surface of the board.

Features and Benefits:

• High Thermal Conductivity – provides high electrical insulation with exceptionally good heat transfer.

• Environmentally Resistant – provides good resistance to water and a wide variety of chemicals.

• Broad Temperature Range – can be used on parts and devices that experience operating temperatures from -65°C to +130°C.

• Low Viscosity – maintains low viscosity, allowing easy application with conventional spray equipment.

• MIL-E-5272 Compliant – meets requirements of Military Specification MIL-E-5272.

• Lasting Appearance – cured system is free of dimpling; provides good edge coverage and excellent hiding power, even in thin applications.

Shelf Life/Storage:

Shelf life is one year for CoolTherm EP-343 resin and two years for CoolTherm EP-343 hardener when stored at 25°C in original, unopened container.
