LORD JMC-700K
PRODUCT DESCRIPTION:
LORD® JMC-700K coating is a thermal-cure epoxy resin specially designed for thin film coating of heat sinks and magnets. LORD JMC-700K coating provides electrical insulation, heat resistance, and oil resistance with a single coat application. This coating can be used in a variety of automotive applications including cooling plates, heat sinks and motor magnets used in electric vehicles, as well as automotive parts and industrial machine applications.
Features and benefits:
Good adhesion – provides strong adhesion to substrate.
Broad temperature range – can be used on parts and devices that experience operating temperatures from -40°C to +180°C.
Environmentally resistant – provides excellent resistance to heat, oil and moisture.
| Heat resistance test 180˚C x 1500 hrs | Pass |
| Cycle test -40˚C to +170˚C, 1500 cycles | Pass |
| Oil resistance test 150˚C x 2000 hrs | Pass |
| Humidity resistance test 85˚C, 85% RH x 2000 hrs | Pass |
Application:
Surface preparation – thoroughly clean surfaces prior to coating application to remove all dirt, oil, grease and oxides.
Mixing – thoroughly stir the coating before use. If dilution is needed, use LORD JMC-700ST thinner or methyl ethyl ketone (MEK) as a dilatant.
Applying – apply coating using dip or spray methods. Regardless of the application method, the recommended dry film thickness of LORD JMC-700K coating is 10-100 micron.
Curing – allow coating to cure for 30 minutes at 180°C. This time-at-temperature profile refers to the time the material should be allowed to cure once it reaches the target temperature. Allowance should be made for oven ramp rates, parts with large thermal mass and other circumstances that may delay the material actually reaching the target temperature.
