LKM has the characteristics of high elasticity, strength, electrical stress resistance, good anti-friction performance, easy to use, small thickness and shrinkage.
The nominal thickness of the paint is 0.08 to 0.2 mm. When used at temperatures up to 105 °C, the shrinkage is less than 1%.
The average breakdown voltage on the 6 mm electrode before kinking was 6–9.5 kV, and after kinking it was 3.6–5.5 kV. LKM retains its characteristics when heated to 105 °C.
