Encapsulation of air-conditioning electromagnetic clutches

The automotive air-conditioning electromagnetic clutch is a power transmission device between the vehicle’s engine and the air-conditioning compressor; the air-conditioning compressor is driven by the vehicle’s engine via the electromagnetic clutch.

Product Requirements and Features:

(1) It has low viscosity and high penetrating power, enabling it to fill the space between components and coils;

(2) The curing exothermic peak is low, and curing shrinkage is minimal;

(3) The cured material exhibits excellent electrical and mechanical properties, has good adhesion to a wide range of materials, and has a low coefficient of linear expansion;

(4) Properties such as heat resistance, weather resistance, thermal conductivity and resistance to alternating high and low temperatures;
