covering varnish 188

covering varnish 188. It has good electrochemical, thermal, mechanical and chemical properties, mostly varnish and coloured paint. Insulating paint is a special kind of lacquer in lacquer. Insulating varnish is an important insulating material that can be solidified into insulating film or insulation under certain conditions based on polymer. Insulating varnish is composed of base material, flame retardant, curing agent, pigments and fillers, and solvents.

Requirement

1. excellent insulation performance

2. good adhesion and high mechanical strength;

3. the contractile stress is small;

4. the heat resistance should meet the different requirements of the transformer.

5., outdoor or special environment should meet its special requirements, such as radiation protection, corrosion protection, UV protection and so on.

6. the process is good, such as good operation, non-toxic or low toxicity, short drying time and so on.
