Dolph’s® offers a wide range of coatings for the protection of electrical and electronic applications. These products are specially designed to meet the most demanding conditions of the electrical insulation and electronic protection markets.

Pigmented coatings are used on motors, generators and transformers to improve protection against humidity and chemicals. Coating also improves the anti-tracking properties of electrical parts. Coatings are available in a variety of different spray cans.

In the electronics market segment, transparent coatings are used mainly to protect fragile or exposed components against humidity and to improve thermal resistance. A large choice of highly versatile, easy-to-use products are available in Dolph’s® new, comprehensive portfolio.

Dolph’s® varnishes and resins are integral components of insulating systems for all classes of rotating equipment, motors and generators. These materials provide environmental protection, vibration reduction and, in some cases, additional dielectric strength. The choice of the right material depends on the end-use application.
