Coatings for iCARe®
Description
Electrical steel varnishes for non-oriented grades are designed to enhance the behaviour of fully processed electrical steels. Their main purpose is to provide inter-laminar insulation and to improve the punchability of these steels. Each type has its own specific properties, such as insulation level, punchability effect, corrosion protection, temperature resistance, weldability and compatibility with dot gluing; hence it is material use that determines the optimum choice of varnish. All varnishes have been selected and developed to be environmentally friendly: they are hydro-soluble and chromium-free.
The C5-type varnish is is the preferred varnish for automotive applications: it is a pigmented varnish, made with thermo-stable resins, mineral products and pigments.
Applications
These coatings are used for fully processed grades for hybrid and electric traction machines and compressors. For alternators, uncoated solutions can be used.

Recommendations
The raw materials used in these coatings have a chemical composition – both in the liquid and cured varnish state – which does not require specific protective measures during the processing of the coated steels or during use in a given application.
