Surface Insulation Coating
We provide Type A, H and D of Coatings. Users may select a qualified coating type from them in accordance with
interlamination resistance, sheet punching ability, from resistance, heat resistance and other characteristics.
Coating A: Coating A is a semi-organic thin coating with excellent sheet-punching ability, corrosion resistance, from
Resistance and high lamination resistance. It has extraordinarily excellent weld ability and is suitable for medium and
Small size electric motors and motors for household appliances. It is equivalent to the coat A1of KSC and coating T4
of Wuhan Steel
Coating H: Coating H is a semi-organic thick coating with excellent sheet-punching ability, corrosion resistance, freon
resistance and high lamination resistance. It has extraordinarily excellent weldability and is suitable for medium and
small size electric motors and motors for household appliances which requires higher sheet punching ability It is
equivalent to A1 of KSC and T4 of Wuhan Steel
Coating D: Coating D is an inorganic coating with excellent weldability and heat resistance. It is suitable for medium
and small size electrical motors and especially fit in the application of stress-relief annealing at a high temperature.
It is equivalent to coating C4 of AISI and the coating of T3 of Wuhan Steel

Unless there are specific descriptions, the surface insulation coatings designed for steel grade are all coating A
