Coating Chemicals

We provide wide range of coating chemicals from C-3, C-5 and C-6 classes which are suitable for various coating systems with varying line speeds.

Classification of Coating Types:

C-3 Coatings Chromium Free

The C-3 coating will enhance punchability and exceptional insulation property of electrical steel. It has high level of adhesive properties. Does not withstand stress relieving annealing (SRA).

Applications -

For high level of inter laminar resistance as required.
For small and medium sized motors & transformers

C-5 Coatings

Used for excellent surface resistivity both before and after stress relief annealing (SRA). Improved punch and die life during stamping operations. Better adherent film with improved surface resistivity. Avoids yield losses and gives better performance. Withstands stress relief annealing and other high temperature treatment.

Applications –

Used for refrigerator motors
Small to large sized motors and transformers
Large turbo generators.
For high temperature resistance and weldability requirements.

C-6 Class Coatings Waterborne & Chromium Free

Special Coating suitable for high frequency applications and other power house equipment’s. Provides thick coatings and therefore increases surface resistivity. Has increased insulating ability of the coating. Offers excellent punchability & withstand high temperature “burn off” treatments used during rebuilding of motors. It provides ridge free coatings. Lower shrinkage. Has excellent match of thermal coefficient of expansion with steel due to high pigment concentration.

Applications –

Suitable for large and medium sized motors.
H2 cooled generators.
C-6 coatings are ideal for magnetic cores of contractors.
high frequency application because of its ability to withstand vibrations.
