Varnish

        

Varnish

Varnish is the common name for insulating paint. It is an important insulating material based on high-molecular polymer that can be cured into an insulating film or insulation under certain conditions. Vanish is used for impregnation or coating of transformers, coils, and enameled wires. It is widely used in electrical products and electronic parts, various types of coils, transformers, PC circuit boards, resistors, generators, etc.

The main purposes of using Vanish are in the following:

  1. Insulation: The insulation protection of the winding can prevent insulation damage caused by high-speed winding.
  2. Fixation: It can strengthen and improve the adhesion during welding and reduce overall noise.
  3. Heat dissipation: with excellent heat dissipation, the thin film of Vanish can quickly promote heat dissipation.
  4. Moisture-proof and rust-proof: It can isolate the moisture around the product to prevent the  transformer from rusting.

Feature Comparison:

Our company acts as the agent of the world's leading brand: Showa Denko (Hitachi Chemical) Vanish.

(Showa Denko) Hitachi Chemical mainly produces non-solvent varnish water. Compared with the common commercially available solvent-based Vanish, the differences are as follows:


According to UL heat-resistant temperature, our current sales products can be divided into three categories:

1. 155°C (Class F): WP-2952F-2GY

Being mainly used in high-frequency transformers for low-temperature baking and fast hardening with excellent plasticity. It can be matched with more than 70 sets of mainstream insulation systems.

2. 180℃(Class H):WP-2854

Being mainly used in the stator and rotor of electric tools and home appliances. It has strong high temperature adhesion and rapid hardening.

3. 200℃(Class N):WP-2008

Being mainly used in products with low VOC requirements, such as automobile stators and rotors. Solvent-free epoxy resin varnish, with no added styrene.

4. 220℃(PAI resin):HCI-100

High heat-resistant polyamide-imide resin solution (Polyamide-imide, PAI). Being mainly used in non-stick pan coatings and metal processing parts, such as pistons, cams and other lubricating coatings
