Introduction of Surface Treatment Coating for Electric Heating Tube vacuum deposition Machine

Coating is a solid continuous film obtained from a single application of paint, which is a thin plastic layer applied to metal, fabric, plastic, and other substrates for protection, insulation, decoration, and other purposes. Coatings can be gaseous, liquid, or solid, and the type and state of the coating are usually determined by the substrate to be sprayed.

Benefits of coating layer:

Introduction of Surface Treatment Coating for vacuum deposition Machine

1. Penetrating Surface Treatment Coatings

The basic principle of permeable surface treatment coatings is to use a resin with strong permeability as the base, combined with polar solvents and penetrating agents to ensure good performance and enhance the adhesion of the coating.

2. Stable surface treatment coating

The basic principle of stable surface treatment coatings mainly relies on the reaction between active raw materials in the coating and active components in the rust layer. The commonly used active raw materials include zinc oxide

Zinc phosphate, zinc chromate, barium chromate, organic nitrogen base chromate, calcium chromate, aluminum tripolyphosphate, sodium nitrite is added to some formulas, and strontium chromate is considered necessary.

3. Conversion type surface treatment coating

Transforming surface treatment coatings, also known as reactive rust resistant coatings, do not contain film-forming substances and therefore require additional primer coordination. If they contain film-forming substances, they are called rust resistant conversion primers.
