Zinc chromate Moomprimer

Description

Indy zinc chromate alkyd stainless is a type of primer based on alkyd resin containing yellow and green zinc chromate anti-corrosion pigment that is used on metal surfaces, especially metal niches. This coating acts as a stainless primer on the surface and requires a single-layer coating or alkyd coating to fully protect under different weather conditions. It is also widely used, especially in environments where gasulfur is available. Zinc chromate prevents corrosion by forming chromate hydroxide deposition between the paint and metal layer through the method of passivation or deactivation. Chromate Zinc or Zinc Chromium Oxide with formula ZnCrO 4 in yellow and green crystals، A type of anti-corrosion pigment or oxide pigment containing zinc anti-corrosion element with abbreviations Zn. The metal element zinc or zinc is sacrificed as metal and prevents corrosion or progression by creating a protective layer due to oxidation on iron and steel.

Implementation Method

Surface preparation:
1. The work should be free from rust and corrosion.
2. The minimum degree of cleanliness of the surface is Sa2½.
3. The substrate should be free of moisture, dirt, grease and oil.

The implementation is done in two stages:
First layer: A layer of zinc chromate alkyd rust protection should be diluted with oil thinner according to the application conditions and then applied with a brush, roller, airless or pistol with a minimum thickness and to make sure that the surface is fully coated.
Second layer: After 24 hours, apply the second layer of alkyd zinc chromate with a thickness that is appropriate based on the application and weather conditions.
At the time of execution, the ambient temperature should be between +10 and +40 degrees Celsius, the surface temperature should be 3 degrees higher than the dew point, and the relative humidity should be less than 85%.

Implementation Tools

✔ Paint Brush, Roller, Airless and Pistol spray.
