9. Precautions

1. Coatings and thinners should be sealed and stored in a cool place, protected from fire, leakage, sun protection, high temperature, and away from fire sources.

2. The storage period of the paint is one year, please be sure to use it up within one year, so as not to affect the quality.

3. The paint should be fully stirred after opening the can, and the residue at the bottom of the can is mixed into the color mixing tank, so that the paint sinks to the bottom and causes a color difference.

4. After the paint is thinned, filter it with a 200-mesh mesh cloth. After spraying, the workpiece should be placed in a dust-free environment for 5-10 minutes, and then put into the oven.

The mechanism of anti-corrosion coatings

Anti-corrosion coatings can be divided into corrosion-resistant coatings, which require acid or alkali resistance, and acid and alkali resistance can be alternated or performed simultaneously. The pH value of the corrosion medium can be corroded from 1 to 12. The coating has low alkali resistance, acid aging resistance and good adhesion of the anti-corrosion layer. The anti-corrosion principle of anti-corrosion coating mainly includes three aspects: electrochemical action, chemical principle and physical principle.
