Description

Technical Field

[0002] Primer is the first layer of the paint system, which is used to improve the adhesion of the topcoat, increase the fullness of the topcoat, provide alkali resistance, provide anti-corrosion functions, etc. At the same time, it can ensure the uniform absorption of the topcoat so that the paint system can play the best effect. It is wrong to say that primer is not needed if the topcoat is of good quality, because the functions of topcoat and primer are different. Topcoat focuses more on the final decoration and appearance, while primer focuses on improving adhesion, anti-corrosion function, alkali resistance, etc.; primer needs to be produced by a corrosion-resistant primer mixing line and is equipped with a special mixing process.
