Prevention of common defects in water-based anticorrosive coatings!

Anti-corrosion coating is an indispensable coating in paint coatings, which has an anti-corrosion effect on objects and protects the service life of objects

Common defects of water-based anticorrosive coatings

The advantages or defects of a batch of newly prepared and packaged anticorrosive coatings are unclear.

Prevention of common problems of water-based anticorrosive coatings

According to the experience of research and development practice, we have taken the following measures to prevent and solve the above-mentioned defects: prevent them from the source of the formula, that is, try to reduce the surface tension of the anticorrosive coating

Choose matching additives

1.

Reasonably take the above measures, those self-drying primer or baking paint peeling, blistering, poor adhesion and other defects, the outer paint surface is not smooth, not smooth, not full and other defects, the paint layer is not long service life, etc.
Defects can be effectively prevented and resolved
.
For the softness, sagging, and uneven surface of the water-based baking paint of the packaging barrel, we screened the appropriate resin and adjusted the ratio, and replaced it with additives that reduce surface tension, prevent sagging and increase leveling
.
For general-purpose water-based paints such as roughness, foaming, shrinkage, poor appearance, post-thickening or post-thinning, we use the "four two" additives to overcome the defects
.
"Four two", that is, two or more wetting and dispersing agents, two or more anti-foaming and defoaming agents, two or more film-forming cosolvents, and two or more rheology additives
