Waterborne acrylic anti-corrosion coatings are usually used in medium and light anti-corrosion fields, usually consisting of a combination of three coats of primer, middle coat and top coat to form a coating system and play a role. Primer is the basis of the entire coating to prevent the penetration of water, ions and oxygen. It has good adhesion and corrosion resistance. It can be used with water-based epoxy and acrylic primers, and it can also be used with solvent-based coatings. Form a composite system; the intermediate coating is mainly used to improve the adhesion with the topcoat and primer, make the adhesion between the two coating films closer, increase the coating thickness, and improve the shielding ability of the entire coating system; topcoat It has beautiful decoration and anti-permeation effect. It is usually a pigment-free varnish to improve the weather resistance of the entire coating.

Water-based acrylic paint uses water as the dispersion medium, is non-toxic, environmentally friendly, easy to clean and non-flammable, and can be used even below 5°C. It is a green, pollution-free and environmentally friendly paint. However, the coating film has problems such as easy "flash rust" and poor solvent resistance, which has also become a major obstacle to its application and promotion.
