Application of waterborne coatings

Waterborne building paint

According to different coating parts, it can be divided into exterior wall coating, interior wall coating, floor coating and roof coating.In addition to high adhesion, exterior wall coatings also require excellent weather resistance, acid and alkali resistance, freeze and thaw resistance stability and ultraviolet radiation resistance.In addition to decorative effect, interior wall coatings should also have excellent water resistance, scratch resistance and high air permeability.The floor coating is similar to the cement base coating, which requires wear resistance, anti-slip and stain resistance.

Waterborne automotive paint

The automobile industry is a large user of paint, the amount of paint is second only to the construction.Automobile coating is also the performance and coating technology requirements are relatively high varieties.In China, cathodic electrophoretic paint is used for car body priming, which is completely water-based.Because the metal parts of the car are not exposed, electrophoresis coating is basically used, and the bottom layer is integrated.And some trucks, buses coating quality requirements are relatively low, only a small amount of body primer using electrophoresis paint, a considerable part of the body, chassis, frame and parts using water-based epoxy ester or water-based acrylic amino impregnation paint, and even a large part of the still use solvent antirust primer.At present, in Europe and the United States, all the car primers, more than 80% of the car paint, more than 50% of the metal flash primer paint has achieved water-based, and water-based cover finish industrialized application is less.In China, in addition to the body primer, the middle coat and top coat are basically solvent-based coatings.

Waterborne plastic coating

With the development of science and technology, plastic products have been widely used in household appliances, automobiles, building materials, office equipment, electronic communication and medical equipment and other industries, is the national economy and national defense construction indispensable important materials.But in addition to the performance of the plastic itself, such as ultraviolet light resistance is not ideal, after processing and molding, it often produces various surface defects.Therefore, the plastic surface coating, to achieve decorative effect, improve corrosion resistance, weather resistance and service life.Current, on the market can be used at the water-based coating variety of plastic surface and water-based woodware coating similar, mainly water-soluble coating and latex coating.According to the classification of film forming materials, waterborne plastic coatings mainly include waterborne acrylic acid, one-component waterborne polyurethane, two-component waterborne polyurethane coatings and so on.Compared with other waterborne coatings, the two-component waterborne polyurethane coating has excellent performance and good adhesion, which can meet the requirements of most plastic varieties for coating performance. In the future, it will be one of the main varieties of waterborne plastic coatings.
