Green additive solutions for Eco-friendly water-based coating

With the improvement of people's awareness of environmental protection, green coatings have gradually become the mainstream of consumption and market. “Green coating” mainly refer to energy-saving, low-pollution, low-VOC water-based coatings, powder coatings, solvent-free coatings, radiation-curing coatings...

Among them, water-based coating not only reduces the cost of coatings and fire risks caused by the presence of organic solvents in the construction, but also greatly reduces the VOC, and thus water-based coatings are the popular trend in the development of green coatings!

Ø Main types of water-based coatings:

u Water-based polyurethane coating

The hydroxyl group and isocyanate react to form the ammonia ester bond to form the film of polyurethane coatings.

Polyurethane coatings are characterized by their bright color and luster and can be applied to the surfaces of high-grade wood, pianos and large passenger aircraft. At the same time, it has excellent chemical corrosion resistance, so it is widely used in the anti-corrosion coating of chemical equipment and solvent storage tank industry.

u Water-based acrylic coating

Acrylic coating is a water-based coating made from pure acrylic polymer emulsions with other additives. Initially it was widely used for automotive refinishing, and nowadays it has been developed as a decorative paint and for painting metal surfaces.

u Water-based epoxy coating

Water-based epoxy coating has the advantages of excellent adhesion of paint film, good chemical resistance, small shrinkage force and good electrical insulation. Currently it is widely used in the coating of air conditioner outer machine and electronic industry.

Ø Do you know the main applications of water-based coatings?

Automotive industry

Waterborne paints have also been used in automotive refinishing for more than 20 years. Since the VOC emission of primer paints accounts for nearly 50% of the VOC emission of all automotive refinish paints, if measured in terms of VOC produced per unit area, the use of water-based primer paints together with high solids varnish reduces the VOC emission by up to 75.6%. Therefore, the global automotive refinish paint field mainly promotes and widely used water-based primer.

Wood coatings

Water-based coating is applied to the decorative protection of wooden doors, windows, furniture, flooring and bamboo appliances, which has become a new hot spot in the development of water-based coatings.

The main varieties of water-based wood coatings are as follows, in which acrylic is the main ingredient, and waterborne wood coatings in which a synthetic compound of acrylic and polyurethane is the main ingredient, as well as waterborne coatings in which polyurethane is the main ingredient.

Decorative coatings

In home decoration, water-based paint is mainly used for painting walls and ceilings. Its non-toxic, odorless, eco-friendly and healthy properties make it an ideal choice for interior decoration. Water-based paint is not only colorful and quick drying, but also can effectively enhance the beauty of home decoration. In addition, water-based paint has good scrub resistance and moisture resistance, making the wall more durable!‌

Ø How to obtain the high quality eco-friendly water-based coating?

By selecting the right UV absorbers, light stabilizers and antioxidants to be added to waterborne paints, the long-term weathering resistance of the paint can be significantly improved, and the gloss of the coating can be maintained, avoiding surface cracking and spotting.
