Environmentally friendly coating

Product Details

Chongqing environmental protection coatings are generally divided into paints and watercolors. The paint mainly uses thinner as a diluent, and contains a large amount of harmful substances, such as benzene, toluene, formaldehyde, etc., and volatilizes for 15 years, which is extremely harmful to the human body. The paint uses water as a diluent, and does not contain toxic and harmful substances that are harmless to the human body, such as benzene, toluene, xylene, and formaldehyde. That is, the brush. There are usually two types of water-based paint emulsions: acrylic emulsions and polyurethane emulsions. Among them, polyurethane has better physical properties, and the coating is relatively stable, but the cost is high. In current domestic coatings, polyurethane is rarely used as an emulsion. Acrylic acid is currently the main emulsion for home interior wall waterborne coatings. Acrylic type has low cost and poor performance. After the film formation, "hot sticky and brittle" phenomenon is likely to occur. That is to say, when the temperature is too high, dust tends to stick to the wall, and when the temperature is too low, the dust is relatively easily broken.

With the continuous improvement of people's environmental awareness, environmentally friendly coating products have replaced the traditional solvent-based coatings with their pollution-free and safe features, which has become the consensus of the whole society. in. Water-based paints are water-based solvents that uniformly disperse film-forming substances in water, also known as water-based paints or latex paints. Due to its wide source, easy purification, low cost, low viscosity, good coating and non-toxic, non-irritating and non-flammable, it has become the main development direction of “environmental coating”. Waterborne coatings mainly include waterborne epoxy resin coatings, waterborne polyurethane coatings, waterborne light curing coatings, etc., and are widely used in automobiles, construction, electrical appliances, instrumentation and other industries for their excellent performance.
