A81 aldehyde resin (also known as poly formaldehyde resin) product is colorless and transparent to the micro - yellow - resistant yellow - formaldehyde resin, also known as universal resin. The appearance is divided into fine granulation after regular semi-circular irregular small particles and without granulation process, as a special hard resin for solvent based coatings and inks, solvent-free coatings, waterborne coatings, powder coatings, resin modification and other system. A81 can obviously improve the resistance to yellowing, shorten drying time, increase the hardness, fullness and luster of the film, increase the solid content. Because of the low viscosity of A81, and reduce the use of organic solvents in the paint industry, reduce the environmental pollution caused by VOC emissions. Sengm formaldehyde resin A81 has good wettability of metal pigment and other pigment dispersion, while soluble in most organic solvents, so it is very suitable for oil soluble ingredients. In particular, the cost of general color can be reduced by more than 40%, which is far superior to the adaptation of low solvent similar products. A81 can also be used for powder coatings and chlorinated rubber paint, etc.. In short, the product performance has reached even more than similar foreign products, is a paint, ink and other industries use a very wide range of special resins.
