Environmental Friendliness: Water-based acrylic resins use water as a solvent and do not produce harmful gases or pollutants during use, meeting environmental protection requirements. Weather Resistance: They have good weather resistance and can be used under various climatic conditions, being less susceptible to the effects of ultraviolet light, oxygen, and humidity. Good Adhesion:...

Polyurethane materials are a general term for a class of macromolecular compounds that have urethane structures in their molecular structure. They are usually prepared by the polyaddition reaction of diisocyanates and polyols. Polyurethane polymers possess both polar functional groups that allow for physical cross-linking and non-polar and flexible chain segments. When used properly, these po...

- admin
Sometimes, a slight ammonia smell is detected in water-based acrylic emulsions, which confuses many people: is this normal or is there a problem? First, we need to clarify that acrylic emulsions themselves do not produce an ammonia smell. However, during their production, ammonia-containing additives may be added to adjust their performance or improve their stability. These additives gra...

Acrylic resins are an indispensable and commonly used resin in water-based coatings. They are widely used in metal coatings, ABS and PC coatings, and glass coatings requiring hardness, especially solid acrylic resins. There are many types of solid acrylic resins. Some solid acrylic resins can be used to produce water-based paints, including the currently popular UV-cured coatings and high-sol...

01 Polyurethane The structure of polyurethane is formed by the reaction of polyisocyanates (e.g., diisocyanate OCN-R-NCO) and polyols (e.g., diol HO-R-OH), where urethane segments are repeating structural units. Polyurethane structures have structures similar to amide and ester groups; therefore, the chemical and physical properties of polyurethane are between those of polyamides and polyesters. S...
