Problems solved by technology

[0002] Currently used in home decoration, wood coatings in furniture production are basically solvent-based coatings, which contain a large amount of volatile organic compounds VOC, pollute the environment, damage the health of painters and consumers, and are flammable and explosive, and waste Petroleum resources, water-based wood coatings use water as the dispersion medium, low VOC content, low odor, no triphenyl, free TDI, no harm to the human body, no pollution to the environment, etc. The water-based wood coatings on the market now have the advantages of clear surface The paint has shortcomings such as water resistance, poor chemical resistance, low hardness, fullness, hand feeling, and poor adhesion resistance.
