The composition reduces volatile organic compounds (VOC) and has the same performance as existing water-soluble soft-touch coatings. It can protect the health of operators and reduce odors in cars as much as possible. Productivity is also improved using this composition. The composition also improves scratch resistance thereby improving film quality. Problems with cracks and corrosion of plastic parts caused by the strong solvents used in oil-based paints can also be addressed. The adhesion between polypropylene parts and coatings is improved and no pretreatment is required, so processing time can be shortened and costs can be reduced. 200807094 Water-based automotive metal flash primer: CN101029197/China: Shanghai Jiebang Fine Chemical Co., Ltd. (Tang Jiahua, etc.).-2007.09.05.-200610024211.4(2006.02.28); IPCC09D133/00 The present invention relates to a water-based automotive metal flash primer Paint, consisting of 10% to 20% water-based polyurethane dispersion, 20% to 30% water-based acrylic resin, 5% to 10% water-based aluminum silver paste, 1% to 5% compound thickener, and 0.1% copolymer dispersant ~1%, defoaming agent 0.1% ~ 1%, wetting agent 0.1% ~ 1%, co-solvent 2% ~ 8%, water 30% ~ 50%. The effect of the invention is safety and environmental protection. It replaces organic solvents with water and greatly improves VOC emissions from the automobile painting assembly line. Fabric finishing agent 200807095 Water-based polyurethane, organic silicon and acrylic IPCC09D175/04 The invention relates to a method for preparing waterproof, breathable, moisture-permeable and antibacterial coating glue by copolymerizing water-based polyurethane, organic silicon and acrylic acid.
