T/DLSHXH 002-2017 "Waterborne polyurethane coatings" stipulates the technical requirements, performance indicators, test methods and application specifications of waterborne polyurethane coatings. Waterborne polyurethane coatings use water as a solvent, have the characteristics of low vocs (VOC) emissions and strong environmental friendliness, and are widely used in surface painting in construction, furniture, automotive and other industries. The standard details the composition of coatings, abrasion resistance, adhesion, weathering resistance and environmental performance requirements, and puts forward specific guidance on coating process, construction environment and quality control. Through unified technical specifications, the standard provides a scientific basis for the production, selection and application of waterborne polyurethane coatings, aiming to improve the environmental friendliness and durability of coatings and promote the green development of the coatings industry.
