GB 18581-2001 "Indoor decoration materials solvent wood coatings in the limit of harmful substances" standard stipulates the maximum allowable content of solvent wood coatings in harmful substances, designed to control the content of vocs (VOCs), heavy metals and other harmful substances in Coatings, in order to reduce the harm to human health and the environment. The standard specifies the limit requirements of formaldehyde, benzene, toluene, Xylene and other harmful substances in Coatings to ensure that the product will not cause pollution to the living environment during use. By implementing this standard, we can effectively regulate the mass of interior decoration materials, protect the health and safety of consumers, and promote the use of environmentally friendly coatings, which will help to promote the popularization of green building materials, improve indoor air mass, and meet the environmental protection requirements of sustainable development.
