The T/JCS 02-2018 standard specifies the technical requirements for diatomaceous earth interior-wall water-based paints. As the main component of Coatings, diatomaceous earth has good hygroscopicity, vapor transmission rate and antibacterial performance, making the Coatings have excellent environmental friendliness and health performance, especially suitable for indoor wall paintings. The standard specifies in detail the composition, physical and chemical performance, construction methods and testing requirements of Coatings to ensure that Coatings can provide excellent adhesion, durability and anti-pollution ability during use. The standard also emphasizes the low VOC emissions of water-based paints, which meets the requirements of green environmental protection and promotes the sustainable development of the Coatings industry. The standard provides a technical basis for manufacturers to promote the application of diatomaceous earth water-based paints in interior decoration.
