Problems solved by technology

[0002] Coatings are used in interior decoration, such as interior wall coatings, although they can make the interior walls beautiful and tidy, thereby making the living and living environment more comfortable, but many existing interior wall coatings tend to breed mold on the surface of the wall during use. Especially in humid areas such as coastal areas, molds can reproduce in large numbers under suitable conditions of 20-38°C and a relative humidity of about 85%, eroding the surface of buildings and destroying substrates. The main place for bacteria to grow; these molds, bacteria, and fungi destroy the beauty of the paint surface on the one hand, and seriously affect people's health on the other hand
