Due to the chemical composition of the wood and the particularity of the wood fiber, if it is not handled properly, the water-based paint film will be damaged. Wood is composed of cellulose and a small amount of gum, resin (rosin), pigment, tannin and the like. Although the amount of gum, resin, pigment, tannin, etc. is small, it has a large negative impact on the properties of the coating (mainly...
