In the process of producing melamine decorative paper, water stains sometimes appear on its surface. What is the reason for this? Let's take a look.

　　On the one hand, the reason for the water stains on the surface of melamine decorative paper may be due to the high moisture content of the substrate or the excessive residual volatile matter in the impregnated paper. On the other hand, it may also be caused by improper installation of the moisture content measuring instrument for impregnated paper. Another point is that if the edge temperature of the veneer is too low, or if the impregnated paper becomes damp during storage, it can also cause water marks on the melamine decorative paper.

　　So for the phenomenon of water stains on the surface of melamine decorative paper, it can be solved by adjusting the moisture content of the substrate or adjusting the drying process conditions of the impregnated paper.
