The main components of varnish during the processing and production process are resin, solvent, oil and other main raw materials. Formaldehyde is mainly added to the adhesive of the board. The reason why it appears in the paint surface is that the wood coated with varnish will be sealed inside and the formaldehyde gas will evaporate from the paint surface. So it is ultimately a problem with the wood.

Second, to see whether the varnish is toxic, we mainly look at the volatile substances after use. As we all know, no matter what kind of paint it is, there will be a smell during the use process, and this smell mainly comes from the volatilization of the paint agent. Currently, the paint solvent on the market is generally benzene, which is divided into high benzene content and low benzene content. Benzene is harmful to the human body.
