The cause and solution of cracking of furniture paint film

China Paint Online News Information
furniture paint film cracking is a more common phenomenon in summer furniture paint construction, if this problem occurs we should first understand the cause of furniture paint film cracking, and then specific measures to solve.The reason for the cracking of the furniture lacquer film:Because in the process of construction, the lacquer coating film is too thick, resulting in the surface drying film fast, while the thick inner layer is dry slowly, directly causing the primer cracking and other phenomena. At the same time, we should pay attention to the quality of the plate, it is recommended to buy stable plate.at the same time the moisture content of wood is too high, after painting the wood deformation caused the paint film cracking; Primer one-time thick coating, because the adhesion and flexibility of the paint film is decreased with the increase of the thickness of the film, when the thickness of the paint film exceeds a certain limit, the paint film performance will appear very brittle; Do not match the construction instructions with furniture paint, especially curing agent added excessive, pu paint will be excessive cross-linking reaction, paint film will become very brittle, easy to crack.the solution of cracking the furniture paint film:should do the final test before construction, to ensure that the water content of wood is less than 12% before the construction; At the same time to avoid primer one-time thick coating, as far as possible thin coating many times; It is best not to use wet touch wet process, if you must choose, you need to master the thickness and number of each layer, up to two times is appropriate. In addition, the paint should also be in accordance with the construction instructions for painting.in daily life, we should also pay attention to furniture paint film to avoid contact with high concentrations of chemical reagents, such as hydrochloric acid, thinners, etc., so as not to damage the paint film.
