How to improve the hardness of paint film for solid wood doors

With the increasing contraction of the home decoration market, the gradual subdivision of the furniture manufacturing industry has prompted the solid wood door industry to emerge. Large and small solid wood door factories have sprung up. Like other furniture products, the surface coating effect of the wooden door determines the quality of the product, which will directly affect the consumer's choice of wooden door products, so the surface coating is particularly important in the production process of wooden doors. In order to obtain a paint film of excellent quality, it is necessary to have a qualified surface treatment, a good quality paint, a correct coating process, and a familiar coating technique. At present, some manufacturers still use traditional furniture coatings (shoe paint) for solid wood door painting. We know that the main object of traditional furniture coatings is stickers and veneer products. For solid wood products such as wooden doors, it is very easy to appear. Hanging, bulging, sag and other paint diseases. To this end, a series of solid wood door special coatings have been developed for the wooden door market, which are mainly applied to solid wood door painting. Through many laboratory and on-site tests, it has been proved that the coating effectively solves the above problems, and the coating efficiency of the solid wood door is greatly improved, thereby obtaining a satisfactory coating effect.

Wooden door

The wooden door special series products are prepared by using modified wear-resistant resin and imported enhanced wear-resistant anti-sinking materials. Combined with the production site of solid wood doors, this series of products has convenient operation and construction. The superior performance is mainly reflected in: wear-resistant, anti-sagging, anti-drum sinking.

For the hardness of the paint film, only the office countertops used to use the hard furniture coating products. Now the consumer's hardness requirements for the solid wood door products are generally higher. In order to reduce the cost, individual wooden door manufacturers use paint products with lower quality grades. What's more, they change the combination of various components of the paint without authorization, and give up the curing agent matched by the paint manufacturer and use the curing agent with lower market price.

With the surge in international crude oil, there is a lot of pressure on the entire coatings industry. The price of chemical materials in the downstream has skyrocketed. TDI, solvent and phthalic anhydride are one price per day, which has enabled many curing agent manufacturers to reduce costs by reducing the solid content of curing agents. If such a curing agent is used, the optimum ratio of -OH and -NCO will not be obtained, and a small amount of resin will not be reacted, thereby affecting the hardness of the paint film. Therefore, we strongly recommend that the furniture manufacturers use the coatings and their auxiliary products.
