Embodiment Construction

[0007] During construction, an appropriate amount of diluent can be added to adjust the viscosity according to specific conditions.

[0008] The present invention mainly utilizes the film-forming substance (alkyd resin, modified alkyd resin or nitrocellulose ester, etc.), antibacterial agent, matting agent, butyl acetate, pigment (dye), leveling agent, defoamer in the formula Etc., during the coating process of wooden furniture, wooden floors and other wooden products, an antibacterial film is formed, thereby inhibiting and killing the bacteria growing on the surface. It has the advantages of high antibacterial efficiency, good decorative effect, and simple construction. It can be used for coating of modern wooden furniture and home decoration.

[0009] After testing, the antibacterial efficiency is 99.9%.

[0010] After testing, the content of harmful substances is as follows:

[0011] Volatile organic compound (VOC) 648g / L

[0012] Benzene Not detected

[0013] Sum of to...
