Paint is a viscous suspension composed of base materials, pigments, fillers, solvents and additives. It is coated on the surface of the object to form a tough coating film, which plays a role in decoration and protection of the object.
The pigment in the paint has a certain hiding power, it can not only cover the original color of the object to be coated, but also give the coating film a bright color to achieve the effect of beauty and decoration. At the same time, the pigment and the fixing agent are tightly combined and integrated, which can enhance the mechanical strength and adhesion of the coating film, prevent cracks, and can increase the thickness of the coating film, prevent the penetration of ultraviolet rays and moisture, and improve the aging resistance of the coating film. Service life.
Regardless of solvent-based or water-based coatings, if titanium dioxide is used, its role is not only to cover and decorate, but also to improve the physical and chemical properties of the coating, enhance chemical stability, and even improve hiding power, decolorization power, and corrosion resistance. , Light resistance, weather resistance, enhance the mechanical strength and adhesion of the paint film, prevent cracks, prevent the penetration of ultraviolet rays and moisture, thereby delaying aging and extending the life of the paint film. At the same time, it can save materials and increase varieties.
