Domestic most coil coatings with rutile type titanium pigment, but as a result of rutile type titanium pigment is expensive, so that sharp state type titanium pigment has certain potential in the application of coil coatings, and prospects. Based on performance and composition of coil coatings, this paper discusses the role of titanium pigment in paint, as well as the sharp state type titanium pigment quality indicators for the influence of coil coatings applied, through the analysis, find out the sharp titanium type titanium pigment in the production process to strengthen the quality control and technical improvement measures, to achieve sharp titanium type titanium pigment used in coil coating.
Sharp titanium type titanium pigment is a kind of fine white powder paint, has a good ability of light scattering and good whiteness, high tinting strength, hiding power is strong, strong at the same time has high chemical stability and good weather resistance, avirulent insipidity, no stimulation to the human body, widely used in many industrial fields, such as coating, plastic, paper making and printing ink, etc. Type at present, the sharp titanium titanium dioxide titanium dioxide domestic enterprises mainly produce low blocking time sharp state type titanium dioxide, rutile type titanium pigment mainly rely on imports. Because the rutile type titanium pigment refractive index and the weathering resistance is higher than sharp state type, and wide application range.
