Explain the application of fluorescent pigments in coatings

Fluorescent pigment

    Fluorescent pigments can also be used in a variety of coatings such as textile printing pastes, traffic marking coatings, advertising coatings, toy coatings, bicycle baking varnishes, and various inks. The performance requirements of pigments for different coatings are different. At present, fluorescent pigment manufacturers in various countries have opened fluorescent pigments with different performances to meet market performance and price requirements, including solvent-resistant and solvent-resistant solvents. Resistant to strong solvent type, etc., the particle size of the three is generally relatively fine, but due to the different resin packaging and technical processes used, there are great differences in application. The solvent-resistant type is mainly used in water-soluble products, which can be dispersed in water, with low grade and narrow application range. The weak solvent-resistant type is mainly used in some low-grade inks and coatings, and the quality requirements are not high, and storage Long-term requirements; strong solvent-resistant quality, microsphere-encapsulated fluorescent pigment manufacturing process, excellent solvent resistance and bleed resistance, especially suitable for strong solvents and storage time requirements At the same time, due to its opacity, it has good hiding power and better weather resistance than ordinary fluorescent pigments.

    In the coatings industry, the selection of raw materials is also moving towards environmental protection. In the past, most of the domestic manufacturers used fluorescent pigments containing formaldehyde, but now they are not required to contain formaldehyde not only in export products but also in some domestic products. Therefore, more and more manufacturers choose fluorescent pigments that do not contain formaldehyde.
