Aluminum silver paste is an indispensable metal pigment. Its main components are snow flake aluminum particles and petroleum solvents, which are in paste form. Its characteristic is that the surface of the aluminum sheet is smooth and smooth, the particle size distribution is concentrated, the shape is regular, and it has excellent light reflection ability and metallic luster. When mixed with the transparent color pigment, the paint film has obvious "effect of different colors", and the decorative effect is very gorgeous. Beautiful. Mainly used for automotive coatings, weak plastic coatings, metal industrial coatings, marine coatings, heat-resistant coatings, roof coatings. In the past two to three years, China's aluminum-silver paste products have begun to use the fine spherical aluminum powder as the raw material direction. There has been a major technological breakthrough in China, but its performance indicators, coating effects and other aspects have not been able to To reach the level of similar foreign products. Based on this situation, many domestic paint manufacturers are not clear on the selection and application of aluminum paste products, so first of all lead you to understand the classification of aluminum paste products. Aluminum silver paste is a very unique effect pigment, which can be divided into floating type, non-floating type, silver plating, imitation silver plating, young silver, silver flash silver, silver flash silver, silver flash silver, high flash silver, strong flash Silver and so on. It consists of a very smooth and extremely thin scaly structure, high particle size, high hiding power, strong coloring, clear color, fusion density and white light in one, can make the surface coating to produce elegant, soft and mirror-like Optical metal effect. Aluminum silver paste classification: All aluminum pigments can be divided into floating and non-floating two major categories. In the grinding process, the replacement of one fatty acid with another will give the aluminum pigment a completely different character and appearance. Because the appearance of each type of aluminum sheet is different from other types, the technical parameters that affect the product application formulation and end-use applications will also change depending on the desired effect. First, floating type In floating aluminum pigments, the aluminum flakes are oriented to form an opaque silver film near the surface of the paint film. This opaque property is the main factor that makes the floating aluminum pigment become an important functional raw material. The floating aluminum pigment is generally the main Used for roof coating with high protection requirements, maintenance, anti-corrosion coating, reflective coating, imitation plating coating, and commercial coating. The appearance of the floating aluminum pigment varies depending on the thickness of the particles, and can range from a rough, white appearance to dark, highly reflective or mirror-like effects. The coarse-layered floating aluminum pigments have a relatively low hiding power and a rougher structure, but can obtain a whiter, lighter coating. In contrast, fine-grained floating aluminum pigments have greater hiding power, a smoother structure and a highly reflective coating. Second, non-floating Non-floating aluminum paste has excellent coloring degree, and has strong hiding power. It is widely used in industrial coatings, auto parts coatings and decorative coatings; non-floating pigments are uniformly distributed in the entire film and are formed. The appearance of the coating is different from that of the floating aluminum pigment, and because it can be mixed with a variety of pigments for a variety of systems, it has a unique effect on industrial coatings. However, any pigment or dye must be transparent when used with non-leafing aluminum pigments in order to achieve a realistic metallic effect. Non-floating aluminum pigments are available in a wide variety of types, from low to high coloring power, from coarse to fine particles, and from pale to gray and soft. Non-leafing aluminum pigments have a variety of acid-resistant grades, which can reduce the influence of industrial smog, acid rain, and other adverse environments on the coated parts.
