What is color paste? Benzidine yellow, red pigment, permanent orange and other pigments and water can be mixed? Color paste is not benzidine yellow, pigment red, permanent orange and other pigments and water simple mixing can be, but by the pigment or pigment and filler dispersed in the paint made of semi-products. To pure oil as the adhesive called oily paste. Resin paint for the adhesive called resin paste. With water as a medium to add surfactant dispersed pigment slurry is called aqueous paste. Due to the large variety of paints, there are many types of pastes. In order to make benzidine yellow, red pigment, permanent orange and other pigments dispersed better in the paint, often in the manufacturing process, add a small amount of surfactant, plus zinc naphthenate and so on. The choice of paste is the most important factor to ensure the long-term consistency of the exterior paint. The color and weather resistance of the colored paint for the external wall is not only the type and amount of the emulsion, the variety and amount of the pigment, the titanium dioxide and the filler, Coating additives and the amount of choice, the color of their own light and weather resistance, temperature resistance and resistance to chemical resistance is the key.

  The colorant itself, these properties, mainly depends on the pigment structure and surface treatment. In general, inorganic pigments in the above properties are superior to organic pigments, but the color is not as bright and bright as organic pigments, tinting strength is relatively low, but inorganic pigments rely on the entire molecule hair color, so the color of light and weather resistance, temperature resistance is very good. Traditional organic pigments differ greatly from inorganic pigments in this performance, while copper phthalocyanines (blue and green) and high-performance organic pigments (1,4-diketopyrrolopyrrole (DPP) Pigment, quinacridone pigments, anthraquinone heterocyclic structure type pigments, etc.) has excellent light and weather resistance, temperature resistance and resistance to chemical media and migration, basically comparable with inorganic pigments.

  However, since organic pigments rely on chromophore groups to color, their properties are directly affected by the chromogenic group structure. If the chromophore structure chemical bond can be large, high chemical inertness is good, the corresponding physical and chemical properties of stability, light and weather will naturally be excellent. And paste is the inorganic and high-grade organic pigments surface wrapping once again to make it not only easy to use, pollution is small, more importantly, its exhibition color performance has greatly improved.
