    Core tip: Introduction: Pigment and filler are divided into three steps: wetting, crushing and stabilizing Wetting and dispersing are often used as one word in coatings Wetting usually refers to the expansion of liquid on the solid surface due to the effect of surface tension When the liquid or air with low surface tension contacts with another liquid or solid with high surface tension, such expansion will occur; in this case, it refers to the process in which the air or water adsorbed on the surface of pigment and filler is replaced by the dispersing medium Wetting agent is a substance that can make solid materials more easily wetted by water By reducing the surface tension or interface tension, water can develop Paint agent, top 10 Chinese wall paint brands Recommended introduction: interior wall paint and exterior wall paint can achieve beautiful, clean and pleasant effects, but the effects in different environments are different, so the color of the paint will be different There are ten brands of Chinese paint, ten brands of global paint, ten brands of Chinese wall paint, and ten brands of Chinese paint, Famous trademark of Chinese paint and coating In private rooms, most of us choose according to our own personality, personal hobbies and living habits The younger generation will choose the interior wall paint with rich colors and bright colors, while the older ones will have some working experience Paint Home News: Introduction: pigment and filler in the pulping time for wetting, grinding, stability three steps, wetting and dispersion is often used as a word in paint Wetting usually refers to the expansion of liquid on the solid surface due to the effect of surface tension When the liquid or air with low surface tension contacts with another liquid or solid with high surface tension, such expansion will occur; in this case, it refers to the process in which the air or water adsorbed on the surface of pigment and filler is replaced by the dispersing medium Wetting agent is a substance that can make solid materials more easily wetted by water By reducing the surface tension or interfacial tension, water can spread on the surface of solid materials, or penetrate into the surface of solid materials, and wet the solid materials Wetting agent is the adhesion of liquid on solid surface Its essence is the combination of solid gas and liquid Hydropalat 875, a wetting agent for aqueous system, is a kind of surfactant with excellent performance It can reduce the surface tension strongly in aqueous solution, enhance the wetting of the coating on the substrate, and improve the adhesion Meanwhile, it can help the coating to level effectively, eliminate the surface unevenness of the coating, and improve the floating color in the tank in the specific color matching paint Technical specifications: advantages: ① hydropalat 875 is used as a wetting agent in the water-based coating system Because of its excellent wetting characteristics, it is especially suitable for difficult to wet substrates such as plastic, metal surface, cellulose film, aluminum film, plastic foil, silicon treated paper and glass, which can enhance the adhesion to the substrate Hydropalat 875 can also be used as an emulsifier for various monomer emulsion polymerization, and Hydropalat 875 stable polymer dispersions have superior properties and excellent wetting properties If the dispersions are required to have excellent wettability and mechanical stability at the same time, hydropalat 875 is recommended to be used in combination with high ethoxylated nonionic surfactants such as dispo nil ls, Ta or NP Adding 0.2% hydropalat 875 will help to solve the problem of water separation Application: the dosage is usually 0.1% - 1.0% The exact dosage should be determined by experiment Hydropalat 875 is slightly soluble in water and can be diluted to a certain concentration with water When the active substance is about 50%, it may produce liquid crystalline gel phase Storage: it is recommended to store at room temperature to avoid heating or freezing It is recommended to add it after grinding under strong agitation Packaging: 300 kg / barrel, 200 kg / barrel; customized packaging according to customers Home of coatings is specialized in coatings, diatom mud, paint coating, coating technology, fire retardant coating news and coating, diatom mud, paint coating, coating technology, fire retardant coating decoration knowledge and decoration renderings,
