Common knowledge of coating: composition of coating

The core tip: the coating mainly consists of four parts: film-forming material, pigment, solvent and auxiliary agent Film forming substance is the basis of coating, which plays a decisive role in the performance of coating and film It has the function of bonding other components in coating to form film There are many kinds of materials that can be used as film-forming materials, and resin is mainly used in the contemporary coating industry Resin is a kind of organic substance in amorphous state, usually refers to polymer In the past, natural resin was used as film-forming material in coatings, but in modern times, synthetic resin was widely used, such as alkyd resin, acrylic resin, chlorinated rubber resin and ring Paint knowledge how about Akzo Nobel Powder Coating Recommended introduction: powder coating is a kind of coating with different form from general coating, which is in powder form It is a new type of coating, because of its own advantages and more and more known by people Let's introduce Akzo Nobel Powder coating Akzo Nobel Powder coating is a cost-effective coating solution, which can be applied to different kinds of products After the treatment of static electricity and fire baking, a tough and durable coating surface will be formed, with the least impact on the environment Since the introduction of this technology, powder coating has been able to continue to maintain the Coating home news: coating mainly consists of four parts: film-forming materials, pigments, solvents, additives Film forming substance is the basis of coating, which plays a decisive role in the performance of coating and film It has the function of bonding other components in coating to form film There are many kinds of materials that can be used as film-forming materials, and resin is mainly used in the contemporary coating industry Resin is a kind of organic substance in amorphous state, usually refers to polymer In the past, natural resin was used as film-forming material in coatings, while in modern times, synthetic resin was widely used, such as alkyd resin, acrylic resin, chlorinated rubber resin, epoxy resin, etc Pigment is a main component of colored paint The pigment makes the film present color, and the film has the ability to cover the coated object, so as to play its decorative and protective role Some pigments can also provide such properties as: improving the mechanical properties of paint film, improving the durability of paint film, providing anti-corrosion, conductive, flame retardant and so on Pigments can be divided into natural pigments and synthetic pigments according to their sources, inorganic pigments and organic pigments according to their chemical composition, and coloring pigments, physical pigments and special pigments according to their functions in coatings Inorganic pigments are the most widely used in coatings, and synthetic pigments are also widely used The solvent can dissolve or disperse the film-forming substances in the paint into a uniform liquid state, so as to facilitate the construction of the film, and the substances that can volatilize from the paint film to the atmosphere after the construction, in principle, the solvent does not constitute the film, nor should it be retained in the film Many chemicals including water, inorganic compounds and organic compounds can be used as solvent components of coatings In some modern coatings, some compounds which can not only dissolve or disperse film-forming substances into liquid state, but also react with film-forming substances to form new substances in the process of film-forming during construction and remain in the paint film are developed and applied, which are called reactive active agents or active diluents Some of the solvents are added during coating manufacturing, and some are added during coating construction Auxiliary agent is also called auxiliary material component of coating, but it can not form coating independently It can exist in coating as a component of coating after coating The function of additives is to improve the performance of a specific aspect of the coating or film Different types of coatings need to use different additives; even if the same type of coating needs to use different additives due to different purposes, methods or performance requirements; a variety of different additives can be used in a coating to play different roles 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,
