What are the basic components of architectural coatings?

Paint is mainly composed of four parts: the membrane material, pigments, solvents, additives. Film material - is the base paint, coatings and coating it to play a decisive role in the performance, it has the function of other components in the adhesive coating forming a coating film. Substance use varieties can be used as material for a lot of film, contemporary paint industry mainly uses resin. Resin is an amorphous state of the organic materials, usually polymers. In the past, the use of natural resin as film coating material, is widely used in modern synthetic resins, for example: alkyd resins, acrylic resins, chlorinated rubber resins, epoxy resins and the like. Pigments - are a major component of the color coating (paint) a. Presents the coating color pigments, the coating has the ability to cover the object to be coated to play its decoration and protection. Some pigments also provide services such as: improving the mechanical properties of the film, to improve the durability of the film, provides corrosion resistance, electrical conductivity, flame-retardant properties. Pigments can be divided by source natural pigments and synthetic pigments; according to the chemical composition divided into inorganic and organic pigments; according to the role in the coating can be divided into, coloring pigments, extender pigments and specialty paint. Paint is the most used inorganic pigments, synthetic pigments are very extensive, and now the development of organic pigments quickly. Solvent - paint film material can be dissolved or dispersed liquid uniform in order to facilitate construction of a film, from the film and then when the construction of the volatile substances to the atmosphere, in principle, does not constitute a coating solvent, nor should be retained in the coating film. Many chemicals, including water, inorganic compounds and organic compounds can be used as a solvent component of the coating. Some modern paint both the development and application of some of the film material is dissolved or dispersed in a liquid state, but while remaining compounds in the film forming process of the construction of the film-forming chemical reactions occur with the formation of new substances, is called reactive agent or reactive diluent. Some solvents in paint manufacturing when joined, some added in the coating. Additives - also known as secondary coating material components, but it can not independently form a coating film, which after coating film formation may be present in the coating film as a component of the coating film. The role of additives on the performance of a particular aspect of the paint or coating to improve the role play. Different varieties require different effect coating additives; even if the same type of coating, because the purpose of their use, or performance requirements of the different methods, which require the use of different additives; one coating may be used in a variety of different promoters agents, in order to play their different roles. (Aids classification: (1) play a role in the production process for coating additives, such as defoamers, wetting agents, dispersants and emulsifier (2) to play a role in the paint during storage aids, such as anti-settling agent stabilizers, anti-skinning agents. (3) construction work on the paint additives, such as leveling agents, defoamers, driers, anti-sagging agents. (4) for the film on performance effect of additives, such as plasticizers, matting agents, flame retardants, fungicides and the like.)
