What is the main ingredient of paints and coatings

The main ingredient of paint master:
(1) Oil: including drying and semi-drying oil, is one of the main film-forming substances.

(2) resin: include natural resins and synthetic resins, also part of the main film-forming substances.

(3) pigments: including coloring pigments, extender pigments and anti-rust paint, specific varieties quite numerous, as a secondary film-forming substances.

(4) The thin material: including solvents and thinners used to dissolve the above substances and preparations consistency for auxiliary film-forming substances.

(5) Accessories: Includes driers, curing agents, plasticizers, moisture agent. Also belong to the auxiliary film-forming substances.

Decorative coatings composed mainly consists of three parts: the main film materials: adhesives and also called a fixing agent, is the basis of the composition of the coating. Minor film material: also form part of the film, but it can not leave the matter alone constitute the main film coating. Auxiliary film-forming materials: including solvents and auxiliary materials. The former, such as gasoline, smoke oil, turpentine, benzene, ethyl acetate, acetone, etc.; the latter, such as curing agents, emulsifiers, thickeners, driers, wetting agents, dispersing agents, defoamers, initiator, catalyst , stabilizers, anti-aging agents, antifreeze and the like.
Coating main components: a film-forming material is the main component of the coating film, including fats, oils processed products, cellulose derivatives, natural resins and synthetic resins. Film-forming materials also include non-volatile portion of the reactive diluent, which is firmly attached to the coating material is coated on the major surface to form a continuous film coating constitutes the basis to determine the basic properties of the coating;
2 additives such as defoamers, leveling agents, there are some special functional additives, such as substrate wetting agents. These additives are generally not formed, but the process of the base material forming the coating film and durability plays an important role;
3 pigments are generally divided into two types, one for the coloring pigments, common titanium dioxide, chrome yellow, etc., as well as kind of an extender pigment, it is often said fillers, such as calcium carbonate, talc;
4 the solvent include hydrocarbon solvents (mineral spirits, kerosene, gasoline, benzene, toluene, xylene, etc.), alcohols, ethers, ketones and esters. The main role of solvent and water is to make the film-forming material to form a viscous liquid dispersion. It helps some of the construction and improvement of the coating
Performance.
According to the main film-forming material used in the coating The coating can be classified into oil-based paint, fiber coatings, synthetic coatings and inorganic coatings; trait of the coating or film can be divided into a solution, emulsion, sol, powder, light, extinction and colorful paint Art and so on.
