The relationship and difference between paint, coating and resin

In life we often hear the words paint, paint, resin, whether you are confused about the relationship between them, silly can not tell. After reading this article, you will find out the difference and meaning of the three nouns.
the relationship between paint and paint, resin can be listed as ≥ paint >

. Resin is the smallest of the three units, as a base in paint and coating formulations, while coatings contain paints in the widest range.
first to understand the resin, natural resins are derived from the resin from plants, such as pine, amber, insect gum and so on, pure resin appearance is generally colorless transparent. In natural environments, due to the existence of many impurities, and affected by sun and air oxidation, so the colors vary, most of the yellow or dark red-brown. Natural resins were limited by yield and performance and gradually gave way to synthetic resins for industrial production. Synthetic resin production is controllable, the performance is easy to adjust, and the purity is high, with the development of science and technology, more and more types of synthetic resin, its performance is constantly improving.
resin is widely used, thanks to its good physical and chemical properties, treated resin has excellent elasticity, insulation, water isolation, oil resistance, acid and alkali resistance, pressure resistance, wear resistance, high temperature resistance and so on, from the initial crafts, to the later application to all aspects of human society. For example, there are umbrellas, gloves, clothes, soles and so on in the lives of residents. Cars on the road, submarines in the water, planes in the sky, rockets in space... But there are some problems, some of the resins are liquid, as thin as water; some are solid, as hard as stone; and some are semi-solid, soft, like rubber mud. Problems can arise when stored or used. Plus when the resin is used alone, a lot of performance does not go up, performance is greatly reduced. Therefore, some resins have to use liquid oil solvents for dissolution (oil solvents and water are similar, are liquid, can dissolve certain substances, but water does not contain C molecules, and organic solvents contain C, most of which are incompatible with water, if mixed together will become a non-continuous phase, you can see oil droplets floating in the water.) ), add fillers and pigments and other additives as needed to improve stretch strength, bending strength, heat resistance and heat resistance, etc., which becomes paint.
paint refers to the organic solvent as a medium or high solid, solvent-free oily paint.
paint contains resins, additives, pigments, solvents, organic solvents are basically toxic. Therefore, in order to ensure the safety of the general public, the state has clear limits on the content of various types of paint solvents.
was previously processed from vegetable oils and natural resins to be commonly called paint. With the development of industry, more and more varieties of coatings, quality and performance continue to improve, many new coatings no longer contain oil components. The term paint is not accurate enough. Therefore, the various materials used for coating surfaces are now collectively referred to as coatings, paint is only one of the coatings.
As for the coating, which contains the four main components of paint, but some solid resins do not need to add oil solvents, can be used in a powder state, this part of the non-organic oil solvent resin after mixing other additives and pigments, it is called powder coating, distinguished from paint.
simply put, coatings can cover solid powder coatings and liquid paints, but paint can only be liquid paint, can not be equated with coatings, coatings can cover all kinds of products in the industry.
Water-based coatings and powder coatings are now widely used on the market, but water-based coatings and paints have essential differences in chemical properties, and the nature of products vary widely, so these materials are also known as coatings. Therefore, coatings can be divided into three categories: oil (sex) paint, water-based paint, powder paint.
in short, the generalization is that coatings contain paints and powder coatings, and resins are only a base material in paint and powder coating formulations.
main components of paint include the following five parts:
(1) oil: including dry oil and semi-dry oil, is one of the main film-forming substances.
(2) resins: including natural and artificial resins, are also part of the main film-forming substances.
(3) pigments: including coloring pigments, body pigments and rust-proof pigments, the specific variety is quite a variety of secondary film-forming substances.
(4) dilute material: including solvents and thinners, used to dissolve the above-mentioned substances and toner consistency, for auxiliary film-forming substances.
(5) accessories: including drying agents, curing agents, plasticizers, moisture inhibitors. It is also an auxiliary film-forming substance.
the composition of decorative coatings is mainly composed of three parts:
main film-forming substances: also known as adhesives and fixants, is the basis of the composition of the coating.
secondary film-forming substance: it is also an integral part of the coating film, but it cannot leave the main film-forming substance and form a coating film alone.
auxiliary film-forming substances: including solvents and auxiliary materials. The former such as gasoline, flue oil, pine perfume, benzene, ethyl acetate, etc., the latter such as curing agents, emulsifiers, adhesives, deo dryers, moisturizers, dispersants, defrosts, triggers, catalysts, stabilizers, anti-aging agents, antifreeze agents, etc.
