Coating = The paint? The two are actually quite different!
In decorating classics regular meeting hears paint and coating these words, to many people character, the distinction of these two is very not apparent,many people think that paint is polyurea coating
, but is it really so? Is paint really coating? Maybe the answer will surprise you. Let's check it out.
1. Definition of coatings and paints
Coating is a kind of solid coating film used for the surface of an object. It has the functions of protection, decoration, insulation and anticorrosion. Generally, it can be divided into liquid and solid forms.
Paint is to point to be medium with organic solvent or tall solid, the general term of solvent-free oily lacquer.
2. The difference between coating and paint
A. Most of the former marine boat paint
were made from vegetable oil, so they were called paints, but synthetic resin replaced vegetable oil completely now, and its apparent characteristic is liquid, cannot cover solid coating, name with paint again improper, changed coating instead.
B. say simply, coating includes the paint of solid powder coating and liquid paint, but paint can be the paint of liquid only, cannot be equated with coating, coating one word can cover all sorts of products of industry.
C. Water-based coatings and powder coatings are widely used in the market,water-paint architectural coatings account for about 38% of the total amount of coatings in China.But water borne coating and paint have essential distinction on chemical property, the property difference of the product is very big also, so this kind of material also is called coating.Water paint and paint should be listed as two different series of liquid coatings.
Therefore, the coating can be divided into three categories: paint, waterproof coating
, powder coating; Paints (fluid, mobile coatings) include paints and water paints.
3. The difference between water paint and paint
Water paint is a liquid paint that uses water as a thinner.The difference between water paint and traditional paint is that water paint does not need to add any curing agent or thinner. It only needs to be mixed with water, so it does not contain harmful substances such as formaldehyde, benzene and xylene, thus eliminating the possibility of air pollution. At present, in developed countries such as Europe and the United States, it has basically replaced oil paint, and the penetration rate has reached more than 90%. It is a relatively environmentally friendly paint.
4. The difference between water-based paint and latex paint
Any coating that uses water as a solvent or as a dispersion medium can be called a water-based paint, water-based coatings include water-soluble coatings, water-reducible coatings, and water-dispersible coatings (latex coatings) 3 types.
Latex paint is also known as synthetic resin emulsion coating, is a kind of organic coating, is a synthetic resin emulsion as the base material,then add a kind of water-based paint prepared from pigments, fillers and various additives.Latex paint is only one kind of water-based paint. The range of water paint is wider, there are metal paint, wood paint and so on.
