What are the types and characteristics of coatings?

In home decoration, paint is one of the essential materials. Now there are many kinds of paints on the market, which makes many consumers very confused when purchasing. So, what kinds of paints are there? What are the characteristics? Let's introduce it to you. Let's get to know it together.

what kinds of coatings are there?

1. Water-soluble coatings

belong to low-grade products, which are made by dissolving polyvinyl alcohol in water and adding other additives such as pigments. At present, there are many brands of such coatings in the market, and the main products are 116, 117 and 813 interior wall coatings. These coatings have many defects, such as water resistance and alkali resistance, and the coatings are easy to peel off after being wetted, so they belong to low-grade interior wall decorative coatings products. However, this kind of coating still has many advantages, such as cheap price, non-toxic, odorless and convenient construction, and it is also quite convenient in the construction process. At present, the consumption is still the largest, accounting for about 51% of the market, and most of them are used for interior wall decoration of middle and low-grade rooms or temporary rooms.

2. Latex paint

belongs to the middle and high-grade paint material. It is made by using water as the medium, using the aqueous solution of acrylate, styrene-acrylate polymer and vinyl acetate polymer as the film-forming material, and adding a variety of auxiliary components. The film-forming material is insoluble in water, and the water resistance and weather resistance of the film are greatly improved compared with the first type. After wet scrubbing, there is no trace and smoothness. Although this kind of coating material is expensive, it occupies an increasing market share because of its excellent performance and decorative effect. A good latex coating has good water resistance, alkali resistance and washing resistance, and the coating will never peel off after being wetted. Generally speaking (under the same conditions of pigment, volume and concentration), styrene-acrylic latex paint has better water resistance, alkali resistance and scrubbing resistance than ethylene-propylene latex paint, and ethylene-propylene latex paint is better than polyvinyl acetate latex paint (commonly known as latex paint).

3. Colorful paints

Colorful paints are sought after in the market at present. The film-forming substance of this paint is nitrocellulose, which is dispersed in the water phase in the form of oil-in-water, and a variety of color patterns can be formed by spraying once; However, at present, a new type of coating material has appeared, which has delicate decorative effect, bright and clean, elegant and low price, but the construction technology is complicated and the wet rubbing resistance is poor.

what are the characteristics of coatings?

paint refers to a liquid or powdery material, which can be coated on the surface of an object through a specific construction process, and after drying and curing, it forms a solid coating film with certain strength and has special functions of protection, decoration or other:

1) protection: it protects the coated object from harmful substances and prolongs its service life;

2) Decorative: make the coated object more beautiful;

3) Special functions: for example, fluorescent paint for signs, others include flame retardant paint, anti-condensation paint and electrophoretic paint;

4) The properties of coatings can be divided into: the open-can appearance of coatings, low-temperature freezing and thawing resistance;
