Three types of architectural coatings

Paint is an essential material in the decoration. Among them, there are three main types of interior wall coatings.

The first category is low-grade water-soluble paints.

It is prepared by dissolving polyvinyl alcohol in water and adding other additives such as pigments. The shortcoming of this kind of coating is that it is not resistant to water and alkali, and the coating is easy to peel off after being damp. It is a low-grade interior wall paint, and is mostly used for interior and interior of low-grade rooms or temporary rooms.

The second category is latex paint.

It is a kind of water-based medium, and the water resistance and weather resistance of the aqueous solution of acrylate, styrene-acrylate copolymer and vinyl acetate polymer are greatly improved compared with the first type, leaving no trace after wet scrubbing, and There are different decorative types such as flat light and high light, which are medium and high-grade paints. Although the price is more expensive, due to its excellent performance and decorative effects, the market share is increasing.

The third category is the colorful paint that is currently very popular.

The film-forming substance of the coating is nitrocellulose, which is dispersed in the water phase in the form of oil-in-water, and can be formed into a plurality of color patterns by one spray.

The interior and exterior latex paints have their own special requirements. The exterior latex paint is used to paint the facade of the building. Therefore, one of the most important indicators is anti-ultraviolet radiation, which is to achieve long-term exposure without discoloration.

The interior wall paint is used for interior wall slabs, and the UV protection requirements are much lower than the exterior wall paint. Interior wall latex paints require high scrub resistance.
