What are the types of elastic latex paints for exterior walls? What are the skills for purchasing elastic latex paint for exterior walls?

In modern home decoration design, wall decoration is the key part of the whole interior decoration, and the wall even determines the whole interior decoration effect, which requires the use of wall finishes. Nowadays, the elastic latex paint for exterior walls is deeply loved by the majority of owners. Next, Bian Xiao will introduce the related contents of elastic latex paint for external walls, and interested friends will continue to read on.

What are the types of elastic latex paints for exterior walls?

1, emulsion elastic coating

Emulsion elastic coating mainly takes polymer synthetic resin emulsion as the main film-forming substance, which is called emulsion exterior wall coating. According to the manufacturing method of emulsion, it can be divided into two types: one is emulsion directly synthesized by emulsion polymerization; The other is an emulsion prepared by emulsification with polymer synthetic resin. According to the texture of the coating, it can be divided into latex paint (thin latex paint), thick paint and colored sand wall finish.

2. Solvent-based elastic coatings

Solvent-based elastic coating is a volatile coating made of polymer synthetic resin as the main film-forming substance, organic solvent as diluent, and a certain amount of pigments, fillers and additives, which are mixed, stirred, dissolved and ground. Special agent. After the elastic coating is applied to the outer wall surface, the film-forming material and other non-volatile components together form a uniform and continuous film. Solvent-based elastic coatings have good hardness, luster, water resistance, acid and alkali resistance, good weather resistance and pollution resistance.

3. Inorganic polymer elastic coating

Inorganic polymer building elastic coating is a newly developed building coating. There are two kinds of alkali metal silicates and silica sols widely used in buildings. Organic polymer architectural coatings usually have some shortcomings such as poor aging resistance, poor heat resistance and low surface hardness. Inorganic molecular coatings have good properties in these aspects, such as good aging resistance, high temperature resistance, corrosion resistance and durability. The coating has high hardness and good wear resistance. If the material selection is reasonable, the water resistance is good and the raw materials are widely used. Because of its low price, it has been widely concerned at home and abroad and developed rapidly.

2. What are the purchasing skills of elastic latex paint for exterior walls?

1. The most important thing to buy elastic latex paint for exterior walls is to look at its environmental indicators, that is, the content of volatile organic compounds (VOC). The national standard stipulates that the VOC content of latex paint per liter shall not exceed 200 grams.

2. Fineness of coating particles: put a small amount of coating into a glass of clear water. After stirring, the water is clearer, the particles are independent, not sticky, the particle size is uniform and the coating quality is good. Environmental protection paint should be water-based, non-toxic and tasteless. It is best not to buy flavored paint, and the additives are also environmentally friendly.

3. Mix the elastic coating with the wooden stick, and then select it with the wooden stick. When the high-quality elastic paint flows downward, it will form a fan shape. Touch by hand, the real elastic paint should be smooth and delicate. Brush it on the wall, dry it, and then wipe it with a wet cloth. The original color is as bright as the new one, and the defective product will fade.

The above is all the contents of the elastic latex paint for exterior walls introduced by Bian Xiao.
