One type is the low-grade water-soluble coating, which is made by dissolving polyvinyl alcohol in water and adding other additives such as pigments. To improve its performance and reduce costs to take a variety of ways, many brands, the main products are 106,107,803 interior paint. The disadvantage of this coating is that it is not water-resistant and alkali-resistant, and the coating is easily peeled off after dampening. It is a low-grade interior wall coating and is suitable for general interior wall decoration.
This type of paint has the advantages of low price, non-toxic, odorless, and convenient construction. Dry wipe can not afford powder, because its film is water-soluble, so with a damp cloth after scrubbing always leave some traces, durability is not good, easy to yellow discoloration, but its cheap, the construction is also very convenient, The consumption is still the largest, accounting for about 50% of the market, and it is mostly used for the decoration of interior and interior walls in mid- and low-end homes or temporary residences.
The second type is latex paint, which is a kind of water-based medium and is made of an aqueous solution of acrylic esters, styrene-acrylic ester copolymers, and vinyl acetate polymers. It is made by adding a variety of auxiliary components. The film forming material is insoluble in water, and the water resistance and weather resistance of the coating film are greatly improved compared with the first type, and no trace is left after the wet scrubbing, and there are different decorative types such as plain light and high light. Due to its low color, the decorative effect is similar to that of 106 types. In fact, these two types of coatings are not a grade at all. They are medium-to-high-grade coatings. Although the prices are relatively expensive, due to their excellent performance and decorative effects, they occupy a larger and larger market share. A good latex paint layer has good water, alkali, and scrub resistance, and the coating will never peel off after it has been wet. In general (under the same conditions of pigment, volume, and concentration), styrene-acrylic emulsion paint is better than EPR paint in water resistance, alkali resistance, scrub resistance, and ethylene-propylene emulsion paint than polyvinyl acetate latex paint (known as latex paint). it is good.
The third category is a colorful paint that is currently very popular. The film-forming material of the paint is nitrocellulose, which is dispersed in the water phase in the form of oil-in-water. A single spray can form multiple color patterns.
In recent years, there has been a kind of imitation ceramic coating is the fourth category, its decorative effect is delicate, smooth, elegant, the price is not high, but the construction process is complex, poor resistance to wet rub.
