What are the types of lacquer paints? What are the types of paints and coatings

The main purpose of putty powder is to fill the pores of the construction surface and correct the curve deviation of the construction surface, so as to lay a good foundation for obtaining a uniform and smooth paint surface. Putty is divided into oily putty and water-based putty, which are used for paint and latex paint construction respectively. There are two types of putty: finished putty and on-site putty.

The products in the coatings market are broadly divided into:

Interior wall paints for interior wall decoration.

Exterior wall paints for exterior wall decoration.

Wood paint, which is used for wood surface decoration, can be subdivided into wood paint for wood floors and other surfaces.

Lacquer for metal, used for the decoration of metal surfaces.

Floor paint for interior and exterior cement floor decoration.

Classification of paints.

1) According to the form of coatings, it can be divided into water-based coatings, solvent-based coatings, powder coatings, high-solid coatings, etc.;

2) According to the construction method, it can be divided into brush coating, spraying coating, roller coating, dipping coating, electrophoretic coating, etc.;

3) According to the construction process, it can be divided into primer, middle coat, paint (two primers), top coat, overshadow paint, etc.;

4) According to the function, it can be divided into decorative coatings, anti-corrosion coatings, conductive coatings, anti-rust coatings, high-temperature resistant coatings, temperature indicator coatings, heat insulation coatings, etc.

5) According to the use, it can be divided into architectural coatings, canned coatings, automotive coatings, aircraft coatings, home appliance coatings, wood coatings, bridge coatings, plastic coatings, paper coatings, etc.

Characteristics of the paint.

Workability: The performance index of the paint when it is used, and a good product should be easy to paint. Inferior products have a dry feeling when applied, and it is not easy to apply them smoothly.

Low temperature stability: It is the performance of whether the coating can be stably stored at low temperatures. High-quality paints remain unchanged after low-temperature storage, while low-quality paints will lead to deterioration and cannot be used.

Appearance of the coating film: The appearance of the paint film after drying, a good appearance should be smooth, without bubbles, sagging, serious painting marks and other phenomena.

Contrast: The ability of the paint to cover the substrate. The higher the value, the greater the coverage.

Alkali resistance: Walls are generally alkaline, so the coatings used for walls must have a certain ability to resist the damage of alkaline substances. Paints that are not resistant to alkaline substances may become discolored, powdered, and peeled.

Scrubbing resistance: The ability of the paint to withstand scrubbing. When it is required to scrub with water, the paint will not peel off in large quantities and expose the substrate.

Paints and paints.

There is actually no difference between paint and paint, which can be understood as two names for the same thing. Chinese consumers are accustomed to calling water-based paints paints and oil-based paints paints, which is not accurate.

Latex paint. Latex paint is divided into types of paints, paints, and latex paints.

The primer plays a closed, isolating role, and the effect of moisture and mildew protection also depends on the primer.

The primer is divided from the function of the coating. Topcoat and primer. Latex paints include latex paints, primers and latex paints, topcoats. Paint is also divided into undersides. The primer of latex paint is alkali and moisture-resistant, which increases the combination of topcoat and base layer. Because it is recommended to use a primer.

The function of the topcoat is to decorate and be beautiful; Latex paint is the name for the two together.

It's too much to know what you want.

There are two major classifications, one is water-based paint and the other is oil-based paint. According to the classification of the substrate, there are many kinds, and the paints include phenolic paint, alkyd paint, nitro paint, resin paint, and polyurethane paint. Paint usually refers to latex paint, like exterior paint is the category of latex paint.

1. According to the form of paint (powder, liquid).

2. According to the film-forming mechanism, it is divided into **chemical shape and non-transformation type).

3. According to the construction method (brush, roller, spray, dipping, drenching, electrophoresis) 4, according to the drying method (room temperature drying, drying, moisture curing, steam curing, radiation energy curing) 5, according to the use of the level (primer, middle paint, topcoat, putty, etc.) 6, according to the appearance of the coating film (varnish, color paint; matte, flat, matte, high-gloss; Hammered lacquer, embossed lacquer.

1. Anti-curing coating. This coating is highly resistant to water, heat and cold, and wear-resistant and hard, but contains formaldehyde, which is more harmful.

2. Nitro coatings. The coating is simple to apply, and the work efficiency is high, and the impact on the environment is very small, but the ridge is not hard enough.

3. Polyurethane coatings. High stability, full gloss, high transparency, but poor construction performance, in general, is the most common furniture paint.

4. Unsaturated resin potato coating. Strong hardness, heat resistance, acid and alkali resistance are very good, but the construction process is complex, and improper operation is easy to cause potential safety hazards.

5. Ultraviolet curing coatings. A kind of environmentally friendly paint with high hardness and transparency, and low cost, convenient construction and high work efficiency.
