What is the difference between polyester paint and nitro paint? What are the pros and cons?

Nowadays, there are so many types of paints on the market that it is easy for people to choose from them, but each paint has its own special effect and uses are different. Today we will introduce you to two new paints: polyester paint and nitro paint.

Let's take a look. Nitro paint is a relatively common wood and decoration coating, made of nitrocellulose, alkyd resin, pigments, plasticizers and organic solvents. It is mainly used for wood and furniture coating, home decoration, general decorative coating, metal coating, general cement coating, etc.

The decorative effect is good, the construction is simple, the drying is rapid, the requirements for the coating environment are not high, and it has good hardness and brightness. Polyester paint, also known as unsaturated polyester paint, is a multi-component paint, which is a thick paint made of polyester resin as the main film-forming material. The paint film of polyester paint is plump, and the layer is thick and hard.

Polyester paint also has varnish varieties, called polyester varnish. Polyester paints need to be cured during the application process, and the amount of these hardeners accounts for one-third of the total amount of paint. These hardeners, also known as hardeners, are mainly composed of TDI (toluenediisocyanate).

Summary. Nitro paint is a type of paint. The main differences are that the properties are different, the classification is different, and the functions are different, as follows:

First, the nature is different.

1. Nitro paint.

Nitro paint is a relatively common coating for wood and decoration.

What is Nitro Paint? How is it different from ordinary paint?

Nitro paint is a type of paint. The main difference is that the properties are different, the classification is different, and the functions are different, as follows: 1. The properties are different 1. Nitro paint Nitro paint is a relatively common wood and decoration coating.

PU paint refurbishment spray nitro white, after a long time, the nitro paint film will not fall off.

Hello. No, it won't.

Is the adhesion of nitro paint good.

That's right, the adhesion is very good, my previous unit used nitro paint, painted the floor, and the fence, and the effect was very good.

Because the nitro paint, adjusted well, you can adjust the thickness of the paint, pro.

Nitro paint is currently a more common coating for wood and decoration. The advantages are that the decoration effect is better, the construction is simple, the drying is rapid, the requirements for the coating environment are not high, it has good hardness and brightness, it is not easy to appear paint film defects, and it is easy to repair. The disadvantage is that the solid content is low, and more construction roads are required to achieve better results; The durability is not very good, especially the internal nitro paint, its gloss and color retention is not good, and it is easy to have disadvantages such as loss of light, cracking, and discoloration after a long time; The protective effect of the paint film is not good, and it is not resistant to organic solvents, heat and corrosion.

Nitro paint is commonly known as spray paint, also called"Dry paint";"Lak"Or lak paint, which is made of nitrocellulose as the main body, with synthetic resin plasticizers and pigments, etc., dissolved in organic solvents, and made by grinding. Advantage 1Dry quickly.

2.The paint film is silky. 3.

The luster is soft. Cons 1Poor weather resistance.

2.Poor fullness of the paint film. 3.

Poor leveling. 4. It is not heat-resistant, not scald-resistant.

Nitro paint is a type of paint. The main differences are that the properties are different, the classification is different, and the functions are different, as follows:

First, the nature is different.

1. Nitro paint.

Nitro paint is a relatively common coating for wood and decoration.

2. Paint. Paint refers to a chemical mixture coating that can be firmly covered on the surface of an object for protection, decoration, signs and other special purposes.

Second, the classification is different.

1. Nitro paint.

Nitro paint can be divided into four categories: external varnish, internal varnish, wood varnish and various colors of magnetic varnish.

2. Paint. Coatings: A general term for a class of liquid or solid materials that can form a solid coating film with protection, decoration or special properties (such as insulation, anti-corrosion, signs, etc.) applied to the surface of an object. Including oil (sexual) paint, water-based paint, wood paint, powder coating, wood wax oil.

Paints: oil-based paints that use organic solvents as a medium or high solids and solvent-free.

Third, the function is different.

1. Nitro paint.

1) Nitro external varnish: It can be used for the finishing of outdoor metal and wood surfaces.

2) Nitro internal varnish: It can be used as the coating of indoor metal and wood surfaces.

3) Nitro wood varnish: can only be used for the finishing of indoor wooden surfaces.

4) All kinds of nitroalkyd enamel: suitable for indoor and outdoor metal and wood surface coating.

2. Paint. Protection function: anti-corrosion, waterproof, oil-proof, chemical-resistant, light-resistant, temperature-resistant, etc. Coating the surface of the object to form a protective film can prevent or delay the occurrence and development of these damages, so that the service life of various materials can be extended.

Decorative function: Objects of different materials are coated with paint, which can get a colorful and colorful appearance, which plays a role in beautifying the human living environment.

Other features. Marking, anti-fouling, insulation, etc. For example, electrical insulation, conduction, shielding electromagnetic waves, mildew, sterilization, insecticide, high temperature resistance, heat preservation, temperature indication and temperature marking, prevention of flame retardation, ablation and heat insulation.

Nitro paint is made of nitrocellulose as the main body, with synthetic resins, plasticizers and pigments, etc., dissolved in organic solvents, grinded, and naturally volatilized and dried.

Advantages: fast drying speed, easy to renovate and repair, can be coated with dry and dry, no grinding between layers, simple and convenient proportional construction, and good hand feel. Due to its low solids content (20%), it is ideal for open coating.

Among the furniture products exported to Europe and the United States, the so-called American-style painting, the use of NC paint is more prominent.

Disadvantages: Due to the low solid content (20%), it is difficult to make a coating film with good fullness and high gloss, and the number of construction passes, poor chemical resistance and solvent resistance, easy to whiten under the condition of high temperature and high humidity, and low hardness of the paint film.

composition.

This product is a nitro external enamel made of synthetic resin, nitrocellulose, solvents, additives and pigments.

Characteristics. Nitro enamel has the characteristics of fast drying of the paint film, smooth and bright, good hardness, good combination, polishing and waxing, increasing decoration and prolonging the life of the paint film.

Uses. It is suitable for the protection and decoration of automobiles, machine tools, machinery and equipment, daily hardware, power tools, furniture, home decoration and various metal and non-metal devices.

Technical requirements. Methods for testing the technical indicators of the project.

Construction references. 1. The paint is coated on the surface of the sprayed primer, and the primer has a good bond, so it is advisable to choose the primer matched with the nitro paint, and it is recommended to use various colors of nitro primer, putty, putty, etc.

2. Stir the paint evenly before use, if there are coarse particles or mechanical impurities, it must be filtered before use.

3. The construction is mainly spraying, with a supporting nitro thinner, in a place with high humidity, if the paint film is found to be whitish, nitro paint moisture-proof agent can be appropriately added.

4. During construction, the interval between two spraying should be about 20 minutes.

5. The amount of aluminum powder paint is best mixed according to demand.

Nitro paint, also known as NC, is generally used in paint PU, the cost of its composition is not the same, nitro paint is generally more environmentally friendly, but the effect of PU paint will be better than it, nitro paint is generally suitable for American coating.

The main film-forming material of nitro paint is mainly nitrocellulose, combined with alkyd resin, modified rosin resin, acrylic resin, amino resin and other soft and hard resins. Generally, plasticizers such as dibutyl phthalate, dioctyl ester, and oxidized castor oil are also added. The solvents mainly include true solvents such as esters, ketones, alcohol ethers, co-solvents such as alcohols, and diluents such as benzene.

Nitro paint is mainly used for wood and furniture coating, home decoration, general decorative coating, metal coating, general cement coating, etc.

The difference from other paints is that the film-forming substances of the paint are different.
