Paint fumes are toxic, therefore, if painting is done in a room, it must be ventilated both during the work and for several hours after painting is completed. You should work with gloves and goggles to prevent the mixture from getting into your eyes and skin. After finishing dyeing, wash your face and hands thoroughly.

Peculiarities

NTs-132 enamel has been produced since the 70s of the last century, and it is difficult to believe that paint and varnish compositions have not yet been invented that would surpass it in their characteristics. Unlike paints, enamels form, after complete hardening, a smooth, uniform layer that protects the surface from various influences.

Initially, the main difference between enamel and paint was the type of thinning liquid. For enamel coatings, volatile compositions on an organic basis were used. In the case of paint, it could be drying oils or ordinary water. Over time, more and more water-dispersion enamels and acrylic-based coatings began to appear.

The letters NTs indicate that this enamel belongs to the group of nitrocellulose, that is, paints and varnishes made on the basis of nitrocellulose. This is a white fibrous structure, loose in appearance, reminiscent of ordinary cellulose and obtained from it by treatment with nitrogen.

The composition of NC-132 includes volatile and non-volatile parts. The first group includes alkyd resins (No188 according to the classification of resins), colloxylin-nitrocellulose with a nitrogen content of 10.7-12.2%, plasticizing additives and pigmenting particles. The non-volatile group differs for different types of enamels. It includes either 40% toluene, butyl or ethyl alcohol, about 15% active high-boiling solvents and slightly less low-boiling ones. In the second case, xylene is added instead of toluene, and solvents reach 30%. To improve decorative properties and smooth surface distribution, an anti-flotation additive and an additive to increase fire resistance can be added.

Manufacturers pay attention to the exceptional resistance of NC-132 enamel to various influences. In addition, the following positive qualities are noted:

In addition, the following positive qualities are noted:

• high strength and wear resistance;
• elastic structure suitable for use of any shape and surface shape;
• water resistance allows the enamel to be used in buildings with high humidity and outdoors;
• ease of care for surfaces coated with paints and varnishes - can be washed with any household products;

• the enamel layer can be ground and polished to give a glossy shine, which will further affect the decorative appearance of the products;
• the coating does not fade in the sun and is not susceptible to ultraviolet radiation;
• withstands strong temperature fluctuations;
• the material is economical and has a low price;
• long service life. When treating the surface with enamel in two layers in moderate climatic conditions, the coating can retain its decorative and quality features for up to two years.

Manufacturers

Factories producing NTs-132 enamel and other coatings are located in many cities in Russia.
NPO Ladoga has long been widely known and has two production facilities - in Omsk and in Crimea. Novosibirsk has developed a system of discounts for regular customers and a dealer program to facilitate the sale of its high-quality and budget products.

Belkolor LLC is popular among the average consumer. Buyers note the excellent coverage, bright colors and quick drying of NC-132 enamel from this manufacturer. The Belgorod enterprise has a twenty-year history; it has grown from a small workshop into an international brand with premium lines that are not inferior in quality to their foreign counterparts.

LMB gets good reviews. The availability of the product in a variety of hardware stores, combined with low price tags, makes it a worthy competitor in the paint and varnish market. The manufacturer is ready to confirm the quality of its products with many certificates.

The group manufactures its products in Canada, Switzerland, Poland and other European countries. Attractive prices are due to the presence of production facilities in our country. Enamels maintain the Western level of quality characteristics.

Continental LLC is a rapidly developing young company in the Russian construction market. But high quality standards, dynamic development and increased production capacity, combined with a huge range of products, allowed them to occupy their niche in the paint and coatings market. Enamels of the Krafor brand, produced by this manufacturer, are positioned as complying with GOST and sanitary-epidemiological standards. The company's factories are located in many cities in central Russia, in Udmurtia, as well as in the Czech Republic, Slovakia and Serbia.

Instructions for use of enamel NTs-132

Nitro enamels dry quickly, which must be taken into account when applying with a spray gun. At the same time, the paint sprayer allows you to obtain a high-quality surface when painting, but when working with another tool, drips are possible.

The declared consumption of nitro enamel is 100-120 g/m2.

Surface preparation before painting

Before applying enamel, it is imperative to prepare the surface. To do this, all dust, dirt, and debris are carefully removed, and the base is degreased. If paint is applied to a wooden surface, traces of rot and mold must be removed from it, and if a metal part is painted, rust and traces of corrosion must be removed. After cleaning, metal surfaces must be primed using one of the following mixtures: GF-020-021, FL-03K, GF-032.

It is also advisable to prime a wooden base; for this you can dilute the enamel with solvent 646, the proportion should be 5 to 1. It is not necessary to prime the wood. A layer of enamel is applied only to a completely clean and dry surface. If there is a thickened film on the paint, it must be removed and the mixture must be thoroughly mixed, and if the paint and varnish material is too thick, solvent 646 is used.

Scope of application

Although NC-132 enamel is a toxic and fire-hazardous material, due to its protective and elastic properties it has found wide application. Wooden products and structures located in harsh climates and high humidity will perfectly retain their original appearance. Metal surfaces and concrete bases will be reliably protected from corrosion. This is applicable both in domestic conditions and for processing materials in industrial production.

In the household, due to its excellent decorative properties, paints and varnishes can be used for painting furniture, walls and decorative items. Due to the low consumption, building facades and metal fences are also advantageous to treat with NTs-132. But the harmful substances released when working with nitro enamel have forced some countries around the world to limit the use of this product and even ban it completely.
