Description and use of enamel NTs-132 - what is it

Today, in construction or repair, a great variety of all kinds of paints or enamels are used, thanks to which it is possible to protect and provide all kinds of improved decorative parameters. Thanks to the development of the latest technological solutions, a great variety of similar materials with various properties is being created. For example, NC-132 enamel has been very popular on the market for a very long time, and therefore we will consider its main technical parameters.

A little history and how it is deciphered, composition

The production process dates back to the seventies of the twentieth century, although even today this enamel is in no way inferior to its more modern counterparts.

This enamel is capable of forming a very, very homogeneous layer, which will be distinguished by its extraordinary smoothness, due to which the surfaces are provided with the highest level of reliability of protection, and from all kinds of influences on it.

It should be noted that initially enamels and paints differed only in the types of their diluting liquid. To dilute the enamels, volatile compositions with an organic base were used. But to dilute the paints, either drying oil was used, or the dilution process was carried out using ordinary water.

The letter designation NC indicates the fact that it belongs to a special nitrocellulose group, the basis for which is, strictly speaking, nitrocellulose itself.

It has a fibrous and very loose structure with a white color, somewhat reminiscent of ordinary cellulose, which is obtained by processing it using nitrogen.

Such enamel contains a variety of substances, both volatile and non-volatile. The first option is alkyd resins (No. 188 according to qualifications); colloxylin-nitrocellulose is also included, where the percentage of nitrogen content is 10.7-12.2, with the addition of various plasticizing additives and pigmenting particles.

But the non-volatile group of elements may differ for different types of enamel. It contains a forty percent solution of toluene, as well as butyl or ethyl alcohol, as well as the content of approximately 15 percent high-boiling active type solvents, and a slightly smaller amount of low-boiling ones. The second option is characterized by the addition of xylene instead of toluene, and the solvent content reaches thirty percent.

In order to increase the decorative characteristics, in order for the enamel to lay on the surface in a smooth and uniform layer, the process of adding additives against flotation processes, as well as additives that can increase the degree of fire resistance of the enamel, can be carried out.

In order to carry out the process of pigmentation of enamels, specialized pastes are used, which are first thoroughly crushed.

What are the main positive qualities and properties?

Among the positive qualities of NC-132 enamels today we can highlight the following, the most important and obvious:

• This enamel is characterized by the highest level of strength;
• It has high wear resistance parameters;
• It has a high level of elasticity, thanks to which it can easily be used on any shape with a wide variety of surface contours;
• It is distinguished by its high degree of water resistance, due to which it can be used for structures with high humidity or in outdoor conditions;
• Among other things, enamel is distinguished by the fact that it is very easy to care for; surfaces with such enamel are easy to wash using any household products;
• It should also be noted that surfaces with such enamel can be easily sanded or polished in order to give the surface a glossy shine, thereby significantly improving the decorative appearance of the surfaces;
• Coatings with this enamel do not fade when exposed to sunlight and do not react in any way to ultraviolet radiation;
• Among other things, enamel can withstand strong temperature changes;
• Enamel is distinguished by its economical use and has a very low price;
• It is distinguished by its long service life; if the process of double application of this enamel is carried out, the decorative characteristics will last for more than two years.

Advantages and disadvantages

Advantages and disadvantages

Elastic composition - this helps to paint surfaces that differ in different shapes and relief.

High resistance to moisture - helps to use the dye outdoors or in damp rooms.

High wear resistance - helps maintain the original appearance of the surface for 2 years.

Ease of maintenance - associated with the resistance of the coating to the influence of cleaning or detergents, including abrasives.

Resistance to ultraviolet radiation - the enamel does not fade in the sun and does not crack.

Resistance to extreme temperatures - this helps to use enamel in aggressive environments.

The balance of quality and price makes it possible to achieve excellent results for relatively little money.

A variety of shades simplifies the choice and makes it possible to implement any design solutions. After painting, the surfaces acquire a glossy shine.

Toxicity of the liquid - in many countries the substance is sold with restrictions.

The need to comply with safety rules - it is recommended to wear personal protective equipment when working with enamel. In this case, you need to use glasses, gloves, and a respirator.

Flammable characteristics - therefore, it is not recommended to paint surfaces near heating sources with electric heating elements and open fire.

What are the varieties?

Today we can distinguish two main varieties of this enamel, the technical characteristics of which are regulated by GOST 6631-74:

• NTs-132 “K”, this variety was specially developed so that it can be easily applied using a regular brush, it is distinguished by a certain level of its density; again, this type of enamel can be diluted with a solvent, making the consistency more liquid;
• NTs-132 “P” is more liquid in composition compared to the previous version, and is excellent for spraying with a spray bottle.

Material composition

Paint grade NTs-132 is produced in accordance with GOST 6631-74. The product is often called nitroenamel, because it contains a nitrocellulose component.

The composition of the paint is represented by the following substances:

• colloxylin varnish;
• alkyd resin;
• plasticizers;
• pigments of different colors;
• special fillers.

The product is available in two forms - NTs-132K and NTs-132P. The composition of the components in the enamels is the same, the only difference is in the relative viscosity and dry residue. The distinction is necessary because enamel marked “K” is intended to be applied by brush, while enamel marked “P” must be applied by spraying. The product is produced in cans of 0.8, 1.5 kg, in industrial containers.

What are the technical type parameters?

Among the main technical characteristics, the following can be noted:

• The enamel can be used at air temperatures ranging from minus 12 to plus 60 degrees Celsius;
• Already two hours after its application, the enamel becomes slightly sticky, and the complete drying of the enamel, after which the surfaces can be used with it, takes about a day;
• The film layer that is formed by this enamel after it dries is distinguished by a high level of smoothness, and does not form any various bumps, all kinds of dimples or spots;
• The characteristics of the enamel hardness level are approximately 0.15 cu, the process of establishing this parameter is carried out through the use of a special device;
• Thanks to the special one, it also becomes possible to measure the degree of impact resistance of the enamel layer, which is approximately 50 cu;
• The gloss level of the enamel surface is approximately 40-55 percent;
• The degree of presence of volatile substances in the composition can be determined by the color shade of the liquid; in black enamels their presence is the lowest - around 22-28 percent, in other color varieties it is around 29 percent;
• If the seal of the packaging of this enamel is not compromised in any way, then the shelf life of such enamel, provided it is properly stored, is one year.

Today, these enamels are produced in a wide variety of formats in cans - 0.7 or 1 kilogram, 1.7 kilogram. Large barrels of this enamel are also being produced, weighing 17 and 25 kilograms; such options are used for industrial purposes.

Specifications

Color shades

GOST also determines the color shades of enamel, and the variety of available color options is very large, so everyone can easily choose exactly the color shade that they need.

Light colors are produced in white, grey, cream beige tones and shades.

Dark ones are made in a wide variety of variations, for example, in tobacco and in many other color shades.

Among the natural color shades there are options for greenish or yellowish shades, bluish or pistachio tones.

Among other things, it is possible to create enamel in individual color shades according to the catalogue.

Color solutions for enamel NTs-132P

The color range is created in accordance with GOST. There is a large selection of colors: blue, black, white, yellow, grey, blue, green, red, orange. And a number of different tint options.

If a color is needed that is not presented in the palette, the manufacturer can produce it according to the Pantone catalog and others.

There is a large selection of colors.

What is the cost?

The enamel is sold quite liquid, and therefore, having carried out the process of opening the can of enamel, you can immediately begin painting work either with a spray, or with a brush, or with a roller. When the dilution process is to be carried out, solvents should be used.

To carry out the process of diluting the enamel, which is produced with the designation “K”, you should use a solvent numbered 649, for type “P” composition numbered 646, according to GOST number 18188. Again, the newly opened enamel must be thoroughly mixed so that the enamel has a homogeneous composition. Two hours after application, the surface becomes drier and harder, the temperature should be 20 degrees Celsius. Drying times may vary in other temperatures.

In most cases, the process of applying two layers of enamel or more is carried out in order to obtain a greater degree of coverage. The covering characteristics of the enamel determine how many grams should be applied per square meter. The degree of enamel consumption is mostly determined by color, for example, darker shades, such as black or dark blue-green, will require approximately 30 grams of enamel per square meter, but lighter shades, for example, white or beige, will require about 100 grams per square meter of surface.

To reduce the level of consumption of this enamel, it is necessary to carry out the process of preparing the surface to be painted in a high-quality manner. Corrosion and contamination should be thoroughly removed from metal surfaces. It is recommended to thoroughly dry and clean wooden surfaces, and to reduce absorbency, apply a primer or a thin layer of pre-diluted same enamel. Use primers like AK-070 or GF-021, FL-03K or VL-02.

Features of application technology

Nitroenamel is a toxic compound. She keeps the fire burning. Therefore, painting is carried out in a ventilated area, fire safety precautions are observed, and personal protective equipment (respirator, gloves) is worn.

• Using special solvents and washes, the old layer of enamel is removed from the surface. Rust and dirt are removed from metal;
• the dried metal surface is primed: VL (VL-023 primer for metal 40 kg + 8 kg acid thinner – 200 rubles); FL-03K (138 rubles per kg); GF-021 (86 rubles per kg); PF-020 (100 rubles per kg); GF-032GS (105 rubles per kg).

The wood is dried, sanded, dust removed, and primed.

Enamel, diluted in a 5:1 ratio with a solvent, is used as a primer: No. 646 for grade NTs-132P and No. 649 for grade “K.”

1. The surface of ferrous metals is not primed before painting.
2. The jar is opened, the mass is mixed, the film is removed, and the viscosity of the composition is established. Working viscosity according to VZ-4: for NTs-132K 30-60 s, diluted with solvent 649; for marking “P” 18-20 s, solvent 646 is used.
3. A two-layer enamel coating is applied. The second time the product is coated with enamel after 2-3 hours.
4. After 24 hours, the dried enamel can be polished so that the layer acquires a glossy shine.

What are the areas of use?

It should be noted that experts classify enamel as toxic and also fire hazardous, although such enamel is very, very popular today, and this is not at all surprising, given the high degree of its protective properties.

When applied to wooden surfaces in harsh climatic conditions, such enamel protects these surfaces from moisture. When painting metal surfaces or concrete products, they receive excellent protection against corrosive processes. Moreover, this is typical when using enamel in domestic and industrial conditions.

Today, this enamel is widely used in everyday life - for painting furniture or walls of houses, building facades or metal fences. Although when using this enamel, some toxic substances are released, therefore in some countries the use of such enamel is prohibited or has restrictions.

NTs-132 price

You can buy enamel in a price range from 90 to 200 rubles per kilogram; it is most profitable to buy paint in bulk and in large packages, 18 kilogram buckets and 50 kilogram drums. The price practically does not depend on the color. Prices cannot be lower than 80 rubles. The fact is that the components included in this nitro paint are quite expensive; replacing them will lead to the loss of the basic properties of NC enamels. Namely, quickly dry, polish and wash off with solvents 646, 647, 649. Recently, consumers have been complaining about the smell of “NTs-132”, which takes a long time to dissipate, the whole point is that some manufacturers are deceiving consumers under the brand NTs-132 GOST 6631- 74 sell a modified quick-drying PF, this is a completely different paint, with different properties. It costs less than 70 rubles per kilogram. You can distinguish NC paint from PF paint by smell. Real NC smells like solvent 646, the smell of real NC-132 disappears within half an hour.

If, after application and complete drying, solvent 646 is poured onto the coating, real NC will swell, and the modified PF will smear.
