Nitrocellulose enamel NTs-132: technical characteristics and properties
In order to protect and give Various decorative characteristics for surfaces in the field of construction and repair are used by many paints and enamels.
Modern developments have led to the fact that there are many paints and varnishes with a variety of properties. Nitrocellulose enamel NTs-132 has been known in the construction market for a long time, but it will not lose popularity yet.
The answer to the question why it will be in great demand will be the information in the article.
Enamel number 132 has been produced since the 1970s and it is hard to believe that at the moment, paint and varnish compositions have not yet been invented that would surpassed it in their own characteristics.
In contrast to the same paints, the enamels will form, after complete curing, a homogeneous smooth layer that protects the surface from all kinds of influences. Initially, the main difference between paint and enamel was the type of thinning fluid. For enamel paints and varnishes, volatile organic compounds are used, and in the case of paint, this can be drying oil or the simplest water. Over time, much more water-dispersion enamels and acrylic-based paints and varnishes began to appear.
It is interesting that the letters NTs indicate that such enamel can belong to the group of nitrocellulose, which means that they are made on the basis of nitrocellulose of paint and varnish material.
This fibrous structure is white, loose in appearance, and also strongly resembles the most common cellulose and is obtained from it through nitrogen treatment. A composition such as No. 132 includes non-volatile and volatile parts. The second group includes resins of the alkyd type (No. 188 according to the classification of resins), colloxylin - nitrocelluloses with a nitrogen content of 10.
8 to 12.2%, as well as plasticizing additives and pigment-type particles.
The non-volatile group will differ for different types of enamels. It includes either 40% - toluene, ethyl alcohol or butyl alcohol, and about 15% more active high-boiling type solvents and slightly less low-boiling ones. In the second case, xylene is added instead of toluene, and the solvent compositions reach 30%.
In order to enhance the decorative properties, the ideal distribution on the wall, an additive to improve the fire resistance and flotation can be added.
Pigment the compositions by means of special pastes, which should be kneaded in the grinding devices. Manufacturers will pay attention to the exceptional resistance of the enamel product to various influences.
In addition, the following positive qualities can be noted:
Now let's look at the types of enamel.
Technical parameters and types of enamel NTs-132 will be regulated in accordance with GOST 6631 -74. A couple of types of paints and varnishes can be distinguished:
And now let's take a closer look at the technical characteristics:
Enamel is also produced in most convenient formats, cans, ranging from 0.7 kg, as well as 1 and 1.7 kg, and for large barrels it is 17 and 25 kg, there are containers and more.
In addition, the color scale is regulated by GOST. The choice of shades is quite large and makes it possible to choose the desired color for each type of finish.
Light colors are represented by plain white, two types of cream and light gray, and light beige.The dark range includes dark blue-green, tobacco, gray-blue, dark gray, grayish-green, protective and black. If you need a brighter surface finish, shades such as red, brown, orange-brown and golden brown are suitable. Natural colors are represented by calm green-beige light shades, pistachio, light grayish-green, pale green and grayish-blue. If you need one more shade, you can also custom-manufacture according to the RAL catalog.
Enamels are already on sale in ready-made liquid form for use. After opening the can, you will immediately begin finishing work with the spray gun, rollers and brushes. If there is a need to dilute the product, this should be done using solvents.
For enamel type 132 "K" composition 649 should be used, and for 132 "P" version 646 according to GOST 18188. In any case, the composition in a newly opened jar should be immediately stirred in order to give it homogeneous consistency.
The time to achieve dryness and hardness is about a couple of hours at a temperature of +20 degrees. If the thermometer readings in the room / outdoors are different, then the final result may be obtained in a different time frame.
It is customary to apply two or more layers of NTs-132 enamel, the technical characteristics of which are such that the optimal hiding power is achieved from just two layers. The flow rate is determined by this very characteristic. This indicator will indicate how many grams of the composition are required to be applied per square meter.
Most of all, the color of the composition will affect the consumption. Dark shades are black, dark blue-green requires 0.03 kg per square, and light shades are white and cream about 0.1 kg per square.
Note that in order to reduce enamel consumption, more attention should be paid to surface preparation prior to painting.
Metal substrates should be cleaned of corrosion, rusty marks and dirt.
Surfaces for wood materials should be thoroughly dried and sanded for improved adhesion. To reduce the absorbency of naturally occurring material, it is best to use a primer or a thin coat of similarly diluted enamel. Primer compounds are suitable, or rather, AK-070, GF-021, VL-02 and FL-03K. If there are greasy spots on the surface, it is imperative to treat them with special compounds.
If the base was covered with oil paint, then it should be removed without a trace in advance.
Although enamel No. 132 belongs to toxic and fire hazardous materials, it has acquired incredible application due to its protective and elastic properties. Wood products, structures that are located in a harsh climate, high humidity will perfectly preserve their original appearance. Metal surfaces and concrete bases will be reliably protected from corrosion.
This applies both to domestic conditions and to the processing of materials for industrial production. For household use, due to the excellent decorative properties of the paint and varnish material, it can be used to paint furniture, decor and walls. Facades of buildings and metal fences due to low consumption will be beneficial to treat the surface with enamel. But the harmful substances that are released when working with nitro enamel have forced certain countries of the world to restrict the use of such a product, as well as completely ban it.
Due to the above characteristics and toxicity when using enamels, some recommendations should be followed.
Store materials in a specially designated area away from flammable materials, as well as direct sunlight. When applying the composition, rubber gloves and respiratory masks should be used to ensure that vapors enter the lungs. Protection must be provided for the eyes, in the form of special glasses. The use of special clothing is also required. It is better to carry out work in a place with the possibility of ventilation, and painting should be carried out in the absence of open fire.
At the end of the work, wash your hands and face with soapy water.
Factories that make this enamel and other paints and varnishes are located in a large number of cities in Russia. Long known NPO "Lagoda" which has a couple of factories in Crimea and Omsk.
