Certa heat-resistant enamel: features and specifications

If we use ordinary paints often, then this cannot be said about heat-resistant enamels. Heat-resistant paint is designed for coloring non-ferrous and ferrous metals, the material may have a combined composition. This type of dye protects metal surfaces and other types of coating from high temperatures and corrosive environments.

Conventional paints can not boast of heat resistance, so there is an increased demand for enamels from Finnish companies Tikkurila, High Heat Black Paint, British manufacturers Rustins or for Russian products Certa, which has high technical characteristics.

Certa heat-resistant enamels are designed for painting metal surfaces., equipment, heating, oil and gas pipelines, furnaces and other surfaces.

Comparing with the composition of conventional paint, which is used during repair work, it will be more difficult for heat-resistant analogues because of the greater number of components. The basis of heat-resistant paints contains a special suspension consisting of silicone lacquer in a solvent with the addition of filler and pigment. Heat-resistant paints are resistant to high humidity. This type of enamel can withstand temperatures from -50 degrees, up to +650 degrees Celsius.

Popular paints from Russian manufacturers have been applied in many industries. Most often they are used in the chemical industry and mechanical engineering, they cover parts of furnace and heating devices.

This type of paint has a certain specificity:

• contains a toxic solvent;
• before starting the surface is prepared;
• dry enamel Certa at high temperatures.

It should be borne in mind that in industrial conditions Certa dries for 45-50 minutes, in home use without toxic accelerators, such time will not be enough. After staining to carry out installation or transportation of equipment should be only after three days. Painting metal parts, apply 2-3 cross layers.

The most popular can be called heat-resistant paint on metal. Certa to 900 degrees. Pigment is responsible for the saturation of the color of paintwork materials, you can often find white or black enamel, but you can also find other shades if you need to withstand a certain color range.

The most commonly used black paint, black semi-gloss, silver-gray and graphite. Other colors are chosen, among them yellow, copper, red, brown, blue, blue and green. In addition, there are unique new items - gold and copper color.

This paint will protect the material from corrosion, fire and moisture. Anticorrosion paint goes down easily, it is applied to a metal, concrete and cement surface, after painting it dries within half an hour.After drying, the enamel forms a uniform film without wrinkles and irregularities. If the paint is applied to the weld or other hard-to-reach places, they are painted with a brush, holding it several times in this area.

LKM produced in various versions, there can be added nickel, chromium or aluminum powder. The company "Spectrum" produces Certa enamel in packs of 400 and 800 grams, as well as 520 ml aerosols to cover rough cast iron, forged and cast steel surfaces. After testing with paint, the shelf life of the coating was confirmed to 25 years.

Attention should be paid to the novelty - it is enamel Certa patinawhich is used for decoration of metal products. Patina allows you to give products the effect of aging.

Putting a patina on the surface of the metal, you should:

• stir the paint;
• dip the brush;
• rub the excess paint;
• easily touching the brush, you should walk through the selected areas without overlapping the previous layer.

To prepare the surface for painting, it should be cleaned of dirt, remove rust, old paint, oil or grease. You can carry out mechanical or manual cleaning.Surface treatment is carried out to degrees St 3 or SA2-SA2.5. The letters St mean that it is cleaned manually or mechanically, using a brush. All rust before cleaning should be scraped off the surfaces, remove residual oil and dirt. After all the pollution will be removed, carry out dedusting.

Blast cleaning is indicated by the letters SA. The degree SA2-SA2.5 implies a very thorough surface cleaning. During the inspection should not be revealed residues of oils, rust, paint and other contaminants.

After the surface has been completely cleaned, it should be degreased with a solvent; Solvent or Xylene may be suitable for this. Degrease the surface before work. Do not keep the product after processing without degreasing for more than six hours on the street or more than a day indoors.

After opening the can, the enamel should be thoroughly stirred until the sediment disappears and wait ten minutes until the bubbles disappear. The enamel viscosity can be measured with a special instrument viscosity meter VZ-246, it is designed to determine the conditional indicator, that is, the time of expiry of the paint.Using "Xylene" or "Solvent", it is possible to dilute the paint to the desired consistency, but not more than 30%. At the end of the work the jar is tightly closed and left for storage.

Paint is applied to the surface with a roller or brush. It should be applied in a thin layer, it depends on how well the silicone film adheres to the metal.

When using Certa spray paint in a can, a very even coating is obtained, but many toxic substances get into the air. It is better to use this option for coloring not very large items, such as a brazier, barbecue or silencer. It is important to carry out work in the fresh air, using means to protect against toxic substances.

Many heat resistant materials do not require pretreatment. The consumption of coatings will depend on the conditions under which it is used. When painting the walls of the chimney should be applied two layers of enamel,when painting braziers or barbecue, one is enough. On the surface of brick or plaster put 2-3 thick layers.

During the work with Certa enamel it is necessary to consider that in its structure there are aromatic solvents ("Xylol" and "Solvent") which, if used incorrectly, may cause harm to human health.

When working with paintwork materials, you should follow safety rules.

• Enamel should be applied in fresh air or in well ventilated areas.
• When painting, workers should wear rubber gloves and protective paste; be sure to wear a gas and dust respirator.
• Enamel refers to flammable liquids, so it is important to adhere to the rules of fire safety. Fire extinguishers should be at the work site, smoking is prohibited on the site.
• In case of fire, you need to be able to use means to extinguish a fire, the object should be water, sand, etc.

The shelf life of Certa inks at temperatures from -60 to +40 degrees Celsius is 18 months. These types of paints are stored in a tightly closed jar in places where there is no direct sun on them.
