heat-resistant enamel - what is it?

You should start with a fact, how is this enamel.Its composition is somewhat more complicated than that of conventional paints are well known to us, which is not just used in the repair.Here more components, and much of their intricate formula.The basis is silicone varnish in any solvent, there are added various fillers and pigments, which form a slurry.From the combination of the latter two additional coating properties depend.

So, distinguish paints exclusively for black or non-ferrous metals, and have combined formulations.Enamel can be corrosion resistant or chemically.Also, let the ink resistant to water and weather conditions, it is usually used for painting or of heating oil and gas pipelines.The pigments responsible for the color, the most common heat-resistant enamel black and white is the most popular color, but not difficult to find exotic, if you need to be sure to withstand some colors, for example, in the room or bath.

heat-resistant enamel on metal designed primarily to protect against the damaging effects of high temperatures.In general, these paints can withstand from minus 50 to plus 600 degrees Celsius, but this range is distributed differently between different types of products, and not common to all, without exception.So we have to pick up items for your particular operating range.This exceptional ability to withstand the heat of the coating is a metal powder, usually aluminum, which allows you to evenly distribute the heat to the outside and out without disturbing the integrity of the parts and its coverage.

resistance to high temperatures there, but what the nature of this temperature is capable of withstanding the heat-resistant enamel?Here also there are nuances, because it may be hot from the open fire , wet or dry steam .It is for these criteria and shared by the paint, so it pays to pay attention to it coming into the store.

heat-resistant enamel on metal - ready to work

cleans the surface of the metal, which will be coated.Probably the main disadvantage is the old paint.It can be removed by special trains, even if it is in several layers, and the years of her more than anyone remembers.Rags just moistened with solvent and applied to the metal, after a couple of hours, the paint can be easily removed.It is also important to remove surface rust, dirt, dust, grease.Particularly relevant issue for the dirt and dust of the old batteries, the shape of which does not allow them to fully clean.But this time you have to thread the needle.

After cleaning the surface must be well degreased directly before working with any solvent (acetone, xylene, and others.).The paint should be mixed thoroughly, because during storage it has guaranteed a precipitate, which are collected the most valuable components for its heat resistance, so take the time and stir until complete disappearance of any deposits at the bottom of the jar.If the state is already finished paint is too thick you think (you can measure the viscosity of the devices), then it is diluted with solvent to the desired consistency.

heat-resistant enamel - paint correctly

Apply the paint can be any instrument, whether a brush, roller or spray gun, the main thing to observe safety measures, both personal and technical, because around solvents and varnishes, quite easily flammable liquids.You can work in a wide temperature range from minus 20 to plus 40 degrees Celsius.

When working protect the respiratory system, ensure that the room ventilation, avoid open flames.

If the work is carried out in a room where temperatures below zero, it is important sdela to avoid the frost formed on the surface so the paint does not tolerate moisture in any form, the more paint is warmer and it will melt the frost beneath them.

When paintable object has a complex shape and a lot of hard to reach places, then they are treated enamel (in the case of spray paint), then the entire surface is covered with a brush before staining.

enamel is applied in 2-3 layers (depending on the dyeing method, the layer thickness, the polymerization conditions and the further mode of operation).Naturally, between them it should dry out, so as not to cling to the brush with fresh paint.This may require different times depending on the temperature of the working area, on average, about 2 hours.After completing dyeing complete drying it is also dependent on the ambient temperature, typically on the packaging modes.

If the coating is to be used in the future in some extreme conditions, for example, in acids, the paint should be dried on a separate regime to its "temper".This is done at high temperature in the range of 250-400 degrees Celsius, while the drying time is reduced to 20 minutes.
