metal protection from high temperatures and corrosion

Typically, heat-resistant protective enamel on metal also possess anti-corrosion properties.It is known that the central heating radiators and other metal objects exposed to constant heat, it is impossible to paint the usual colors - such coverage does not last for a couple of months.Needed special heat-resistant coatings.They not only decorate the product operated in harsh environments, but also protect it significantly extending the service life.

course, heat-resistant inks are more expensive than usual.And not to make the wrong choice, it is necessary to determine in what temperature range, each of which will be operated.When heated to 100 ° C (in this mode radiators work) need formulations based on alkyd and acrylic resins.Heat to 200 ° C involves the use of hybrid materials - silicone epoxy and silicone acrylic.The interval 200-400 ° C requires one-component coatings based on ethyl silicate and silicone resins.Finally, at a temperature range of 400 ° C and higher should be applied one-component organopolysiloxane coating.The latter include, in particular, heat-resistant colored enamel "concerts" manufactured by Research and Production Enterprise "SPECTRUM".It can be used when heated to 750 ° C, making it suitable for the finishing of fireplace grates, barbecues, sauna stoves and other items that are directly in contact with fire.

However, the scope of the metal "concerts" is not limited.It is used for coloring concrete, brick and cement surfaces, not only exposed to heat.From a decorative point of view, "concerts" is also attractive because the forms clean, nice looking matte finish (black, chocolate, or terra cotta), but sometimes this is not enough.For those who wish to make a painted metal even more expressive, heat-resistant enamel "concerts-Patina" was developed.It can transform an ordinary fireplace screen, giving it the look of antiques from the old bronze or red copper.And even when heated to 700 ° C, the coating will not lose its beauty.

The number of heat-resistant paints stand out so-called blacksmith, before designated for forged products.As an example, we give priming enamel "concerts-Plast", which solve all complex tasks and problems associated with the metal.The coating protects the heating to 150 ° C, prevents moisture and aggressive chemicals, as well as effectively resists corrosion.

Reliable protection

guaranteed service life of the coating is at least 10 years.The latter is especially important for forged products.It will be a shame to see the balcony railings and garden furniture, which cost the owner a lot of money, rust and lose their appearance.And the process of priming enamel can not only new items, but also those already touched by rust.Soft scale before painting brushes, and a residual layer which can not be removed, converted enamel and metal fracture process stops.But of course, forged products, not only for paint protection.On the basis of the "concerts-Plast" can receive a variety of decorative finishes: matte, semi-matt, semi-gloss, "metallic", with hammer effect, more than 50 colors and shades.And if that's not enough, you can walk on top of the enamel as described above.

And finally a few words about how to paint the surface exposed to heat.First of all it should be roughened, and therefore the product to be processed by abrasion or sandblasting.Metal should be degreased with solvent of the same type, that is part of the chosen paint, the principle of "like with like".Apply the coating to be a very thin layer (less than 50 microns), and the best thing to do is spray.It is important to avoid neprokrasov.

Objects that are heated to 100 ° C, can be painted with spray and brush in two layers using a material of different colors - for example, first gray, then black.But a strong thermal effect necessary to paint products, and 2-3 layers only by the gun.
«As you know, heat-resistant enamel spray gun is better to put on the principle of" the higher the heat, the thinner the layer. "With regard to the patina, there are several techniques of surface finishing.The most popular - the so-called "dry brush".Before using "Tserta- patina" should be mixed thoroughly, then lightly dip it in a flat brush.Excess paint rub on the palette, and then flick go by the most protruding parts of the relief, not completely overlapping the previous coat of paint.If the area to be decorated of the object is large, and the work must be done quickly, can be worn on the arm cotton gloves, apply a little money for her and patinated surface, just touching it.Finally, you can use the spray gun.

Remember, the farther away from the sprayer will get off the subject, the more transparent patina.By combining paint and patina, you can achieve a variety of decorative effects.We are now very popular Smiths juicy pearl color combined with gold.In my opinion, extremely spectacular copper, is shaded a bit the same with gold.But there are many other options. "

Corrosion protection of metal

If the product is already affected by corrosion, it is necessary first of all to remove scale metal brush.Next, the surface of the coated rust converter, which neutralizes that could not be removed mechanically.Next layer - It is necessary for the ground in order to isolate the metal from contact with moisture and to ensure good adhesion of paint.Only after the soil has dried, you can start coloring.However, there are special enamel ( "3 in 1" priming enamel "concerts-Plast), combining and rust converter and primer and decorative coating.
