Iron or steel structures or metal parts that are to be exposed to high temperaturesThe paint must be treated with heat-resistant paint. The application of this type of paint helps to protect the parts and not to deteriorate them.
To protect the iron and steel surfaces when exposed to very high temperaturesThere are several systems. The most important thing to consider is the maximum temperature to which the surface or the part will be exposed. It is important to know that most of the paints that are manufactured resist between 0 and 700ºC, approximately. In addition, the range of colors is limited, and you can not choose the one you want, because from 150 º C there are few pigments that resist in perfect conditions. Therefore, this information must be known before knowing what type of paint or color to choose.
Types of heat-resistant paints
Anti-heat paints are one of the most effective treatments for use on steel or iron surfaces exposed to high temperatures. Within them, in Lecker's we manufacture two types.
First, Primalcoat 200. This is a antiheat painting aluminum colored. This type resists between 200 - 300ºC, with high chemical resistance. In addition, it has the particularity with respect to other brands that, once dry, when the pieces are handled, neither the hands nor the piece are stained. Therefore it is an advantage and an added value as far as the finish is concerned. This type of paint dries quickly and has a high anti-corrosive power. It is very resistant to the exterior, offering a uniform and elegant finish.
In Lecker's we also manufacture Primalcoat 600. This type of antiheat paint is manufactured with a combination of silicone resins. It is aluminium coloured and resists up to 600 - 700ºC. It is very suitable for painting burners, exhaust pipes, ovens, steam pipes, chimneys, etc. It has great anticorrosive power and high resistance to the exterior.
How to work with antiheat paint
To treat surfaces with our antiheat paints (regardless of whether it is with Primalcoat 200 or 600) it is done in the same way:
We will start by degreasing the iron or steel surface we want to protect. To do this, we clean it thoroughly with our DIRT OUT degreaser or with cleaning solvent 05003, removing all dirt, oils and grease. Once clean and dry, it is time to apply a first coat to cover the piece. Let it dry for 15 minutes and apply a second coat. At this point, the anti-caloric paint should be left to dry for 3 to 6 hours. After that time we have the piece ready to use.
It is important to know that the parts should never be primed before applying the antiheat paint and that this should be applied in thin layers, as this is the best way for the heat to dissipate. It should also be considered that only Primalcoat should be used and that large thicknesses should not be applied, but that with 15 microns there is enough.
