Author:    Date:2017/10/17 16:11:22

Fluorocarbon topcoat can calmly deal with all kinds of corrosive environment, especially for anti-corrosion performance, decorative effect of pressure when the strict selection of this series of anti-corrosion products, is inherent in these advantages, widely used in external walls , Architectural decoration, steel corrosion, seaside corrosion, etc., in the selection of paint, we must carefully choose a reasonable package of paint in order to ensure that the superb coating effect. Outdoor steel corrosion, the use of different environments use anti-corrosion paint performance is very different, with the use of paint with the different environment has also been a corresponding change. Ordinary anti-corrosion rust, can be used with epoxy iron red primer or epoxy red Dan primer, according to the construction environment in the middle of the epoxy paint to increase the performance of the middle; for severe anti-corrosion, will be zinc-rich primer rendering, Epoxy cloud iron intermediate paint to increase the anti-rust performance, while providing excellent adhesion for the finish, the surface is naturally fluorocarbon topcoat as a corridor of environmental protection. Building exterior anticorrosion, usually concrete or cement base, no rust, but need to be able to effectively cover the base, to ensure smooth and no leakage, commonly used with a closed primer + thick film in the paint + fluoride Topcoat. This combination can not only guarantee the base of the formation of no leakage, but also can provide excellent anti-corrosion and decorative performance, can be described as two birds with one stone. For some aluminum and stainless steel metal, because some of the characteristics of the metal, so the general will be phosphating primer primer, and then supporting the use of fluorocarbon topcoat can be. If there is no problem with the re-coating of the fluorocarbon paint, it is not enough to just test the dryness of the front paint, and it is necessary to pay more attention to the following points. In order to ensure that the fluorocarbon paint does not appear when the construction defects, before painting to ensure that the former road paint fully dry, but this is only one of them, we have to ensure that the following construction.

1, in order to enhance the adhesion, the need for the front paint paint the surface of the rough roughening treatment, the general use of about 400 mesh sandpaper, to avoid omission and treatment is not in place.

2, the use of electric equipment for a large area of roughing, you can quickly improve the efficiency, due to film coarsening will affect the fluorocarbon coating overlay adhesion and weather resistance.

3, in the coated fluorocarbon anticorrosive paint, because the first understanding of the former paint in the end for what kind of anti-corrosion paint, to ensure that there will be no incompatibility between the coating phenomenon. On the former Road paint do not understand, please refer to: Fluorocarbon paint brush before the old coating to determine the method , airless spray when the gun movement speed, to ensure that spray Of the film to achieve the desired thickness. Disposable film thickness should not be too thick should not be too thin. In order to avoid problems such as sagging, spray gun can be sprayed when spray gun.

Any construction problems can be contacted at any time
