Crosslinked solidified fluorocarbon coating

Crosslinked solidified fluorocarbon coating,On some performance although not as good as teflon, poly (vinylidene fluoride and other heat curing film coating, but because of its molecular structure was introduced in paraffin base, hydroxyl and carboxyl functional groups, make its have the soluble in room temperature, can be cured, such as performance, thus expanded the scope of its application field and use, especially make the excellent performance of the coating for large-scale application in engineering to become a reality. Compared to other coatings, it has the following advantages:

(1) ultra-long weatherability, artificial aging time over 5000 hours, durable longevity over 20 years, is 3 ~ 10 times the traditional coating.

(2) good erosion resistance to chemical media, coating with high crosslinking density, very low coating porosity, permeability resistance is excellent, almost all of the acid, alkali, organic solvent, etc all can't through, 4 ~ 6 times that of the traditional coating;

(3) good anti-pollution. Crosslinked coating, which is formed by the type of fluorocarbon coatings with low surface energy, low friction coefficient and the characteristics of the non-stick dust contamination is hard to attach, easy cleaning, can be bright as new after rain wash;

(4) the flame retardant is good. Crosslinking type of fluorocarbon coating has the flame retardancy, the limiting oxygen index up to 95%, flame temperature up to 300 ℃;

(5) adaptability. Crosslinking type of fluorocarbon coating can in - 40 ~ 100 ℃ temperature range of normal use, can resist cold summer and dry-wet alternate complex environment;

(6) the coating has high adhesion strength. Such as carboxyl was introduced to the fluorine resin molecules in active group, and of different base with a strong adhesion, adopt different bottom, intermediate paint can form various adhesion strong supporting system;

(7)Construction performance is good. As with other solvent coatings, it can be coated with brush, spray, roll, etc.

(8) ornamental excellence. Crosslinking type of fluorocarbon excellent decorative can the architectural design ideas and the perfect implementation provides conditions, nobility is elegant, the film surface fine and smooth, colour and lustre is uniform, as many as thousands of colors.

In addition, it also has good antistatic and radiation resistance.

Can be seen from in, although the molecular structure to still belong to the polyurethane type of fluorocarbon paint, it and the aliphatic polyurethane coating has good anti-corrosion performance, but both on the protective life is quite a gap, crosslinking type of fluorocarbon lacquer is far superior to the performance of polyurethane coating performance. This paper analyzes the differences in theory, experiment and engineering practice.

Crosslinking type of fluorocarbon compared with conventional anticorrosive coatings, although the unit price is higher, but as a result of excellent anti-corrosion performance, greatly extended the use fixed number of year, reducing the number of maintenance, from the comprehensive benefit evaluation, select the crosslinking type of fluorocarbon coating of steel structure and equipment is suitable for outdoor. In this paper, the economic evaluation of the synthetic fluorocarbon and the commonly used anticorrosive coatings is shown in table 11.

Despite the higher cost of coating supporting system using fluorocarbon coatings for the first time, but its anti-corrosion life as high as more than 20 years, and the other coatings in 20 years to repair many times, from coating cost (labor, maintenance shutdown losses haven't calculation), with fluorocarbon lacquer is economic and reasonable supporting system.

Above all, crosslinking was far superior to the performance of type of fluorocarbon acrylic polyurethane paint, its comprehensive performance is the best, for now, is used in steel structure and concrete exposed to atmospheric environment the best paint surface protective coating.
