Substrate using difference galvanized sheet and galvanized sheet: galvanized and aluminum zinc alloy layer compared to the chemical nature of the relatively active, and therefore a greater corrosion resistance difference. Tested under the same conditions, the outdoor show, galvanized plate for more than four times the service life of galvanized sheet. (2) differences in the surface paint surface paint material resin polyester resin (PE), polyester resin reinforced silicide (SMP) and polyvinylidene fluoride resin (PVDF). Conventional solvent coating system - polyester resin (PE): polyester resin topcoat (Regalar Polyester, referred to as PE) is a conventional paint system color coated paper, such as oleic acid resin is not affected fat color coated paper Which is good, in the relatively superior performance characteristics. The coating has a good flexibility, adhesion and processability. But PE paint and coating for resistance to sunlight chalking is not ideal, and therefore the use of PE coating still subject to certain restrictions, are generally used for air pollution is not serious, or severe environmental pollution in industrial areas, its life relatively lower. General life of eight to ten years. Currently on the market to use more color-coated, including Bao board, Wuhan Steel and most of Taiwan, South Korea imported plate, belonged PE coating. Best solvent coating system - polyvinylidene fluoride resin (PVDF): polyvinylidene fluoride resin coating system (Poly-vinylidene Fluoride, referred to PVDF or PVF2), is the world's most outstanding solvent coating systems System also the construction industry with the most advanced color-coated paint products. Because there is a strong bonding force between the bond and the bond PVDF, therefore coatings having a very good color retention and corrosion resistance, weather resistance (gloss retention, chalk resistance, color durability) also all coating systems The most outstanding. Buying large molecular weight PVDF color coated paper, and is a direct bond structure painted volume prices, so in addition to excellent chemical resistance, the mechanical properties, resistance to UV and heat resistance are also very excellent. Polyvinylidene difluoride resin coating system in the American system, known as Kynar 500; in Australia system, is applied in XSE system. Polyvinylidene fluoride resin coating systems under conventional outdoor climate and adequate rainfall washing circumstances, in thirty to thirty-five years, the paint does not produce cracks, flaking or loose.
