Caitu natural exposure test, a) the use of color-coated silver color coated in an industrial environment, should give full consideration to the industrial fallout factors embedded in the coating. The results showed that, polyvinylidene fluoride products with the best performance in an industrial environment. The density and improved chemical stability of the coating color coated product is critical in industrial environments to improve service life. 2) When using color-coated in a marine environment, should be fully taken into account the impact of salt spray atmosphere. The results showed that, polyvinylidene fluoride products with the best performance in the marine environment. 3) selection of color-coated products, should take into account the color of color-coated for durability impact caitu, organic pigments are generally more durable products, poor color-coated inorganic pigment product specifications, and silver pigments must considering its ability to acid and alkali. 4) Buy caitu Generally, the color coating has a better ability to acid rain atmosphere, a harsh environment is desirable materials. 5) in China, Hainan test point is the best one can examine the location of color-coated durability, it also has the strongest ultraviolet radiation and corrosive atmosphere harsh ocean, different colors can be objectively evaluated in a short period of time , color-coated varieties resistance to environmental aging ability.
