On the low rate of powder, spray a small area, high levels of heavy metals has been troubled powder coatings industry, Yu-feng powder Material Co., Ltd. for more than the needs of the Organization Department of Ministry of Chemical Industry and machinery after many years of joint research and development to produce powder coatings for packing High-calcium carbonate and calcium carbonate extinction so that the powder production sector colleagues, "the two high and one low" powder coating (that is high on the extraction rate, high-spraying area, low heavy metal content) wishes to come true, is of epoch-making significance.

         One advantage of
                 (1) non-heavy metal.
                 (2) reduce the proportion of powder coatings, powder on the increase rate of increase in spraying area.
                 (3) increase to cover rate.
                 (4) for barium sulfate, to reduce production costs.
