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 wishes to come true, is of epoch-making significance.
(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.
