Low on powder, spray a small area, heavy metal content has been plagued by the problem of higher powder coatings industry, Materials Ltd. Yufeng powder required for the above, the Organization Department of Ministry of Chemical Industry and machinery after many years of joint research and development, to produce special filler powder coating high light calcium carbonate and calcium carbonate extinction, so that powder production sector colleagues "two high and one low" powder coating (that is, on pink high rate, high spray area, low heavy metal content) of the desire to become a reality, it is of epoch-making significance.

一、quality indicators
