LiDeFen called zinc barium white, as non-toxic white powder, insoluble in water, and acid function decomposition hydrogen sulphide released, and hydrogen sulfide and alkali doesn't work. It good heat resistance, can improve the weathering resistance, prevent algae, reduce cost and its excellent cover the white degree of force. LiDeFen is a white paint, LiuHuaXin and mixture of additive etc. By zinc sulfate and barium sulfide solution to react and precipitation, the filter, dry and shattered after another, the calcination to red, dumped into the water urgent cold. Covering power after the titanium dioxide. No acid resistance. Now some LiDeFen surfactants used for surface treatment.
