Wet Mica Powder
1.Our Wet Mica Powder use good quality mica materials,manufacturing process with washing,refining,dipping,grinding and crashing,cold-drying,screening,finally get a good quality filler.
2.It is unique manufacturing technique retains the mica flakes structure,redius-thickness ration,higher index of refraction,high purity,higher whiteness,higher luster,lower sand and iron content,etc.
3.The above performances highly improve mica’s applications in resin and plastics,paint and coating,rubber,lubricant.etc.
