BOST-MP01 is a tiny ball of insulating material with moderate hardness, which is sprayed on the surface of the coated glass to prevent scratches between the coated glass. The material does not cause any corrosion to the film of the coated glass and the gap between the glass after lamination is similar to the thickness of the paper, but the cost is about 1/6 of the paper, and products could be removed with a soft brush and is also easily washed off by water. lt has been widely used in coated glass sheets.
