RELATIONSHIP BETWEEN POROSITY AND DIFFERENT SHAPES OF PIGMENT
Different kinds of pigments, kaolin, ground calciuM carbonates (GCC-HC60) and precipitated calciuM carbonate (PCC-A40), with different amount of coating colours and latex, were used to find out the relationship between porosity and different shapes of the pigments. The solid content and the drying tempetature were also discussed to see the effects of these two parameters. High drying temperature always leads to high porosity for all the coating colors while low amount of latex (4pph) leads to low porosity for the film coated with PCC-A 40.At a high amount of latex (12pph), HC 60 works well with latex 319, while kaolin performs better with latex 300.As for the thin coating layers, HC 60 can generatethe best porosity.
