Coated calcium carbonate
To produce this coated filler, a solution of stearic acid is sprayed onto dry calcium carbonate. Then it is milled to get an even coating of the particles. The result is a beautiful, hydrophobic white filler ready for use in all sorts of plastic applications. Be careful when you handle it though. It sticks like crazy to anything organic ...
Kaolin in paper filling and coating
The thickest particles, calcined kaolin, nearly eliminate the number of missing dots. Other blocky particles such as wet-ground calcium carbonate do not give a reduction in the number of missing dots. This discrepancy is probably related to poor coating holdout imparted by the broad particle size distribution of wet-ground calcium carbonate.
