Compositions of large particle calcined kaolin clay and methods of making the same

摘要

The present invention provides compositions, and method for making same, comprising large particle size, calcined kaolin clays that, when used in paint formulations, provide paints having low sheen and good weathering resistance. Compositions of the invention include a composition comprising the pigment produced by a process comprising calcining a feed comprising kaolin having a median equivalent spherical diameter (e.s.d.) as measured on a Sedigraph 5100 of greater than about 2.0 microns and having
