Abstract
Abstract Disclosed herein is a latex coating composition containing from 10 to 30% by weight of a porous particulate material such as perlite and from 2 to 4% by weight of a stabilizer blend comprising from 20 to 65% by weight of said blend of a biosynthetic polysaccharide, from 35 to 80% by weight of said blend of a finely divided inorganic filler and from 0 to 35% by weight of a cellulosic agent. The coating composition exhibits excellent insulating properties and does not shrink during storage. The method of preparing the paint composition is also disclosed.
