The first commercial synthetic opacifier was introduced to the market in the early 1980s. Today, Hollow Sphere synthetic Pigments (HSPs) have become standard, common, value-added ingredients in both the paper and architectural coatings markets, with worldwide acceptance.1
In both markets, Rohm and Haas has developed a family of hollow-sphere polymers that provide maximum hiding at minimum cost without sacrificing the other performances of the formulations. The use of HSP, which provides value to paints and paper coatings, could be extended to a number of industrial applications such as metal coatings, traffic paints and graphic arts.
