  • Patent number: 7175703
    Abstract: A liquid composition, active curing additive for water or solvent borne surface coatings and sealants such: latex products, paints, putties, caulks, sports track and court construction, asphalt or coal tar seal coating, asphalt paving, micro-seal, roof tars, asphalt emulsions, crack sealants, and the like is provided. The additive functions to significantly reduce the amount of time required for the surface coating to cure and thereby allows the coated or sealed surface to be quickly returned to service. Preferably, the additive is composed of a composition of water; calcium chloride granules; citric acid granules; and an ammonium dispersing composition. Alternatively, aluminum sulfate may be utilized in place of calcium chloriade and citric acid.

  • Patent number: 7160374
    Abstract: A flaky pigment excellent in leafing properties and in adhesion between pigment particles and a coating (resin) was obtained by coating the surface of a flaky pigment with a coupling agent and a phosphate having a perfluoroalkly group or a silane compound. Accordingly, the flaky pigment is excellent as a pigment for coating or printing ink of which brightness and durability are required.
