Patent number: 5859154Abstract: An adherent coating composition and method has a resin composition that is the polymerization reaction product of one or more polyhydric alcohols and two polybasic carboxylic acids and salt forming compounds of phosphorus. The carboxylic acid is comprised of at least adipic acid and phthalic anhydride in a mole ratio in the range of about 0.6:1 to about 3:1, and the phosphorus compound is present in the range of about 1 to about 5 weight percent of the resin composition. The resin composition can have a weight average molecular weight in the range of about 1100 to about 4000 and an acid value in the range of about 5 to about 40. Optionally, the resin can have up to about 35 weight percent of tetrahydrophthlic anhydride. The resin composition is ungelled and curable with crosslinking agents in an amount of about 30 to about 90 weight percent of resin to about 10 to about 45 weight percent of the crosslinking agent.Type: GrantFiled: September 26, 1997Date of Patent: January 12, 1999Assignee: PPG Industries, Inc.Inventors: Rodger G.

Patent number: 5684083Abstract: A composition is disclosed which includes a urethane resin containing reactive ethylenically unsaturated groups and hydroxyl groups, which is preferably derived by reacting a polyisocyanate and an isocyanate reactive group-containing unsaturated monomer selected from the group consisting of hydroxyalkyl acrylates, hydroxyalkyl methacrylates, hydroxyalkyl acrylamides, hydroxy functional allylic compounds, and mixtures thereof to form an isocyanate group-containing reaction product which is then reacted with an organic polyol wherein the equivalent number of hydroxyl groups is in excess compared with the equivalent number of isocyanate groups. The composition also includes an aminoplast resin for reaction with hydroxyl groups on the urethane resin in an amount of less than about 10% by weight based on solids of the composition which is effective in thin film curing of the composition.Type: GrantFiled: May 22, 1995Date of Patent: November 4, 1997Assignee: PPG Industries, Inc.Inventors: Rodger G.

Patent number: 4196107Abstract: This invention relates to coating compositions which are "solid" prior to application, yet, which when applied to a substrate, flow and level in a manner similar to conventional coating compositions. The coating compositions of the invention comprise a gelled coating composition, capable of application and flow on a solid substrate comprising: (a) a water reducible polymer, (b) water, (c) an electrolyte, and (d) a colloidal gelling agent, gelable by interaction with the electrolyte, in an amount sufficient, when interacted with said electrolyte, to gel the composition to form a stable semisolid and to provide a composition reducible to a coating application viscosity upon the application of a relatively small shearing force at a relatively small shearing rate; which gelled coating composition, after being sheared to a coating application viscosity, does not recover substantial colloidal gelling agent contributed gel structure.Type: GrantFiled: June 5, 1978Date of Patent: April 1, 1980Assignee: PPG Industries, Inc.Inventors: James E.

Patent number: 4089800Abstract: Void-containing microcapsules are prepared by a method featuring gellation of an organic polymer with the simultaneous precipitation of an organic liquid non-solvent. The method involves the preparation of a solution containing an organic polymer, a good solvent for the polymer and an organic liquid non-solvent which is miscible with the polymer solvent. The solution is then atomized into a bath containing a liquid which is miscible with the good polymer solvent but which is immiscible with the organic liquid non-solvent. The bath liquid extracts out the good polymer solvent, causing gellation of polymer around discrete droplets of the organic liquid non-solvent, which simultaneously precipitates out of the solution as the good polymer solvent is extracted, thereby producing microcapsules having encapsulated therein the non-solvent. The organic liquid non-solvent can then be removed as by evaporation to provide void-containing microcapsules.Type: GrantFiled: April 4, 1975Date of Patent: May 16, 1978Assignee: PPG Industries, Inc.Inventor: Rodger G.

Patent number: 4064294Abstract: Microcapsules are produced in-situ in a film or during the manufacturing process of a water-based coating composition from which the film is formed. A principal process involves the in-situ production of void-containing microcapsules in a film formed from a water-based coating. This principal process involves as a first step the preparation of a polymer composition which may be a homogeneous solution containing a water-immiscible organic polymer, a water-immiscible solvent for the polymer, and a water-immiscible lower volatility non-solvent which is miscible with the solvent; or an emulsion containing as the continuous phase a water-immiscible organic polymer dissolved in a water-immiscible solvent for the polymer and, as the discontinuous phase, droplets of a lower volatility non-solvent dispersed in the continuous phase. This polymer composition is then emulsified under agitation and in the presence of a surfactant into a water-based coating composition.Type: GrantFiled: June 2, 1975Date of Patent: December 20, 1977Assignee: PPG Industries, Inc.Inventors: Simon Babil, James A. Claar, Rodger G. Temple

Patent number: 3943080Abstract: Solid organic inert flatting agents are prepared by reacting urea or phenol and formaldehyde in a basic aqueous medium to provide a prepolymer solution, then blending the prepolymer in the presence of a protective colloid-forming material, subsequently acidifying the basic prepolymer solution so that particles are formed and precipitated in the presence of a colloid-forming material, as spheroidal beads, and finally collecting and, if desired, drying the urea or phenol formaldehyde particulate beads. These beads have a high flatting efficiency and may be incorporated in resinous vehicles to provide compositions that produce low glass coatings of desirable properties.Type: GrantFiled: August 1, 1974Date of Patent: March 9, 1976Assignee: PPG Industries, Inc.Inventors: Marco Wismer, Karl F. Schimmel, Rodger G. Temple
