  • Ultraviolet light curable compositions based on iminated unsaturated polyesters for application to porous substrates
    Patent number: 4788108
    Abstract: Disclosed is a curable filler composition which resists absorption into a porous substrate, particularly one derived from wood, comprising: (1) a liquid, ungelled binder of an unsaturated polyester resin having number average molecular weight of from 500 to 3,000 derived from an ethylenically unsaturated carboxylic acid or anhydride thereof, the unsaturated polyester resin having been iminated with an alkylenimine, (2) one or more ethylenically unsaturated compounds different from and cocurable with the unsaturated polyester resin, (3) pigment, (4) a free radical initiator, and (5) optionally a carrier solvent for the filler composition.Disclosed is a method of minimizing absorption of a filler composition into a warm or hot porous substrate.Also disclosed is a porous substrate, particularly one derived from wood, having adhered to a substrate thereof the cured filler composition.
    Type: Grant
    Filed: June 15, 1987
    Date of Patent: November 29, 1988
    Assignee: PPG Industries, Inc.
    Inventors: John B. Saunders, Jr., Robert M. Piccirilli, William J. Schillinger, Ken W. Niederst
  • Ultraviolet light curable compositions for application to porous substrates based on unsaturated polyesters reacted with amino alcohols
    Patent number: 4775597
    Abstract: Disclosed is a curable filler composition which resists absorption into a porous substrate, particularly one derived from wood, comprising: (1) a liquid, ungelled binder of an unsaturated polyester resin having number average molecular weight of from 500 to 3,000 derived from an ethylenically unsaturated carboxylic acid or anhydride thereof, the unsaturated polyester resin having been reacted with a hydroxyl-containing amine selected from the group consisting of an alkanol amine having a secondary amino group, an alkanol amine having a primary amino group and a mixture thereof, (2) one or more ethylenically unsaturated compounds different from and cocurable with the unsaturated polyester resin, (3) pigment, (4) a free radical initiator, and (5) optionally a carrier solvent for the filler composition.Disclosed is a method of minimizing absorption of a filler composition into a warm or hot porous substrate.

  • Coating compositions containing organosilane-polyol
    Patent number: 4413086
    Abstract: Described are water reducible coating compositions comprising (A) an organosilane-polyol which is the reaction product of a hydrophilic polycarbinol and an organosilicon material selected from the group consisting of an organosilane, a hydrolyzed and condensed organosilane and mixture, thereof; and (B) a curing agent for the coating compositions.
