  • 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

  • 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.

  • Acrylic functional urethane alkyd resin coating compositions
    Patent number: 4591518
    Abstract: An air oxidizable coating composition is disclosed comprising an ungelled urethane modified alkyd resin containing pendant polymerizable unsaturated groups attached to the alkyd through urethane linkages. The ungelled urethane modified alkyd is the reaction product of components comprising a hydroxyl containing, air oxidizable alkyd resin having an oil length of between about 20 percent and about 70 percent and an isocyanate-functional ethylenically unsaturated compound. Also disclosed are a process for coating the substrate with the coating composition and certain ungelled urethane modified alkyd resins.
