  • Polyester formulations for hot-melt wood adhesives
    Patent number: 4975477
    Abstract: Disclosed are certain polyester adhesive blend compositions comprising about 45-90 wt. percent of a copolyester, about 3-15 wt. percent of a plasticizer, and about 7-40 wt. percent of a tackifying resin. The blends are particularly useful in hot-melt glue gun applications.
    Type: Grant
    Filed: April 7, 1989
    Date of Patent: December 4, 1990
    Assignee: Eastman Kodak Company
    Inventors: Abraham J. Cox, Max F. Meyer, Jr.
  • Copolyesters and formulations thereof for adhesives
    Patent number: 4966959
    Abstract: Disclosed are certain copolyesters comprising an acid component of (1) 60 to 75 mol % of terephthalic acid, and (2) 25 to 40 mol % of a dicarboxylic acid, and a glycol component of (1) 55 to 65 mol % 1,4-butanediol, and (2) 35 to 45 mol % one or more other aliphatic diols. The copolyester or formulation thereof with a tackifying resin has excellent properties for use as a glue gun adhesive.
