  • Acrylic emulsion polymers for removable pressure sensitive adhesive applications
    Patent number: 8580875
    Abstract: An improved aqueous acrylic emulsion pressure sensitive adhesive (PSA) composition of improved sheer strength includes an aqueous acrylic emulsion including at least one hydrophobic monomer, at least one hydrophilic monomer, and at least one hydrogen bonding monomer; and a peel control additive. The PSA composition is substantially devoid of phosphate-based surfactants.
    Type: Grant
    Filed: December 12, 2007
    Date of Patent: November 12, 2013
    Assignee: Ashland Licensing and Intellectual Property LLC
    Inventors: Kang I. Lee, Keith D. King
  • Acrylic emulsion pressure sensitive adhesive composition
    Patent number: 8252425
    Abstract: An improved aqueous acrylic emulsion pressure sensitive adhesive composition of diminished foaming and being formulated from an aqueous acrylic emulsion including at least one carboxyl monomer having a residual carboxyl group, which residual carboxyl group is neutralized with a hydroxyl-functional amine, such as a trialkanolamine.
