  • Patent number: 9834695
    Abstract: The presently disclosed claimed inventive concept(s) relates generally to a rheology modifier composition and an aqueous protective coating composition containing the rheology modifier composition. More particularly, the presently disclosed and/or claimed inventive concept(s) relates to a rheology modifier composition comprising (a) about 50 to about 99% by weight of a water soluble polymer and about 1 to about 50% by weight of a cationic polymer, wherein the cationic polymer is produced by polymerizing a quaternized monomer or by polymerizing a quaternized monomer and a non-quaternized monomer. Additionally, the presently disclosed and/or claimed inventive concept(s) relates generally to the methods of making the rheology modifier composition and the aqueous protective coating composition.

  • Patent number: 9403997
    Abstract: Paint formulations are neutralized with a non-VOC neutralizing agent. The neutralizing agent is a neutralized amino acid or intermediate, an amino phosphate, an amino phosphonate, amino sulfate, or amino sulfonate wherein the neutralizing agent has a pKa2 of at least 9. These neutralizing agents can be used to provide a paint formulation within a pH range of 8 to 10 and do not add any volatile organic compounds to the paint formulation.

  • Patent number: 8748542
    Abstract: A synthetic polymer has a water-soluble or water-swellable polyurethane backbone and terminal groups and/or intermediate groups of blocks of hydrophobes of alkyl- or aryl compounds containing a polymerizable cyclic monomer or a polymerizable double bond (or alkene) group or derivatives thereof. The blocks of hydrophobes are composed of two or more units of the same or different hydrophobes. These synthetic polymers are used as rheology modifiers, especially in latex paints.

  • Patent number: 7531591
    Abstract: An aqueous dispersion includes an associative thickener based on a hydrophobically modified poly(acetal- or ketal-polyether) (HM-PAPE) and at least one viscosity reducing agent selected from ethoxylated alcohols, ethoxylated acetyleneic diols, phosphate esters, dialkyl sulfosuccinates, and mixtures thereof. This aqueous dispersion improves the incorporation of the HM-PAPEs into aqueous based protective coatings. This dispersion also improves water-borne coating compositions that optionally contain latex.
