  • Patent number: 8841360
    Abstract: The present invention relates to a coatings composition comprising an alkyd, a pigment, a rheology modifier, a radical producing oxidoreductase, and one or more additives, wherein the alkyd contains at least one C6-30—C(O)O— group having at least one diallylic group. The coatings composition of the present invention cures relatively rapidly without ancillary crosslinking agents and with minimal, if any, VOCs from solvents or coalescents.

  • Publication number: 20070100074
    Abstract: According to the present invention, aqueous multi-stage polymer dispersions comprising an acid-functional first polymer and an epoxy-functional second polymer, wherein 90 mole % or more of the said epoxy groups, based on the moles of epoxy groups in the monomer mixture used to form the second polymer, are retained in the aqueous dispersion after said dispersion is stored in a sealed container for 10 days at 60° C. Further, methods of making the aqueous multistage polymer dispersion comprise polymerizing the monomers used to make the second polymer in the presence of an aqueous dispersion of the first polymer. Preferably, the second polymer is formed in the presence of 0.3 wt. % or less, based on the total weight of the first polymer and the ingredients to form the second polymer, of one or more strong acid surfactant, and 3) 0.1 wt.

  • Publication number: 20060217453
    Abstract: A formulation for repelling particulate matter on the surface of a coating comprising polymeric nanoparticles having a mean particle diameter of from 1 to 50 nm. The polymeric nanoparticles may further be functionalized to impart additional characteristics to modify the surface of the dried coating to minimize the chances for particles to become embedded or attached to the coating.

  • Publication number: 20050014883
    Abstract: The present invention relates to a process for preparing an aqueous polymer dispersion containing polymer particles dispersed in an aqueous medium. The process includes providing first polymer particles; adding a hydrophobic polymerization blocker or a styrenic monomer polymerization blocker to the aqueous medium containing the first polymer particles; and preparing second polymer particles in the presence of the first polymer particles. The aqueous polymer dispersion contain first polymer particles and the second polymer that differ according to at least one attribute such as particle diameter, molecular weight, composition, glass transition temperature, or morphology; or contain polymer particles having a broad polydispersity. The aqueous polymer dispersion prepared by the process of this invention is useful in a wide range of applications, including paints, adhesive, binders for nonwovens, and binders for paper coatings.
