  • HYDROPHOBIC COATINGS
    Publication number: 20110021698
    Abstract: The present disclosure provides embodiments of polymeric particles, aqueous coating compositions, coating compositions, processes of making polymeric particles hydrophobic coatings, processes for making hydrophobic synthetic latex compositions, processes of forming polymeric particle agglomerates for use in a hydrophobic coating, and process of making hydrophobic polymeric binders. In some embodiments, the polymeric particle includes a polymer having an elastic modulus greater than about 108 Pascal (Pa), measured at 25 degrees Celsius (° C.) and at a deformation frequency of 1 radian per second, where the polymeric particle is hydrophobic, and where the hydrophobicity is achieved by polymerizing a monomer in a mixture comprising water and a fatty acid, or salt thereof, where the monomer contains less than about 3 parts acid monomer per 100 parts dry monomer.

  • Process for making coated paper or paperboard
    Patent number: 7473333
    Abstract: The present invention refers to a method of producing a coated paper or paperboard, but excluding photographic papers, comprising the steps of: (a) forming a free flowing curtain comprising at least one layer, whereby the composition forming at least one layer of the free flowing curtain has a high shear viscosity of at least about 50 mPa·s, and (b) contacting the curtain with a continuous web substrate of basepaper and paperboard.

  • Hydrophobic coatings
    Publication number: 20080245273
    Abstract: A process for improving the hydrophobicity of architectural coating compositions and adhesive release surface compositions, the process comprising preparing at least one of said compositions using the following components: inorganic particles, at least one fatty acid or a salt thereof, a polymeric binder, and water. There is further disclosed a method for preparing an aqueous composition and a method of coating a substrate.
