  • Patent number: 7459496
    Abstract: This invention relates to waterbone coating compositions having improved compatability with metal pigments, i.e., improved shelf life and reduced gassing and gellation. The composition comprise at least one aqueous dispersion of (1) at least one emulsion copolymer polymerized from (a) at least one ethylenically unsaturated anionic monomer and (b) at least one other olefinically unsaturated monomer, said copolymer being made using at least one phosphate surfactant having at least one phosphorus acid group or salt thereof, said copolymer being crosslinked, and (2) at least one non-water soluble metal pigment. The compositions are useful in paints and other coatings.

  • Patent number: 6017997
    Abstract: A waterborne dispersion of a polyurethane polymer is disclosed, which is useful as a film having improved mechanical properties. More particularly, the film has properties comparable to rubber; including, a percentage elongation greater than 700%; a tensile strength greater than 3500 psi; a 100% modulus below 450 psi; a 300% modulus below 700 psi; and, a 500% modulus below 1500 psi. The film can be prepared in the absence of a solvent, thus making it attractive for a variety of protection products for medical and industrial applications such as gloves, condoms, catheters, and the like. The polymer is useful as a coating for textiles, such as backcoatings, fabric or fiber saturants, finishes, or transfer coatings, or other textile and non-textile applications where good elastomeric properties would be useful.
