  • Patent number: 6124401
    Abstract: This invention provides for a coating composition comprising: (A) at least one polymeric material selected from (i) at least one homopolymer of ethylene having a melt index of at least about 220 grams per ten minutes as determined by ASTM D1238, condition 190/2.16, or (ii) at least one copolymer of ethylene and a second ethylenically unsaturated monomer having a melt index of at least about 20 grams per ten minutes as determined by ASTM D1238, condition 190/2.16, or (iii) at least one thermoplastic acrylic homopolymer or copolymer having a glass transition temperature (Tg) of greater than 0.degree. C. but less than 110.degree. C., or (iv) a mixture of (i), (ii) and/or (iii); and (B) at least one thermoplastic polymeric material different than (A) having a melting point in the range of about 80.degree. C. to about 130.degree. C.
    Type: Grant

  • Patent number: 5286270
    Abstract: The present invention provides a method of producing an enamel finish on formed section of glass. The enamel composition partially crystallizes upon heating, thereby helping to prevent the forming and handling equipment from sticking and/or adhering to the composition during the forming operation. The enamel composition includes a crystallizable glass frit portion and a seed powder. The crystallized glass frit portion includes precursors from which Zn.sub.2 SiO.sub.4 can be crystallized upon firing of the enamel composition. The seed powder causes at least a portion of the precursors to crystallize upon firing such that during firing at least a part of the crystallizable glass frit yields crystallized Zn.sub.2 SiO.sub.4 formed by the precursors. Preferably, the precursors comprise ZnO and SiO.sub.2, and the seed powder comprises crystalline Zn.sub.2 SiO.sub.4. The enamel composition also preferably includes bismuth oxide (Bi.sub.2 O.sub.

  • Patent number: 5208191
    Abstract: The present invention provides a new and useful enamel composition and method of using the same for producing an enamel finish on a formed section of glass. The enamel composition partially crystallizes upon heating, thereby helping to prevent the forming and handling equipment from sticking and/or adhering to the composition during the forming operation. The enamel composition includes a crystallizable glass frit portion and a seed powder. The crystallized glass frit portion includes precursors from which Zn.sub.2 SiO.sub.4 can be crystallized upon firing of the enamel composition. The seed powder causes at least a portion of the precursors to crystallize upon firing such that during firing at least a part of the crystallizable glass frit yields crystallized Zn.sub.2 SiO.sub.4. The enamel composition also preferably includes bismuth oxide (Bi.sub.2 O.sub.3) in order to help further ensure that no sticking and/or adhering problems develop during the forming operation.

C. to about 130.degree. C. and being miscible with (A). The invention further provides for a process for applying the foregoing coating composition to a substrate such as glass, ceramic, metal, fiberboard, textile or plastic substrate (e.g.
