| abstract | 1424282 Coated glass containers DART INDUSTRIES INC 6 March 1973 [7 March 1972] 10711/73 Heading B2E [Also in Division B6] Coated glassware comprises: a glass container; optionally a lubricious base coating; and a coating extending substantially completely over the exterior surface of the container, said coating being formed of a solid, resilient, locally distortable thermoplastic material partially adhered to said container or to said base coating, if present, and being under tension. The coating is preferably 0.006 to 0.030 inches thick with the glass 0.006 to 0.150 inches thick. The partially adhered coating preferably comprises at least 60 wt % polyethylene base resin blended with at least one acidic polymer material from the group consisting of oxidised polyolefins, oxidised waxes and polymers comprising an unsaturated carboxylic acid or anhydride, such that the acid number of the blend is at least 0.5 and preferably less than 20. Examples of unsaturated acid monomers are acrylic, methacrylic, ethacrylic, cationic, fumaric, maleic, itaconic, vinyl sulphonic acids, maleic anhydride, monomethyl or monoethyl maleate or fumarate. The acidic polymer may be a homopolymer of the above mentioned monomers or a copolymer with α-olefins such as ethylene, propylene or but-1-ene 3 methyl but-1-ene or 4-methyl pent-1-ene, or vinyl monomers such as styrene, vinyl acetate or esters of acrylic or methacrylic acids. Several specific examples of copolymers are given. The acidic polymer may be a terpolymer of one of the above acidic monomers, one of the above olefins, and a vinyl compound such as vinyl acetate, vinyl chloride, vinyl alcohol, vinyl ethers or vinyl fluoride. The polyethylene resin may be homopolymer or copolymer which provides additional short chain branches such as: α-olefins other than ethylene such as propylene, but-1-ene, 3, methyl but-1-ene, 4, methyl pent-1- ene; vinyl compounds such as styrene, vinyl esters, vinyl ethers, vinyl fluoride, vinyl chloride, vinyl alcohol; vinylidene compounds such as the fluoride and chloride, esters such as ethyl or vinyl esters of acrylic acid, methacrylic acid, crotonic acid, itaconic acid, maleic acid or fumaric acid; acrylonitrile, fumaronitrile; acrylamides; or carbon monoxide. The blend can be formed before application by coating particles of the polyethylene resin with the acidic polymer, by mixing particles of polyethylene and acidic polymer or by melt blending. The method of application may be emulsion, spray, electrostatic or fluidised bed. The container may be precoated with a layer of tin oxide or titanium dioxide and a second coating selected from the group polyethylene, polyoxyethylene monostearate, morpholino stearate, triethanolamine stearate, or mixtures thereof. |
