Patent number: 4035436Abstract: A nylon-base adhesive composition for metals is composed of 100 parts by weight of a mixture of nylon 11 and nylon 12 and about 2-40 parts by weight of nylon 6-12. The adhesive composition has excellent heat resistance and water resistance and is particularly useful for making cans. The properties of the adhesive composition can be further improved by adding thereto polyethylene, an ionomer, or a mixture thereof.A process for bonding steel sheets using the adhesive is also disclosed.Type: GrantFiled: November 12, 1975Date of Patent: July 12, 1977Assignee: Toagosei Chemical Industry Co., Ltd.Inventors: Takashi Matsubara, Yoshihito Uramoto, Daizo Matsuoka

Patent number: 4035214Abstract: Process for transferring overlayed multiple ink patterns from the surface of a release blanket to a receiving surface on a container or other formed article being printed. A substantially transparent film is first formed on the release blanket, with each ink pattern being printed sequentially over this release film. Proper printing on the release film without picking the release film or previously applied ink films is obtained when certain adhesive and cohesive relationships are maintained between the ink films and the release film. An adhesive film may be formed on the article to be printed, or it may be formed over the ink films and the release film on the release blanket. The receiving surface on the article to be printed is brought into contact with the films on the release blanket, with a resulting total transfer of the films on the blanket to the surface of the article.Type: GrantFiled: July 21, 1975Date of Patent: July 12, 1977Assignee: American Can CompanyInventors: Laurence Verlan Shuppert, William Duane Hanson, Robert Alfred Willer

Patent number: 4034132Abstract: The adhesion of propylene polymer layers to enamel coated metal surfaces is improved by incorporating an adhesion promoting amount of a carboxyl modified polypropylene resin in the enamel.Type: GrantFiled: September 25, 1975Date of Patent: July 5, 1977Assignee: The Continental Group, Inc.Inventor: Ernesto H. Manuel

Patent number: 4022649Abstract: A metal laminate having high thermal stability is produced by forming a cured film layer of a thermally stable heterocyclic polymer such as polyamide imide having only a small volatile content on at least one surface of one or both of metal plates or foils such as aluminum, separately forming an adhesive layer of a thermally stable heterocyclic polymer having a thickness of one-third or less of the above film layer and containing a volatile matter in an amount of not more than 20% by weight, and then heat bonding both of the metal plates or foils through the above adhesive layer with the film layer being allowed to face the adhesive layer. The metal plates and foils are mutually insulated.Type: GrantFiled: April 7, 1975Date of Patent: May 10, 1977Assignee: Nitto Electric Industrial Co., Ltd.Inventors: Keisuke Nakagome, Toshiharu Suzuki

Patent number: 4012270Abstract: Propylene polymers are heat sealed to enamel coated metal surfaces, the enamel having incorporated therein an adhesion promoting carboxyl modified polypropylene resin. The bond strength of the heat seal is improved by incorporating the carboxyl modified polypropylene resin in the enamel coating formulation dissolved in a hot (heated above 100.degree. C) organic solvent solution selected from aliphatic acids, alcohols and hydrocarbons having at least 10 carbon atoms.Type: GrantFiled: September 25, 1975Date of Patent: March 15, 1977Assignee: The Continental Group Inc.Inventor: Chester W. Fitko

Patent number: 4004061Abstract: Making film adhesives from a thermosettable resin composition presents difficulties if the composition is not soluble in a volatile solvent, or not readily fusible without gelling prematurely, or undergoes undesirable advancement on being subjected to extrusion procedures.Such compositions in the form of solid particles can be made into film adhesives by coating a carrier with a readily-curable thermosettable resin composition, which is preferably tacky, applying the solid particles to the coating, and then curing the coating under conditions such that the particles of thermosettable resin composition remain curable.Type: GrantFiled: January 14, 1974Date of Patent: January 18, 1977Assignee: Ciba-Geigy CorporationInventors: Gordon Robert Creighton, Barry James Hayes
