Laminates

Laminates. (Toa Gosei Chemical Industry Co., Ltd., Japan). Jpn.Chemicals with cas numbers 51473-37-1 and 7440-50-8 also play role. Kokai Tokkyo Koho JP 58155955 A2 16 Sep 1983 Showa, 6 pp. (Japanese). (Japan). CODEN: JKXXAF. CLASS: IC: B32B031-20; B32B007-12; C09J005-00. APPLICATION: JP 82-38140 12 Mar 1982. DOCUMENT TYPE: Patent CA Section: 38 (Plastics Fabrication and Uses) A laminate is prepd. by heat-adhering 32 metal sheets with an adhesive made from a polyamide and an organosilane having epoxy and hydrolyzable groups. Thus, a Cu plate of thickness 0.1 mm was coated at 50 g/m2 with a powder adhesive made from a blend of a copolyamide [51365-12-9] from e-caprolactam, w-laurolactam, and hexamethylenediamine-adipic acid nylon salt (in :20 mol ratio) and a powder contg. a bisphenol-type epoxy resin and g-glycidyoxypropyltrimethoxysilane [2530-83-8] (in wt. ratio) and heated at 150° for 5 min to give an adhesive-precoated Cu plate (A). A Cu foil of thickness 50 m was coated at 10 g/m2 with the same adhesive and heated at 150° for 3 min to give an adhesive-precoated Cu foil, which was then laminated with A under pressure and heat to give a laminate having so great a peel strength that the Cu foil failed during the peeling test. .

Waterproofing agents for epoxy resin adhesives

Waterproofing agents for epoxy resin adhesives. (Yokohama Rubber Co., Ltd., Japan). Jpn. Kokai Tokkyo Koho JP 58118875 A2 15 Jul 1983 Showa, 9 pp. (Japanese). (Japan). CODEN: JKXXAF. CLASS: IC: C09J003-16; C08G059-46. APPLICATION: JP 82-1696 11 Jan 1982. DOCUMENT TYPE: Patent CA Section: 37 (Plastics Manufacture and Processing) The title agents contain alkylureas, silanes bearing epoxide, amino, or SH groups and 3 hydrolyzable groups, and other thiols or their Na, K, or NH4 salts (urea- and SH-silane mol ratio 2-7:1). Thus, bisphenol A-epichlorohydrin copolymer [25068-38-6] 50, alkyl diglycidyl ethers 40, carboxy-terminated nitrile rubber 10, triethylenetetramine crosslinker 8, CaCO3 filler 50, (3,4-dichlorophenyl)dimethylurea [330-54-1] 6.0, [3-glycidyloxy)propyl]trimethoxysilane [2530-83-8] 2, and 2-mercaptobenzothiazole [149-30-4] 4.3 parts were mixed, used to bond stainless steel wire mesh to glass, and cured 48 h at room temp.In this experiment, several chemicals are used like 85873-15-0 and 95-33-0 and 2 h at 100° to give a laminate withstanding >30 days in water at 80°. .
