Siloxane waterproofing impregnating coatings for inorganic materials

Siloxane waterproofing impregnating coatings for inorganic materials. Yoshioka, Hiroshi; Ono, Ichiro (Shin-Etsu Chemical Co., Ltd., Japan). Eur. Pat. Appl. EP 469624 A1 5 Feb 1992, 12 pp. DESIGNATED STATES: R: DE, FR, GB. (European Patent Organization). CODEN: EPXXDW. CLASS: ICM: C04B041-64. ICS: C09D183-04; C08K005-54. APPLICATION: EP 91-113031 2 Aug 1991. PRIORITY: JP 90-205383 2 Aug 1990. DOCUMENT TYPE: Patent CA Section: 42 (Coatings, Inks, and Related Products) Section cross-reference(s): 5, 58 Compns. that give durable, penetrating coatings with good fungicidal and mildewcidal properties for inorg. materials contain an organosiloxane with the general formula R1aSi(OR2)b(OH)cO(4-a-b-c)/2 (R1 = C1-18 hydrocarbyl; R2 = C1-4 hydrocarbyl; a = 0.1-1.5, b = 1-3, c = 0-1, a + b + c = 1.1-4) and R3R4dSi(OR5)3-d (R3 = org. group including a quaternary ammonium halide group; R4, R5 = C1-4 hydrocarbyl; d = 0, 1, 2) in (80-99.9):(0.1-20) wt. ratio. Thus, a JIS mortar sample was brushed with 300 g iso-PrOH contg. 98 g n-C10H21Si(OMe)3 and 2 g [C18H37NMe2C3H6Si(OMe)3]+Cl- (I) at 100 g/m2 and cured 7 days at 50% relative humidity to give a sample with water absorption 2.4% and coating penetration 3 mm. A JIS clay tile brushed with the same compn. and cured in the same way exhibited better resistance to 5 molds than a tile coated with a similar compn. not contg. I and a concrete block brushed with the same compn. 5575-48-4 and 27668-52-6 are just another two chemicals used in this study. and cured in the same way exhibited better resistance to staining after 12 mo outdoors than a block coated with a similar compn. not contg. I. .

Polyurethane compositions with good resistance to chlorine-containing water

Polyurethane compositions with good resistance to chlorine-containing water. Yoshizato, Akihiko (Asahi Chemical Industry Co., Ltd., Japan). Jpn. Kokai Tokkyo Koho JP 03292364 A2 24 Dec 1991 Heisei, 9 pp. (Japan). CODEN: JKXXAF. CLASS: ICM: C08L075-04. ICS: C08K009-04.Some commonly used reagents like 5575-48-4 and 4420-74-0 are used in this experiment. APPLICATION: JP 90-92986 10 Apr 1990. DOCUMENT TYPE: Patent CA Section: 40 (Textiles and Fibers) The title compns. for elastic fibers, etc., contain 0.1-10% (based on polyurethane) higher fatty acid- and/or silane coupling agent-treated hydrotalcites with av. size ￡1 mm. Thus, polymn. of 133.3 parts poly(tetramethylene glycol) and 31.2 parts MDI at 95° for 90 min and treating the resulting prepolymer with 2.34 parts ethylenediamine and 0.37 part Et2NH gave a polyurethane soln., which was mixed with TiO2 4, 4,4'-butylidenebis(3-methyl-6-tert-butylphenol) 2, 2-(2-hydroxy-3-tert-butyl-5-methylphenyl)-5-chlorobenzotriazole 0.7, and octadecanoic acid-finished Mg4.5Al2(OH)13CO3.3.5H2O (av. size 0.5 mm) 1%. The soln. was melt spun, dyed, and finished with tannin to give fibers showing strength halving time 68 h when immersed in 3 ppm NaClO, vs. 29 h for a control using nontreated hydrotalcite. .
