Composition and process for the treatment of clay slimes. Raba, Carl F., Jr.; Smith, Robert L.; Huang, Francis Y. (Monier Resources, Inc., USA). U.S.There are some reagents like 9003-05-8 is used in this study. US 4478736 A 23 Oct 1984, 7 pp. (English). (United States of America). CODEN: USXXAM. CLASS: IC: C02F001-52; C02F001-56; C02F011-14. NCL: 252180000. APPLICATION: US 83-457930 14 Jan 1983. DOCUMENT TYPE: Patent CA Section: 60 (Waste Treatment and Disposal) Section cross-reference(s): 49, 54 Clay-contg. slimes (e.g., from phosphate rock beneficiation) are dewatered by treatment with a flocculating agent prepd. from hydrated fly ash, a silane coupling agent, and polyacrylamide (I) [9003-05-8]. For example, when a phosphate slime was treated with an agent prepd. from hydrated fly ash, triacetoxyvinylsilane [4130-08-9], and I, sedimentation was accomplished without the aid of mech. means. .

Ambient temperature, moisture-curable acrylic-silane coating compositions having improved potlife

Ambient temperature, moisture-curable acrylic-silane coating compositions having improved potlife. Chang, Wen-Hsuan; Hartman, Marvis E.; Scriven, Roger L. (PPG Industries, Inc., USA). U.S. US 4043953 23 Aug 1977, 6 pp. (English). (United States of America). CODEN: USXXAM. CLASS: IC: C08L091-00. NCL: 260185000. APPLICATION: US 75-574194 2 May 1975. DOCUMENT TYPE: Patent CA Section: 42 (Coatings, Inks, and Related Products) The potlife of an ambient temp., moisture-curable coating compn. comprising an acrylic-silane interpolymer and a cure-accelerating catalyst is increased by addn. of 0.5-15% (based on wt. of interpolymer) RnSi (OR1)4-n [R = vinyl or Ph, R1 = Me, Ac, or EtO (CH2)2, n = 0 or 1). Thus, a coating compn. contg. ::900 (wt. ratio) acylonitrile-butyl methacrylate-2-ethylhexyl acrylate-.gamma.-methacrylolyoxypropyltrimethoxysilane-methyl methacrylate copolymer [64433-11-0] 200.0, Bu2Sn dilaurate catalyst 1.0, and vinyltriacetoxysilane (I) [4130-08-9] 5.0 parts formed a gel skin on the surface after 30 and 6 days at room temp. and 120.degree.F, resp., compared with .ltoreq.16 and .apprx.2 h, resp., for a similar compn. not contg.
