(United States of America). CODEN: USXXAM.Several reagents with their cas registry numbers 26061-99-4 and 7429-90-5 are used here. CLASS: IC: C08K003-36; C08K003-08. NCL: 524158000. APPLICATION: US 82-430842 30 Sep 1982. DOCUMENT TYPE: Patent CA Section: 42 (Coatings, Inks, and Related Products) A rheol.-control agent extending shelf life and reducing sagging of high-solids coatings comprises a blend of colloidal silica, polymeric bridging agent, arom. sulfonic acid curing catalyst, and PrNH2 [107-10-8]. The agent provides metallic automotive finishes with high gloss and image distinctness and no wrinkling. Thus, paint was formulated contg. acrylic acid-Bu acrylate-hydroxyethyl acrylate-Me methacrylate-styrene copolymer [26061-99-4], coarse Al flakes, and an agent consisting of fumed silica (surface area 200 m2/g, av. diam. 120 mm), nonionic polyfluorocarbonpolyoxyethylene bridging agent (10-20% F, mol. wt. ~20,000), dodecylbenzenesulfonic acid [27176-87-0], and PrNH2. .

Dyeing of wool at low temperatures

Dyeing of wool at low temperatures. Bendak, A.; Abdou, L. A. (Text. Res. Div., Natl. Res. Cent., Cairo, Egypt). Am. 109-89-7 and 141-43-5 which are cas registry numbers are also used here. Dyest. Rep., 73(1), 30-4 (English) 1984. CODEN: ADREAI. ISSN: 0002-8266. DOCUMENT TYPE: Journal CA Section: 40 (Textiles) Pretreating wool with aliph. amines (Et2NH [109-89-7], Et3N [121-44-8], PrNH2 [107-10-8], HOCH2CH2NH2 [141-43-5]) increases its accessibility in dyeing at low temp. and gives deeper, faster dyeing. The half-time of dyeing with acid and reactive dyes is lower for Et2NH-treated wool for PrNH2-treated or untreated wool. The activation energy of diffusion is 92 and 72 kJ/mol for untreated and Et2NH-treated wool, resp. .
