Water-based paint composition

Water-based paint composition. Sunada, Masuyuki; Takanashi, Hirotsugu; Ishikawa, Hidenobu; Takahashi, Akikazu; Yoshino, Fumio (Dainippon Ink and Chemicals, Inc., Japan). Ger. Offen. DE 2729900 29 Jun 1978, 25 pp. (German). (Germany). CODEN: GWXXBX. CLASS: IC: C09D003-81. PRIORITY: JP 76-150759 17 Dec 1976. DOCUMENT TYPE: Patent CA Section: 42 (Coatings, Inks, and Related Products) The title coatings, with good gloss and corrosion resistance, contain water-dispersible polymers contg. 31 OH or CO2H group and water-sol. resins prepd. by polymg. alkyl 2-alkenoates or styrene derivs. 50-99.5, 2-alkenoic acids 0.5-20, and hydroxyalkyl 2-alkenoates 0-30% in the presence of unsatd. alkyds, epoxy resins, drying oils, or diene polymers. Thus, stirring dehydrated castor oil fatty acids 158, trimethylolethane 71, phthalic anhydride 102, and trimellitic anhydride 10 parts 10 h at 180° gives an alkyd resin, acid no. 35. Stirring 100 parts alkyd and 70 parts MeOCH2CH2OH at 80° while adding dropwise styrene 70, Me methacrylate 20, methacrylic acid 10, and AIBN 1 parts and stirring 3 h at 80° gives a resin, acid no. 45, which is neutralized with 20 parts Et3N. A mixt. of this resin 72, 50% aq. 3: acrylic acid-Et acrylate-styrene copolymer [25585-77-7] 100, and H2O 50 parts (viscosity 3500 cP at 25°) contg. 5% carbon black and 0.6% Co naphthenate (5%) coated on mild steel sheet is tack-free in 30 min, hardened in 10 h, and after 24 h has 60° glass 94, pencil hardness F, impact strength >25 kg/cm, Erichsen indentation 6.2 mm, and salt spray corrosion 2 mm.

(United States of America). CODEN: USXXAM. CLASS: IC: B05D003-02. NCL: 427393000. APPLICATION: US 79-91029 5 Nov 1979. DOCUMENT TYPE: Patent CA Section: 43 (Cellulose, Lignin, Paper, and Other Wood Products) Wood with good dimensional stability and water resistance is impregnated with aq. acrylic resins (mol. wt. ￡1000), high-mol. wt. acrylic resins, and optionally cosolvents, wood preservatives, and fireproofing agents. A typical compn. contained Joncryl 678 [25585-77-7] (water-sol. acrylic resin) 18.00, Acrysol 527 [66105-67-7] (low-mol. wt. acrylic resin) 2.00, 28% NH4OH 3.60, and water 76.40%.
