  • Floor coating composition and floor coating composition additive
    Patent number: 7378381
    Abstract: To provide a floor coating composition and floor coating composition additive. It is possible to improve the leveling performance, mopping performance, and other properties of a floor coating composition over those obtained with a conventional tributoxyethyl phosphate leveling agent by adding to a floor coating composition 1) a (C7-C10) aliphatic monocarboxylic acid monoester of a diol, or 2) a (C7-C10) aliphatic monocarboxylic acid monoester or diester of a triol.
    Type: Grant
    Filed: April 21, 2006
    Date of Patent: May 27, 2008
    Assignee: Rohm and Haas Company
    Inventors: Zenichi Arai, Jun Iizuka, Tomoaki Ogata, Shigeo Ueda

  • Emulsion polymer composition
    Patent number: 5869569
    Abstract: An emulsion polymer composition having fast drying properties that provides floor polish coating materials having superior resistance to black heel marks, resistance to scuffing, resistance to abrasion, adhesion, and resistance to cleaning agents characteristics, is obtained from a film forming emulsion polymer composition comprising from greater than 60 wt % to 95 wt % of a first emulsion copolymer having a glass transition temperature within the range of from 10.degree.-100.degree. C., and from 5 wt % to less than 40 wt % of a second emulsion copolymer having a glass transition temperature that is lower than that of the first emulsion copolymer and is within the range of from 0.degree.-50.degree. C.
