  • Patent number: 11401486
    Abstract: There is provided a solvent composition which is a stable solvent composition which is excellent in solubility of various organic substances, has a sufficient drying property, and has no adverse effect on a global environment, is stabilized not to decompose, and moreover suppresses metal corrosion under coexistence with metal, and which can be used without having an adverse effect on articles of various materials such as metal, plastic, and elastomer in a wide range of industrial uses such as cleaning and dilution coating uses. A solvent composition including: a solvent (A) including (D-1-chloro-3,3,3-trifluoro-1-propene; and a stabilizer (B) consisting of HCFC whose boiling point at normal pressure is not lower than 30° C. nor higher than 60° C.
    Type: Grant
    Filed: September 18, 2020
    Date of Patent: August 2, 2022
    Assignee: AGC Inc.
    Inventors: Masahiko Nakamura, Hidekazu Okamoto, Masaaki Tsuzaki, Hiroaki Mitsuoka, Satoko Itoh
