EPOXY COMPOSITION Russian patent published in 2005 - IPC

FIELD: epoxy composition technology, in particular production of hot formed fast-curing epoxy compositions.

SUBSTANCE: claimed composition contains at least one epoxydianic resin or mixture thereof with resins comprising one or two epoxy groups; anhydrite or polyanhydrite or mixture thereof as curing agent; and curing catalyst. As curing catalyst composition contains quaternary ammonium salt or mixture of quaternary ammonium salts of general formula: , wherein R₁, R₂, and R₃ are aliphatic hydrocarbon radical; at least one R₁, R₂, and R₃ has 8-20 of carbon atoms, and the rest ones has not more than 2 of carbon atoms; R₄-H, CH₃, C₂H₅, benzyl; A^- is Cl^- or Br^-. Compositions of present invention are useful as binder in composite (e.g., reinforced plastics) production. Invention may be used in automobile, spacecraft, electric industry, etc.

EFFECT: epoxy composition with improved technological and operating characteristics; decreased catalyst consumption; catalyst with improved surfactant properties; increased filler assortment.
