  • Method for preparation of a moulded composite from a bulk moulding compound
    Patent number: 11780176
    Abstract: A bulk moulding compound comprising one or more cyanate ester, a catalyst, a filler and reinforcement fibres is provide, whereby the one or more cyanate ester is independently selected from a difunctional cyanate ester compound and/or a polyfunctional cyanate ester and mixtures of these cyanate esters. Furthermore, the catalyst is independently selected from the group consisting of 4,4? methylene-bis(2,6-diethylaniline) (M-DEA), 4,4?-methylene-bis(3-chloro-2,6-diethyl¬aniline) (M-CDEA), aluminum(III)acetylacetonate, and mixtures thereof.
    Type: Grant
    Filed: February 12, 2021
    Date of Patent: October 10, 2023
    Assignee: Arxada AG
    Inventors: Gaetano La Delfa, Stefan Ellinger, Roger Mazotti, Marcel Sommer, Stefano Licari, Sandro Landonio
  • NOVEL COMPOSITIONS WITH IMPROVED CHARACTERISTICS
    Publication number: 20230265287
