  • Patent number: 10144851
    Abstract: The present invention relates to a cyanoacrylate composition having a heterogeneous curing initiator which is a hydrated calcium silicate. The composition is suitable for repairing and filling depressions, cracks, or holes in a substrate or between substrates to be bonded. It also relates to an adhesive comprising said composition, to a syringe containing it, to a method for bonding substrates, to the use of said composition, and to the use of said hydrated calcium silicate as curing agent for cyanoacrylate compositions.
    Type: Grant
    Filed: October 22, 2014
    Date of Patent: December 4, 2018
    Assignee: AFINITICA TECHNOLOGIES, S. L.
    Inventors: Ciaran McArdle, Arnau Pejoan Jiménez, Juan Andrés López Maeso, Stefano Gherardi
  • Patent number: 9670145
    Abstract: The present invention relates to a process for preparing 1,1-disubstituted ethylene monomers having general formula (I) from a compound of general formula (II) and an active methylene compound of general formula (III) using a catalytic amount of an ammonium or iminium a salt in homogeneous phase or supported on a solid substrate. Said process allows the direct synthesis of the monomers and finds application in the preparation of a wide variety of monomers. The products obtained are reactive monomers of high purity which find application in the field of fast curing adhesives.
    Type: Grant
    Filed: August 29, 2014
    Date of Patent: June 6, 2017
    Assignee: AFINITICA TECHNOLOGIES, S. L.
    Inventors: Vladimir Tchaplinski, Stefano Gherardi, Verónica De La Fuente Molina
