  • Patent number: 10253225
    Abstract: The invention relates to structural adhesive compositions and more particularly to two-component (2K) structural adhesive compositions. The two components chemically react to bond structural surfaces. N-(3-Aminopropyl)cyclohexylamine (APCHA) has been found to be an improved curing agent for use with epoxy resins in 2K adhesive compositions. APHCA exhibits favorable features including viscosity, pot life and reactivity, and adhesive and thermal performance after curing with epoxy resin. These features and its unique chemistry allow the use of APCHA in curing agent formulations for structural adhesives, in particular wind turbine blade adhesives. APCHA solves issues with viscosity build-up, working time, through-cure, compatibility and adhesive performance that cannot be addressed with the commonly used amine formulations.

  • Patent number: 7989553
    Abstract: Disclosed is a novel epoxy-amine composition modified a hydroxyalkyl urethane, which is obtained as a result of a reaction between a primary amine (C1) and a monocyclocarbonate (C2), wherein modifier (C) is represented by the following formula (1): wherein R1 is a residue of the primary amine, R2 and R3 are the same or different and are selected from the group consisting of H, alkyl, hydroxyalkyl, and n satisfies the following condition: n?2. Diluents, pigments and additives can be used. Doping with the hydroxyalkyl-urethane modifier imparts to the cured composition superior coating performance characteristics, such as pot-life/drying, strength-stress, bonding, appearance, resistance to abrasion and solvents, etc., in a well-balanced state.
