  • Polyamide curative from substituted amine and dimer fatty acid or ester
    Patent number: 8293863
    Abstract: The present invention provides polyamide curing agent compositions comprising the reaction products of (1) multifunctional amines of structure 1 where R1 is CH2CH2CH2NH2; R2, R3 and R4 independently are H or CH2CH2CH2NH2, and X is CH2CH2 or CH2CH2CH2 with (2) dimer fatty acids, optionally in combination with monofunctional fatty acids, the reaction product preferably comprising at least 15 wt % tetrahydropyrimidine-containing components. The curing agent compositions are useful for crosslinking epoxy resins to produce coatings, adhesives, floorings, composites and other articles.
    Type: Grant
    Filed: February 9, 2007
    Date of Patent: October 23, 2012
    Assignee: Air Products and Chemicals, Inc.
    Inventors: Gamini Ananda Vedage, Stephan Francis Monaghan, Williams René Edouard Raymond, Michael Ian Cook, Michael Paul Popule
