  • Polycarbamide resins for metal coating applications
    Patent number: 11041043
    Abstract: Polycarbamide coating compositions and secondary diamine curing agents used to produce the coating compositions are disclosed. Curing agent compositions comprising: (a) the reaction product of bis(4-aminocyclohexyl) methane and ethyl ester of 2-butendioc acid; and (b) the reaction product of bis(4-amino-3-methylcyclohexyl)methane and ethyl ester of 2-butendioic acid; and (c) at least one polyol are also disclosed. One aspect of the disclosure relates to a non-aqueous coating composition comprising the disclosed amine curing agents with a polyisocyanate resin. The coating compositions are suitable for use as direct to metal coatings or top coats. Methods of producing the curing agents and the coating compositions are also disclosed.

  • Use of a polyamine stream as curing agent in epoxy adhesive and flooring applications
    Publication number: 20080114094
    Abstract: An epoxy composition comprising the contact product of a filler, an epoxy resin and an amine component comprising a mixture of mono-, di-, tri- and tetra-substituted amines of structure 1 where R1 is CH2CH2CH2NH2; R2, R3 and R4 independently are H or CH2CH2CH2NH2; and X is CH2CH2 or CH2CH2CH2, in parts by weight (pbw) of 0-20 pbw mono-substituted amine, 60-95 pbw di-substituted amine, 0-20 pbw tri-substituted amine, and 0-10% tetra-substituted amine. The compositions are useful to produce coatings, adhesives, floorings, composites and other articles.
