Abstract: Secondary diamine N,N′-dialkyl methylcyclohexanediamine acts as a reactive diluent for curable epoxy resin compositions. The addition of this compounds significantly reduces the initial viscosity of the epoxy resin composition while the resulting cured epoxy resin exhibits comparable favorable mechanical, chemical resistance and thermal properties such as low water uptake and high glass transition temperatures. Such compositions are particular suitable for manufacturing of composites with high mechanical and heat resistance properties by the means of resin transfer molding (RTM), vacuum aided resin transfer molding (VARTM) or infusion technology.

Abstract: A method for preparing a thermoplastic polyoxazolidone, the method including catalytically reacting one or more aromatic diisocyanates and one or more diepoxides, wherein the one or more diepoxides comprise one or more 2-phenylpropane-1,3-diol diglycidyl ether derivatives. The one or more diepoxides further contain one or more diglycidyl ethers of aromatic diols.

Abstract: The present invention relates to the polyamines N,N′-diaminopropyl-2-methyl-cyclohexane-1,3-diamine and N,N′-diaminopropyl-4-methyl-cyclohexane-1,3-diamine and mixtures thereof, to the use thereof as curing agents for epoxy resin and to a curable composition comprising epoxy resin and these polyamines. Even at low temperatures this curing agent/the corresponding curable composition cures rapidly and is early-stage water resistant and is thus especially suitable for floor coatings. The invention further relates to the curing of this composition and the cured epoxy resin obtained by curing of this composition.
