Abstract: A two-component epoxy resin composition, including: a resin component which includes at least one epoxy resin and at least one aldehyde, and a hardener component which includes at least one polyamine having at least one primary amino group.

Abstract: The present invention concerns a low-odor, low-viscosity hardener for epoxy resins comprising the amine of formula (I), as well as a method for thinning of hardeners for epoxy resins by adding the amine of formula (I). These hardeners harden with epoxy resins quickly and without blushing to form films of high hardness and little brittleness, even without non-incorporable thinners such as benzyl alcohol. They are especially suitable for low-emission coatings.

Abstract: A composition that includes aldimines of Formula (I). The composition can be a two-component polyurethane composition. The composition can have a long open time, but build up an early strength quickly, and in the cured state can have high tensile strength and a high modulus of elasticity. The composition can be odorless or at least low-odor before, during and after curing.

Abstract: The invention relates to compositions comprising at least one polyurethane prepolymer A with isocyanate terminal groups and at least one polyaldimine B. The polyurethane prepolymer A is produced from at least one polyol A1, optionally at least one polyol A2, in addition to polyisocyanates. The polyol A1 is a linear polyoxyalkylene polyol and has a degree of unsaturation of <0.04 mEq/g and the polyol A2 is present in a quantity of between 0 and 30 wt %, preferably between 0 and 20 wt % and in particular between 0 and 10 wt. %, in relation to the total quantity of A1+A2. In addition to the aforementioned components, a composition according to a preferred embodiment can also contain one or more of the following components: plasticizers, solvents, fillers, pigments, catalysts, rheology modifiers such as e.g. thickeners, coupling agents, dehydrators, antioxidants, light-protection agents and other conventional additives in the polyurethane industry.
