FIELD: chemistry.
SUBSTANCE: present invention relates to a (meth)acrylate/aspartate amine curing agent which contains the product of a reaction between (a) polyamine, (b) dialkylmaleate and/or dialkylfumarate and (c) (meth)acrylate and production method thereof. The invention also describes polyurea which contains the product of the reaction between said curing agents and isocyanate, coating compositions which contains such polyurea, and substrates coated with such compositions.
EFFECT: obtaining amine curing agents which are sufficiently reactive but which ensure appropriate application life and endow final compositions in which said curing agents are used with the required characteristics, resistance to damages caused by corrosion, wearing, impact, effect of chemical substances, UV radiation, heating and other surrounding medium factors.
