STRUCTURAL ADHESIVE COMPOSITIONS Russian patent published in 2015 - IPC C09J163/00 C08G59/18 F03D1/06 

FIELD: chemistry.

SUBSTANCE: invention relates to structural adhesive compositions and more specifically to 2K structural adhesive compositions. Adhesive compositions include (a) a first component containing (i) epoxy adduct which is a reaction product of reactants comprising a first epoxy compound, a polyol and an anhydride and/or a diacid; and (ii) a second epoxy compound; (b) a second component which reacts with the first component, which contains an amino compound. The amino compound captures a polyfunctional polyether amine based on polypropylene oxide. Said adhesives can be used to join substrate materials, such as two halves of the shell of wind turbine blades.

EFFECT: invention enables to obtain adhesive compositions with a long service life and which provide sufficient bonding strength.
