EPOXIDE COMPOUND FOR ADHESION AND COATING (VERSIONS) Russian patent published in 2015 - IPC C08L63/02 C08G59/40 C08G59/56 

FIELD: chemistry.

SUBSTANCE: according to the first invention, an epoxide composition contains diane epoxy and an amine hardener. The above amine hardener in the composition is presented by a reaction product of polyaminoalkylphenol of formula (1) wherein n is equal to 1-7, and cyclocarbonate containing cyclocarbonate groups 18.67-25.00 wt %, epoxy oxygen 0.13-1.38 wt %, hydroxyl number 11.4-12.5 mgCoH/g on the basis of oxidised rape oil containing epoxy oxygen 5.75-6.22 wt %, hydroxyl number 13.6-14.6 mgCoH/g, iodine number 3.7-12.3 g I2/100 g. According to the second version, the epoxide composition contains diane epoxy, cyclocarbonate and an amide hardener. Cyclocarbonate in the composition is presented by above cyclocarbonate on the basis of oxidised rape oil. The above amine hardener is presented by above polyaminoalkylphenol of formula (1).

EFFECT: reducing viscosity of the epoxidic composition, prolonging its gelatination for using the composition on greater surfaces, increasing specific impact strength, breaking strength and adhesion strength.
