EPOXIDE COMPOUND USED FOR GLASS-REINFORCED PLASTICS Russian patent published in 2009 - IPC C08L63/02 C08L63/10 B32B27/38 B32B17/10 

FIELD: construction industry.

SUBSTANCE: invention refers to epoxide compound intended for being used as binding agent for glass-reinforced plastic tubes with operating temperature of up to +120°C. Compound contains the following components at their ratio, in parts by mass: resin 100, isomethyltetrahydrophthalic anhydride hardener 73.6-75.2, and promoter of 2,4,6-tris(dimethylaminomethyl)-phenol - Alkofen 1.38-1.40. Product of ED-20 epoxide resin interacting with a mixture of isomeric products based on diphenylmethane diisocyanate at stoichiometric ratio of NCO-groups to OH groups is used in the compound as resin.

EFFECT: invention allows improving ultimate bending strength and thermal deformation of compound.
