EPOXY COMPOSITION Russian patent published in 2024 - IPC C08L63/02 

FIELD: polymer materials.

SUBSTANCE: invention relates in particular to polymer composite materials for general and special purposes based on epoxy resin, which can be used both to produce independent composites and as binders for the manufacture of fiberglass for boats. An epoxy composition is proposed containing “ЭД-20” epoxy resin, a hardener and thermoplastic polyurethane, while the composition contains triethylenetetramine as a hardener, and T-ECOPUR brand polyurethane, pre-dissolved in triethylenetetramine at 50°C, as a thermoplastic polyurethane, with the following ratio of composition components, parts by weight: epoxy resin “ЭД-20” - 100.0, T-ECOPUR polyurethane - 0.5-2.0 and triethylenetetramine - 10.0.

EFFECT: increase in physical and mechanical characteristics, hydrophobicity and abrasion resistance index.
