COATING COMPOSITION Russian patent published in 2005 - IPC

FIELD: polymers, in particular resin compositions based on liquid hydrocarbon rubber useful in building industry for manufacturing of roofing and insulating coatings.

SUBSTANCE: claimed composition contains law molecular rubber isoprene-butadiene copolymer in monomer ratio of 20:80, having molecular weight of 3000-3500 and hydroxyl content of 0.7-1.1 mass %; polyisocyanate, waste from polycaproamide production, catalyst for urethane formation. Additionally composition may contain component moisture absorber, filler, plasticizer solvent, law molecular alcohol, antiaging agent pigment and surfactant.

EFFECT: coatings with decreased moisture absorption and increased aging resistance.
