METHOD OF FORMING MONOCOMPONENT POLYURETHANE HEAT-SEALING SYSTEM Russian patent published in 2001 - IPC

Abstract RU 2171266 C2

FIELD: chemistry of polymers. SUBSTANCE: described is method of forming one component polyurethane heat-insulating system. Method comprises synthesizing isocyanate pseudoprepolymer and subsequently packaging it into open bottle, urethane formation catalyst, stabilizing agent and blocking agent being fed directly into storage bottle and subsequently packaging additional amount of low-boiling coolant or water through locking device of bottle. EFFECT: simplified packaging of system into storage bottle and greater reliability of storage of pseudoprepolymer. 3 cl, 15 ex
