METHODS OF PRODUCING CURED SEALANTS USING ACTINIC RADIATION AND CORRESPONDING COMPOSITIONS Russian patent published in 2019 - IPC C08L81/02 C09K3/10 C09J181/02 C08G75/02 

Abstract RU 2705368 C2

FIELD: chemistry.

SUBSTANCE: present invention relates to a non-cured sealant, a cured sealant, a method for production thereof and an aerospace aircraft. Said composition contains a polythioether having terminal thiol groups, polyene containing a polyvinyl ether, and a hydroxy-functional vinyl ether. Method of producing a cured sealant involves depositing said composition onto a substrate and exposing actinic radiation to obtain a cured sealant.

EFFECT: obtained compositions are stable during storage and are capable of fast hardening when deposited on a substrate to obtain a cured sealant, having fuel resistance, low-temperature flexibility, low curing time and resistance to high temperatures.
