FIELD: chemistry.
SUBSTANCE: invention relates to curable under actinic radiation compositions containing polythiols and urethane/urea-containing polyalkenyl prepolymers. Disclosed is a composition for use as aerospace coatings and sealants, comprising a urethane-containing and/or urea-containing polythiol (containing at least one urethane or urea group in polythiol) and a urethane-containing polyalkenyl prepolymer, a urea-containing prepolymer or a combination thereof. Invention also discloses sealant and sealing system containing said composition, sealing method of part using said sealant and corresponding part.
EFFECT: technical result is fast hardening of disclosed composition.
