FIELD: chemistry.
SUBSTANCE: invention relates to a sealant composition containing a sulfur-containing prepolymer with thiol terminal groups, a curing agent containing two or more terminal groups capable of reacting with thiol groups, and an ionic liquid-based catalyst used for sealants in the aerospace industry.
EFFECT: use of catalysts based on ionic liquids results in obtaining compositions of curable sealants, having excellent viability and high rate of curing.
