Polymer Systems for Rapid Sealing of Aircraft Structures at Low Temperature.

Abstract

Materials examined for low temperature, rapid curing, fuel and water resistant sealants included hot melts, UV activated, moisture curing, and anaerobic polymers. Two component polymers utilizing urethane cures, oxidation, and mercaptan-epoxy additions were evaluated: Epoxy cures of mercaptan terminated polythioethers gave excellent low temperature cures along with practical application times. Physical and chemical properties were examined and found to essentially meet requirements of MIL-S-85420 (AS). Storage stability was excellent.
