Development of High Temperature, Improved Performance Polythioether Sealants, Coatings and Adhesives

Abstract

Fluid, heat, and electrical properties of polythioether formulations were measured. Effects of sulfur content, curing agents, and stabilizers on properties were examined for high temperature aircraft sealant development. A three to ten fold increase in retention of elastomeric properties at elevated temperatures to 400 deg. F was observed versus current sealants. The materials' unique characteristics also suggest development of polythioether urethanes for fuel and fluid resistant coatings and lining, electrical sealants and anticorrosion barriers. Keywords: Polythioethers, high temperature, fuel, water, electrical properties, sealants, coatings, compositions.
