Applicable Base Polymer Properties
Liquid polysulfide polymers are normally associated with sealants for construction, marine, insulating glass, automotive, and aircraft industries. The liquid polysulfide polymer can be transformed from a liquid state into a solid elastomer, even at low temperatures.
Polysulfide adhesives and sealants have been successful in applications requiring good moisture, solvent and ozone resistance, and good weathering and low temperature properties. However, the chemical linkages that provide these properties also contribute to poor high temperature stability and high compression set because of stress relaxation.
