Thioplastâ„¢ EPS Resins Epoxy-Terminated Liquid Polysulfides
Thioplast™ EPS resins are epoxy-terminated, low-viscosity liquid polysulfide polymers derived from the SH-terminated polysulfide polymer Thioplast™ G. Thioplast™ EPS resins are telechelic polymers with outstanding properties which combine the flexibility of conventional Thioplast™ G liquid polysulfide polymers with the toughness of standard Bisphenol A/F-Epoxy based resins. Thioplast™ EPS resins can be used in formulations together with other epoxy resins to increase flexibility, adhesion, aging and weathering and to improve chemical resistance. Thioplast™ EPS resins have been specifically developed for use in high-performance coatings, sealants, and adhesive formulations for both interior and exterior use.

Liquid Polysulfide Polymers with reactive SH-End groups Polymer structure
Introduction
Liquid polysulfide polymers are the oldest specialty elastomers. They are low- to high viscous polymers with highly reactive terminal thiol end-groups, characterized by outstanding solvent and chemical resistance, great electrical properties, low-temperature flexibility, ultraviolet (UV) light, oxygen, and ozone resistance, highly impermeable to many gases and moisture, good adhesion properties, and flex-crack resistance.
Liquid polysulfide polymers are used in the form of highly flexible joint sealants, adhesives, and protective coatings. Properties that make liquid polysulfide polymers useful are:
