Thioplast EPS25

Product Line Thioplast - polysulfides

Nouryon's worldwide unique, purely aliphatic epoxy-terminated polysulfide polymer. Thanks to the aliphatic polymer backbone, this type is particularly suitable for outdoor use. As the other Thioplast EPS grades, this grade combines the excellent properties of polysulfides with the most desirable features of epoxy-resin systems to yield: excellent primerless adhesion to many surfaces (e.g. steel, aluminum or concrete), high impact resistance, even at low temperatures, high thermo cycling stability, dhemical resistance to oil, fuels, dilute acids, alkalis, solvents and sea water, very high flexibility, good weathering properties and corrosion protection. Thioplast EPS can either be used alone or in combination with conventional epoxy resins to produce high-performance heavy-duty adhesives and coatings. Manufacturers from the automotive, marine or chemical industries rely on Thioplast EPS grades.

  • Applications

    Thioplast EPS25 could be used in application of flexible, crack bridging and corrosionresistant coatings for concrete and steel. Furthermore, Thioplast EPS25 is applied in formulations of adhesives, sealants and is being used as flexible reactive diluents for high viscos Epoxies. Thioplast EPS25 combines the outstanding chemical / physical properties of Thioplast G, liquid Polysulfide polymers, with the benefits of the Epoxy-chemistry. Further advantages of Thioplast EPS25 are; improve the flexibility of standard Bisphenol A, A/F and F based Epoxies, improve the impact and thermal shock resistance, excellent water and corrosion resistance, resistance to a variety of aggressive chemicals, fuels and other oil products. Furthermore Thioplast EPS25 is used as additive in two-component Epoxy-systems. Curing at room and elevated temperature (max. temp. approx. 150C/300F), typical curatives are aliphatic and cycloaliphatic amines. Thioplast EPS25 is chemically compatible with most of Bisphenol A, A/F, F and Novolac-Epoxies.
