Thioplast EPS70

Back to search


Thioplast EPS is an epoxy-terminated polysulfide type with low viscosity. The introduction of epoxy-termination into the polysulfide structure results in the formation of a unique polymer which combines the excellent properties of Nouryon's polysulfides Thioplast G with the most desirable features of epoxy-resin systems.

  • Applications

    Thioplast EPS70 could be used in application of flexible, crack bridging and corrosionresistant coatings for concrete and steel. Furthermore, Thioplast EPS70 is applied in formulations of adhesives, sealants and is being used as flexible reactive diluents for high viscos Epoxies.Thioplast EPS70 combines the outstanding chemical / physical properties of Thioplast G, liquid Polysulfide polymers, with the benefits of the Epoxy-chemistry. Further advantages of Thioplast EPS70 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. Thioplast EPS70 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 EPS70 is chemically compatible with most of Bisphenol A, A/F, F and Novolac-Epoxies.
