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.

These are:

  • Good weathering properties
  • Excellent adhesion to most surfaces
  • Primerless adhesion on many substrates
  • Elastic behavior withstanding vibrations and joint movement
  • Reduced tension in material joints
  • High impact resistance, including low temperatures
  • High stability with regard to thermo cycling
  • Chemical resistance to oil, fuels, dilute acids, alkalis, solvents and sea water
  • High speed curing at ambient temperature
  • High flexibility

Depending on the field of application, Thioplast™ EPS can either be used alone or in combination with conventional aromatic glycidyl ethers and other epoxies.


  • Adhesives for steel and aluminum, concrete and automotive
  • Corrosion protection coatings for marine, chemical plants equipment, pipelines etc.

Containment coatings made with epoxidized Thioplast™ EPS prevent fuel, chemicals and solvents from penetrating into contaminating soil. These coatings can also protect windmills, pipelines and ships from corrosion. As a non-toxic material Thioplast™ EPS is ideal for contact with food and potable water.
