Thioplast - excellence in sealants, adhesives and coatings

Your polymer of choice for gas-tight, weatherable, chemical resistive sealants & adhesives and low-temperature impact resistant coatings.

We are the largest producer of liquid polysulfide polymers worldwide. Thioplast-based products are characterized by pronounced chemical resistance, weatherability, gas-tightness and flexibility even at very low temperatures.

Formulators enjoy the freedom to use thiol-terminated Thioplast G or epoxy-terminated Thioplast EPS polysulfides with a large range of curatives from oxidants to epoxides.

Top manufacturers of high-performance products in the building and construction, aerospace and oil and gas industry rely on Thioplast polysulfides.

Thioplast - polysulfides

Thioplast G4

The low viscosity combined with Thioplast's unique combination of features like chemical resistance and low-temperature flexibility appeals to high-performance coating manufacturers of all industry branches to protect metal or concrete surfaces, floors, or pipelines. Formulators tailor properties like pot-life, tensile strength, adhesion and elongation at break by choosing from various compatible plasticizers, fillers and other additives. The viscosity, degree of branching and SH content can easily be adjusted by blending this grade with others to generate your tailored Thioplast polysulfide.

Thioplast EPS70

Nouryon's fast-curing epoxy-terminated polysulfide polymer. Thanks to the aromatic end-groups, this grade is curing quickly, even at room temperature. 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, chemical 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.
