Eponext® Epoxy Poly Sulfide Hybrid Resin (EPS)

High flexible, Impact resistance

Eponext® EPS series are a new generation of hybrid resins by medium viscosity, designed to provide a high degree of flexibility and impact resistance for a majority of floorings, coatings, composites, Adhesives and sealants applications.

Eponext® EPS is epoxy-terminated, medium viscosity poly sulfides. The introduction of epoxy-termination into the poly sulfide structure results in formation of a unique polymer which combines the excellent properties of Eponext poly sulfides with desirable features of epoxy-resin systems.

Eponext® EPS resins can be used in formulations together with other epoxy- resins to increase flexibility, adhesion, impact resistance, aging and weathering and to improve chemical resistance that some of them appropriated for unfilled systems.

Eponext ® EPS resins have been specifically developed for use in high performance coatings, sealants and adhesives formulations for both interior and exterior use.

All types are particularly well suited for heavy-duty surface applications on metal and concrete.

In addition, Eponext® EPS resins are cured with common epoxy amine hardeners.

There is no need to use curing agents containing heavy metals. They show unique self-repair and crack-bridging behavior.

Eponext® EPS resins can act as a high potential flexibilizer in classical Bisphenol A/F Epoxy-formulations.

Properties

Eponext® EPS resins present a number of special properties:

• Good adhesion on many materials

• Adjustable flexibility

• High impact resistance

• Chemical resistance to a number of diluted acids, alkalis and organic solvents

• Good wetting of pigments

• Excellent self-leveling

• Curing at ambient temperature

These hybrids can be cured with a wide range of curing agents

Curing of Eponext® EPS resins

As a rule, epoxydized polysulfide are formulated as two component systems and are cured at ambient temperature in the presence of a catalyst.

For example, component A could contain the Epoxy- or Eponext® EPS resins compound and component B could contain a compound with active hydrogen and a catalyst.

Preferred catalysts for curing Eponext® EPS resins are amines:

• Aliphatic amines

• Cycloaliphatic amines

• Amidoamines

• Aromatic amines

• Polyamides
