Applicable Base Polymer Properties

Because of their thermosetting molecular structure, epoxy adhesives exhibit excellent tensile-shear strength but poor peel strength unless modified with a more resilient polymer. Epoxy adhesives offer excellent resistance to oil, moisture, and many solvents. Low shrinkage on curing and high resistance to creep under prolonged stress are characteristics of many high quality epoxy adhesives. Epoxy resins have no evolution of volatiles during cure and are useful in gap-filling applications.

Resulting Properties

This formulation illustrates the use of a water dispersible epoxy resin system as a binder for trowel-applied, decorative and protective floor toppings. Water is added to the resin/ converter mix to lower viscosity and impart non-stick troweling characteristics without the disadvantages of odor, fire hazard and health hazard associated with many organic diluents and solvents. Extended pot life and water cleanup of tools are additional convenience features. Practical cure rates are achieved at substrate temperatures as low as 18 °C. The ceramic coated, quartz granule aggregate affords a wide selection of colors for decorative flooring applied in institutional buildings, schools, hospitals, restaurants, and offices.
