Applicable Base Polymer Properties

Because of their thermosetting molecular structure, epoxy grout / adhesives exhibit excellent compressive and tensile-shear strength but poor peel strength unless modified with a more resilient polymer. Epoxy grouts 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 grouts and adhesives. Epoxy resins have no evolution of volatiles during cure and are useful in gap-filling applications.

Resulting Properties

Grout is a fluid form of concrete used to fill gaps. It is used in construction to embed rebars in masonry walls, connect sections of pre-cast concrete, fill voids, and seal joints such as those between tiles.

In the tile grout formulation, NX-8101 exhibits excellent compression strength and fast hardness development with extended working time. Use of Ultra Lite 513 instead of NY 748 offers comparable performance.
