Formulation Guide
EPOXY.COM PRODUCT #6885 MMA requires the addition of EPOXY.COM Product #695 MMA HARDENER to initiate the hardening process. The amount of hardener must be adjusted based on surface temperature (see table below). At temperatures below 40°F, EPOXY.COM PRODUCT # 696 MMA COLD TEMPERATURE ACCELERATOR must be used in addition to the amount of hardener used at the 40°F or 30°F level.

Note: Decrease the hardener content as needed to increase working time, minimum 2 ounce per gallon is needed for proper curing at >60°F. Important: At 65-80°F, 2 oz. by volume per gallon is typical. For faster cure time and/or colder temperatures, increase Epoxy.com Product #696 according to instructions, however, resin ambering will develop at 3 oz. and greater which will be noticeable with light colors or clear systems (quartz, chip systems). Cured resin will have some resilience.

APPLICATION
EPOXY.COM PRODUCT #6885 MMA and hardener powder are mixed and blended with aggregates for 3 minutes until no lumps are present. Apply to the fully cured primed surface using a cove trowel or flat trowel. EPOXY.COM PRODUCT #6885 MMA Cove Base Mortar must be sealed/top coated with the same EPOXY.COM MMA Sealer used for the floor system.

STORAGE
Store in a cool and dry place, below 80°F, out of direct sunlight. Do not store near open flame or food. Shelf life is 6 months in the original unopened containers. After extended storage: Additives and fillers can separate with storage, materials should be inspected for any visible signs of settlement, polymerization, or paraffin coagulation (clumps, strands). Thoroughly mix pails or drums (use a drum mixer, do not rely on rolling drum on floor) and pour into new containers to inspect resin before use.
