718 Fast Set HB HG Epoxy

718 HB HG Epoxy

High Build, High Gloss, 100% Solids, Epoxy

DESCRIPTION

718 HB HG Epoxy is a multidesign epoxy resin with options for quartz, flake,silica, or aluminum oxide broadcast into the surface providing a long-lasting High Gloss finish up to 3” in thickness for fill or transitional floors. Its design features make it an ideal system for many applications.

Usage Area

• Laboratories • Food Processing Plants • Dairy Plants • Schools, Prisons, and Jails • Meat Packing and Poultry Plants • Animal Care Areas • Commercial Kitchens • Hospitals
• Pharmaceutical Plants • Food Ingredients Plants • Shower, Locker Room, and Break Rooms
• Clean Rooms • Garages

Packing and Storage

Continuous storage should be between 60°F and 90°F. 718 HB FS Epoxy is available in 15 gallon pre measured kits consisting of pre diluted epoxy resin (Part A) and a curing agent (Part B) to provide chemically resistant coating with a mix ratio of 2 Parts A to 1 Part B. 718 HB HG must be stored in an area as to bring the material to normal room temperature before using. The shelf life is one year from ship date in the original unopened container

Colors

Tinting is performed by the installer on site for all kit sizes using the EP (Epoxy Pigment). Pre tinted are kits are available upon request.

Floor Cleaning

718 HB HG is designed to be maintenance-free flooring. The high degree of chemical resistance imparted by the urethane binder allows this system to be cleaned with strong acid or caustic cleaners without damage. Test each cleaner in a small area, utilizing your cleaning technique. If no ill effects are noted, you can continue to clean with the product and process tested.

Safety Precautions

For all information regarding product use and correct product disposal please refer to Safety Data Sheet.

Mixing and Application Instructions

Surface Preparation

Surface preparation will vary according to the type of complete system to be applied. For a one or two coat thin build system (8-12 mils dry) we recommend either mechanical profiling or acid etching until a suitable profile is achieved. For a complete system build higher than 10 mils dry, we recommend a fine brush blast (shot blast). All dirt, oil, dust, foreign contaminants and laitance must be removed to assure a trouble-free bond to the substrate. A test should be made to determine that the concrete is dry; this can be done by placing a 4′ X 4′ plastic sheet on the substrate and taping down the edges. If after 24 hours, the substrate is still dry below the plastic sheet, then the substrate is dry enough to start coating. The plastic sheet testing is also a good method to determine if any hydrostatic pressure problems exist that may later cause disbonding.

Product Mixing

This product has a two to one mix ratio by volume- merely mix 2 gallons of part A with 1 gallon of part B. After the two parts are combined, mix well with slow speed mixing equipment such as a jiffy mixer until the material is thoroughly mixed and streak free. Avoid whipping air into the coating. Improper mixing may result in product failure.

Product Application

718 HB HG is generally applied at a thickness of 12 mils to l/8″ per coat, however up to 3″ can be applied as a mutual blend. Apply between 65°F – 90°F with relative humidity below 90%. Application temperature can be as low as 45 degrees F with optional Accelerator. Thinning is not required. The mixed material can be applied by brush or roller. Maintain temperatures within the recommended ranges during the application and curing process. Properly prime the substrate. It is best to maintain a wet edge to avoid roller marks. Direct sunlight or high temperatures may cause visible roller marking during application. Too thick of an application may result in solvent entrapment and product failure.

Recoat or Top coating

Multiple coats of this product are acceptable. The information on the front side are reliable guidelines to follow. However, it is best to test the coating before recoating or top coating. This can be done by pressing on the coating with your thumb to verify that no fingerprint impression is left. If no impression is created, then the recoat can be started. Always remember that colder temperatures will require more cure time for the product before recoating can commence. Before recoating or top coating, check the coating to insure no contaminants exist. If a blush or contaminants are present on a previous coat, remove with a standard detergent cleaner. When recoating this product with subsequent coats of the urethane, it is advisable to apply the recoat before 24 hour passes. Also, it is advisable to degloss the previous coat to insure a trouble-free bond.

Cleanup

Use Keytone Solvents

Restrictions

Restrict the use of the floor to light traffic and non-harsh chemicals until the coating is fully cured (see technical data under full cure). It is best to let the floor remain dry for the full cure cycle.
