(at 75°F or 25°C and 50% RH)

To touch 4-6 hours
Fully dry 6-10 hours
Light traffic 18+ hours
Full cure 7-14 days

APPLICATION TEMPERATURE:
65°F (18°C) and 80°F (26°C) and between 30% – 70% relative humidity.  DO NOT apply coatings unless the surface temperature is more than five degrees over the dew point.

MIXING AND APPLICATION INSTRUCTIONS

1) PRODUCT STORAGE:   Materials should be stored in original un-opened containers indoors between 65°F (18°C) and 90°F (32°C) and at or below 75% RH.

2) GENERAL SURFACE PREPARATION:  All surfaces must be sound, dry, clean and free of oil, grease, dirt, mildew, form release agents, curing compounds, loose and flaking paint and other foreign substances.  Surface dirt, grease, oil, and contaminates must be removed by detergent scrubbing and rinsing with clean water.

Shot blasting or grinding the surface is the preferred method of preparation when applied to bare concrete surface.  If the concrete has been treated or sealed, proceed with complete removal process.   The success of industrial diamond grinding as a concrete preparation method will vary depending on technique and the hardness of the concrete

If contaminates of oils, silicones, mold release agents, and/or others are present, HB-97.2 ESD top coat may fisheye or delaminate from the surface. Surface contaminates should be removed with a suitable detergent prior to application. Solvent cleaning of silicone contaminates may make the situation worse; please contact Staticworx for additional recommendations.

MOISTURE AND VAPOR/CONTAMINATION

Moisture and vapor transmission rates are dynamic in nature and may change over time. Initial testing does not guarantee future results. Staticworx requires that all concrete slabs are tested using in-situ probes per ASTM F-2170 and with calcium chloride tests per ASTM F-1869. If the relative humidity of the concrete substrate is over 75% (per ASTM F-2170) or 3lbs/1,000ft²/24 hours (ASTM F-1869), contact Staticworx for a moisture mitigation recommendation prior to product use.

If there is no known vapor barrier or the vapor barrier is inadequate, there is an elevated risk of bond failure. Other factors including the migration of oils, chemicals, excessive salts or Alkali Silica Reaction (ASR) from the concrete may also elevate the risk of adhesion difficulties. Contact Staticworx for approved mitigation treatments.

Electrical Grounding   Installing HB-97.2 Primer between the concrete surface and HB-97.2 top coat is mandatory. The coating must be grounded to an earth ground once every 1,000 square feet for proper static dissipation. The EOS/ESD Association provides instruction for proper grounding of ESD equipment and floors. See the following guide on how to properly ground the HB-97.2 Epoxy Primer for your floor coating system:  HOW TO GROUND ESD COATINGS

MIXING INSTRUCTIONS: Premix the 2 gallon pail of Part A with a small mixing paddle attached to a drill in order to re-disperse possible settling that may have occurred during storage and shipping. Then add the color pack and mix together until a homogenous color is obtained throughout the 2 gallon pail. Next, empty the entire contents of Part A and color into a separate mixing container which will accommodate the 1.8 gallon mixed volume. Be sure to completely scrape our entire contents of the 2 gallon pail. Finally, add entire contents of Part B and mix all components for 2-3 minutes at slow speed. Staticworx recommends the use of a Jiffy® ES blade to filter the entire mix prior to application to remove agglomerates of particulate that may have not been thoroughly mixed

Improper mixing may result in product failure.

For best mixing results and proper blending of parts A and B, recommend a Jiffy Mixer style drill mixer.

TEMPERATURE AND HUMIDITY
During the application and curing of the coating, the substrate temperature, material temperature, and room conditions must be maintained between 65°F (18°C) and 80°F (26°C). Relative Humidity (RH) should be limited to 30- 70%. DO NOT apply coatings unless the surface temperature is more than five degrees over the dew point.

PRODUCT APPLICATION: Apply HB-97.2 ESD top coat at a rate of 3.5-5 mils 285ft² – 410ft² per gallon) to the floor surface using a notched squeegee. If aggregate is utilized, HB-97.2 top coat must be pan rolled and NOT squeegeed. Using a squeegee will produce lines of aggregate that will not roll out evenly. Back roll the wet coating using a 3/8 inch nap roller. Care should be taken to overlap and cross lap. One coat of HB-97.2 top coat is all that is required to achieve the appropriate ESD properties. Be sure to sufficiently roll out the HB-97.2 top coat to achieve an even film thickness throughout the entire area. Excessively thick areas (>5 mils) will exhibit slightly more gloss whereas thinner areas (<3.5 mils) will tend to produce a flatter/matte finish. Unlike most other ESD coatings, HB-97.2 will not foam and produce bubbles from rolling. The material must be rolled enough so that the reflection is uniform, showing little to no signs of overlap, pooling, or contrasting thick and thin areas.

Material must be mixed, applied, and finish rolled within 20 minutes of mixing. Failure to achieve this may result in inconsistent or non-compliant electrical performance and may also provide an inconsistent finish. Do not combine multiple kits together unless this time table can be easily met.

Material applied too heavily may blister or can be soft during curing. Too little material may produce a non-uniform look and affect electrical performance. Industry best practice is to measure and grid the floor to be sure of proper application rate.

MAINTENANCE GUIDELINES:  Allow floor coating to cure for at least 7 days before cleaning by mechanical means (i.e. sweeper, scrubber, disc buffer). Increased life of the floor will be seen with proper maintenance and will help maintain a fresh appearance. Regularly sweep to avoid retention of dirt and grime which can quickly dull the finish, decreasing the life of the coating. Spills should be removed as quickly as possible as certain chemicals may stain and can permanently damage the finish. Only soft nylon brushes or white pads should be used on your new floor coating. Premature loss of gloss can be caused by hard abrasive bristle Polypropylene (Tynex®) brushes.

Caution!  Some cleaners may affect the color of the floor installed. 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.

DAMAGES AND REPAIRS

Heavy objects dragged across the surface will scratch any floor coating. Avoid gouging or scratching the surface. Staticworx recommends protecting the floor with plywood, Masonite, or Ram boards whenever heavy equipment is being moved in or out of the space. Pointed items or heavy items dropped on the floor may cause chipping or concrete chip damage. Plasticizer migration from rubber tires can permanently stain the floor coating. If a rubber tire is planned to set on the floor for a long period of time, place a piece of acrylic sheet between the tire and the floor to prevent tire staining. Rubber burns from quick stops and starts from forklifts and lift trucks can heat the coating to its softening point, causing permanent damage and marking. Repair gouges, chips, and scratches as soon as possible to prevent moisture and chemical under cutting and permanent damage to the floor coating.

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. Dependent on actual complete system application, surface may be slippery, especially when wet or contaminated; keep surface clean and dry.

LIMITATIONS:

  • Substrate temperature must be 5°F above dew point.
  • All new concrete must be cured for at least 30 days prior to application.
