HB-97.2 ESD Static Conductive Heavy Duty 100% Solids Epoxy Primer | ANSI/ESD S20.20-2014

HB-97.2 ESD Conductive Epoxy Primer is a two-component 100% solids high build epoxy resin moisture tolerant coating system that can be applied as a clear or pigmented floor primer or coating. It is designed specifically to be used as an ESD conductive primer prior to application of the HB-97.2 ESD Top Coat as a heavy wear ESD protective coating system in a wide variety of heavy duty commercial and industrial environments where the harmful effects of electrostatic discharge must be avoided. When used together, the HB-97.2 ESD Urethane Top Coat  and HB-97.2 ESD Epoxy Primer Coat complete an ESD protection, static conductive system that can be used where significant commercial and industrial forklift, pallet jack, heavy cart and foot traffic is present at less than $3.00/sq’ material cost (delivered).

The HB-97.2 ESD Conductive Epoxy Primer and matching HB-97.2 ESD Urethane Top Coat meet ESD Association (ESDA) standards and is compliant with ANSI/ESD S20.20-2014 recommendations for grounded static-control flooring.  The HB-97.2 system has an electrical resistance of 1.0 x 10e5 to 5.0 x 10e5 and limits static charge generation to less than 15 volts. Recommended for use on concrete, wood and old VCT floors.  Comes in a gloss finish.  The HB-97.2 ESD Primer is moisture tolerant and can be applied to a floor <75% relative humidity.  The HB-97.2 ESD system offers easy maintenance and never requires waxing or buffing.

Available in a 3 gallon kit and 7 standard colors.  Custom coloring available on special order basis to meet your specific color matching requirements.

Recommended minimum coverage rate for HB-97.2 primer is 160 sq’/gallon (10 mils thick) for great performance up to as much as 20 mils thick in one coat for extremely heavy traffic systems. We also offer the option to include a Two-inch-wide copper grounding strip for grounding to earth grounds. Copper is 1.4 mil thickness (2.6 mil thickness with the conductive adhesive backing).  Recommend at least 1 grounding strip every 1,000 sq’ of project surface area.  See the guide:  HOW TO GROUND ESD COATINGS

MIXING AND APPLICATION INSTRUCTIONS

RODUCT 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.

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.  If the concrete has been treated or sealed, proceed with complete removal process 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. The success of industrial diamond grinding as a concrete preparation method will vary depending on technique and the hardness of the concrete

Grounding Required for the HB-97.2 Epoxy Basecoat:  We offer the option to include with the HB-97.2 Epoxy, a Two-inch-wide copper grounding strip for grounding to earth grounds. Copper is 1.4 mil thickness (2.6 mil thickness with the conductive adhesive backing).  Recommend at least 1 grounding strip every 1,000 sq’ of project surface area.  See the guide on how to properly ground your floor:  HOW TO GROUND ESD COATINGS

SCHEMATIC FOR GROUNDING AN ESD FLOOR COATING

How to Ground an ESD Floor Coating

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.

MIXING INSTRUCTIONS: Mix ratio is 2 Parts A to 1 part B by volume. A pint of coloring agent is recommended per every 3 gallon mix. The color pack should be added and mixed in homogenously prior to adding the Part B hardener. Mix all components together for 2-3 minutes with a Jiffy® ES mix blade attached to a slow speed drill. Mix only enough material at one time that can be applied without exceeding the pot life. Note: Once this material is mixed, it can’t be resealed for later use. 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 95°F (32°C). Relative Humidity (RH) should be limited to 30- 80%. DO NOT apply coatings unless the surface temperature is more than five degrees over the dew point.

SPREADING RATE:  Apply at approx. 160 sq ft/gal. When HB-97.2 ESD primer is applied, surface irregularities and porosity in the concrete may affect the coverage rate. Be sure to plan accordingly as there may be a need for extra material to provide proper coverage. Material applied too heavily may blister or can remain soft during curing. Too little material may produce dry spots and a non-uniform look. The best practice is to measure and grid the floor to be sure of proper application rate.

DRYING TIME: Unless top coating, allow HB-97.2 primer to dry for a minimum of 24 hours after application at 75°F (24°C) and 50% RH before opening the floor to light traffic, allow more time for low temperatures and higher humidity or for heavier traffic. Full coating properties may take up to 7 days to develop.

PRODUCT APPLICATION:  Apply HB-97.2 ESD primer at a rate of 10 mils (480ft² per pail) to the flooring surface using a notched or flat squeegee depending on the desired thickness. Allowing the material to sit in the pail for longer than 5 minutes will result in an increase of viscosity and reduced leveling properties. Back roll and evenly spread the wet coating using a 1/4 – 3/16 inch nap non-shed professional grade roller. Care should be taken to overlap and cross lap, but not over roll the coating introducing air to the surface. HB-97.2 ESD primer must be top coated within 24 hours (at 70-75°F, 30% RH) in order to avoid sanding. If the re-coat window has expired, the prior cured coating surface must be sanded with 100 grit sand paper or sanding screen installed on a swing-type floor buffer. Sand to a uniform dulled surface. Remove all sanding debris with a vacuum and damp mop. Scrub with detergent and rinse with clean water. Surface must be dry before coating.

CLEANUP: Clean hands and tools immediately with warm, soapy water.  Clean spills right away with a damp cloth.

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.
