VOC Compliant in all 50 US States, Meets USGBC LEED Requirements

CONSIDERATIONS

Substrate must be above 50°F and relative humidity below 85% for proper curing.
Substrate must be properly prepared following Epoxy.com recommendations and free of dirt, waxes, curing agents and other foreign materials
Excessive moisture in the substrate will require a moisture vapor control treatment like Product #830
Concrete substrate must be insulated with a non-conductive epoxy primer/basecoat like Product #12 Chemical Resistant Epoxy Primer or Product #899 Epoxy Primer prior to application of Product #668 Conductive Epoxy Primer. Consult with Epoxy.com Technical Department for recommendations.
Must be topcoated with a conductive topcoating like Product #1ESD, or Product #630 Conductive.

APPLICATION

SURFACE PREPARATION

Surface Preparation is the most critical portion of any successful resinous flooring system application. All substrates must be properly prepared and tested for moisture as outlined in installation proceedures or as recommended by Epoxy.com.

BATCHING, MIXING & INSTALLATION

Product #668 Conductive Epoxy Primer:
PART A 1 quart to
PART B 3 quarts to
Clean Water 8 volume ounces (6% by volume of water)
Total 4.125 quarts

Coverage (250 square feet/gal.) 265.6 square feet per batch

Pre-mix Product #668 Conductive Epoxy Primer part B prior to combining with part A. Mix 1 part A with 3 parts B for 2-3 minutes with a low-speed jiffy mixer, scraping sides and bottom of mix vessel. Continue mixing and add 6% by volume clean potable water and continue mixing for 1 additional minute.

Immediately spread and backroll mixed Product #668 Conductive Epoxy Primer at a rate of 250 ft2 per gallon with a short nap roller over previously applied non-conductive epoxy primer/basecoat. Care should be taken to avoid puddles. Allow to cure minimum 12 hours (at 75°F) to maximum 24 hours before coating with specified topcoat.

Important: Test Product #668 Conductive Epoxy Primer with ohm meter prior to topcoating to confirm acceptable level of conductivity is achieved. If test readings are higher than 25,000 ohms, contact Epoxy.com Technical Support Department for further instructions before installing specified topcoat.

Top Coat with a conductive topcoating like Product #1ESD, or Product #630 Conductive.

CLEAN-UP

Clean skin with soap and water. Tools and equipment should be cleaned with warm soapy water, xylene or lacquer thinner. Consult Material Safety Data for safety and health precautions.

COMPOSITION

Waterborne Epoxy Resin and Conductive Filler. Color: Black.
