ADVANTAGES
- For Use with Various Epoxy.com Conductive Systems
- Maintains Electrical Conductivity Performance over the Wear Life of the System
- Fast Dry Time
- Low Odor During Application and Cure
- 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/base coat like Product #12 Chemical Resistant Epoxy Primer or Product #899 Epoxy Primer prior to application of Product #659 Conductive Epoxy Primer. Consult with Epoxy.com Technical Department for recommendations. - Must be top coated with a conductive top coating 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 procedures or as recommended by Epoxy.com.
BATCHING, MIXING & INSTALLATION
Product #659 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 #659 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 back roll mixed Product #659 Conductive Epoxy Primer at a rate of 250 ft2 per gallon with a short nap roller over previously applied non-conductive epoxy primer/base coat.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 #659 Conductive Epoxy Primer with ohm meter prior to top coating 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 top coating 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.
