Epoxy.com Product #2671 Conductive Primer Sealer is a two component solvent based epoxy primer that exhibits excellent characteristics for abrasion resistance and static dissipative properties. Another outstanding feature for this product is the excellent substrate penetration which results in excellent adhesion characteristics. The semi-clear is a metallic pigmented primer while the black is available in a metallic pigmented version with additional lead time.
Recommended for priming concrete or masonry substrates prior to applying a suitable topcoat when static control is needed.

Store product in an area so as to bring the material to normal room temperature before using.
Surface preparation will vary according to the type of system to be applied. For a one or two coat thin build system (3-10 mils dry) we recommend either mechanical scarification 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'x4' 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.
Mix equal volumes such as 1 gallon of part A to 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. Improper mixing may result in product failure. Suitable mixing equipment may be necessary to remix in settled metallic pigment.
The mixed material can be applied by brush or roller. Maintain temperatures within the recommended ranges during the application and curing process. The Product #2671 conductive primer is best earthed with strips of copper about 20 centimeters long, which are anchored in the subfloor and connected to a water pipe or neutral conductor in the electric wiring system. Two earthing points normally suffice for a single room. One earth per 200 square meters of floor space is the general rule for large areas. After the substrate is earthed, Apply the Product #2671 by roller or brush at the recommended (6-7 Mil) thickness. Too thick of an application may result in inefficient conductivity or solvent entrapment that could result in product failure. Allow sufficient time for the Product #2671 to cure before recoating. SEE ABOVE UNDER LIMITATIONS FOR TESTING PROCEDURES.
Recoating is optional. If you opt to recoat or topcoat this product, you must first be sure that all of the solvents have evaporated from the coating during the curing process. Always remember that colder temperatures will require more cure time for the product before topcoating. Before topcoating, check the coating to insure no epoxy blushes were developed (a whitish, greasy film or deglossing). If a blush is present, it must be removed prior to topcoating. If topcoating or applying multiple coats, apply the selected anti-static topcoat according to the technical data specifications. Be sure to apply the topcoat product at the specified coverage rate or recommended thickness. We only recommend one coat of any anti-static topcoat be applied over the conductive sealer. However, if multiple coats of this sealer are to be placed, then a re-evaluation of conductive properties should be conducted at the job sight location to determine adequate conductive properties with a representative sample first. Consult Epoxy.com Technical Support for proper anti-static topcoat selections. Adequate leakage resistance should be less than 108 ohms measured at 500 volts per ASTM F150-89 over concrete. Typical conductive properties for this product as used on concrete with one coat is typically 105 to 109 ohms PER ASTM F150-89 at 500 volts).

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.
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.
THIS PRODUCT IS NOT FOR A CONDUCTIVE COATING SYSTEM. THIS SYSTEM IS NOT INTENDED FOR AREAS EXPOSED TO EXPLOSIVE MEDIA SUCH AS AMMUNITION PLANTS. THIS MATERIAL IS PROVIDED AS A STATIC DISSIPATIVE COATING. REVIEW THE DATA ABOVE UNDER ELECTRICAL RESISTANCE FOR TESTING RESULTS. REVIEW YOUR ELECTRICAL RESISTANTCE REQUIREMENTS BEFORE INSTALLING THIS PRODUCT. DO NOT USE WAXES UNLESS THEY ARE SPECIFICALLY FORMULATED AND RECOMMENDED FOR ANTI STATIC APPLICATIONS. ALWAYS APPLY TEST PATCHES OF YOUR SELECTION TO CHECK CONDUCTIVITY PRIOR TO APPLICATION AND TO BECOME FAMILIAR WITH THE PRODUCTS APPLICATION PROCEDURE.
