Anti-Static Conductive Primer

PRODUCT SPECIFICATIONS:

PRODUCT DESCRIPTION: The HJ-144 metallic pigmented primer was specifically developed as a base coat for the HJ-124 urethane. When used in conjunction with the HJ-124 urethane topcoat provides excellent abrasion and chemical resistance, weathering, UV stability and static dissipative properties. The electro-conductive powders used will not wear off and retain their conductive properties regardless of temperature, and perform well at all humidity levels.
RECOMMENDED FOR: Computer rooms, laboratories, aircraft hangers, chemical plants, solvent storage areas & chemical areas with regard to concrete, cement, brick, masonry or metal.

LIMITATIONS:
Colors may be affected by high humidity, chemicals, temperatures or exposure to certain types of lighting such as sodium vapor lights.
For best results use a good quality roller.
Slab on grade requires moisture barrier.
Substrate temperature must be 50 F above dew point.
All new concrete must be cured for at least 30 days.
Product color will vary from batch to batch.
Too thick of an application may result in product failure.
Do not topcoat the primer until the electrical resistance is 106 ohms of resistance or lower. In some instances, it will require 24 hours to achieve proper conductivity before topcoating. (test before topcoating).
This product is intended for the professional installer that has      experience with this type of coating system.

MIXING AND APPLICATION INSTRUCTIONS(HJ-144)
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 MATIAL IS PROVIDED AS A STATIC DISSIPATIVE COATING. REVIEW THE DATA ON THE FRONT SIDE OF THIS TECHNICAL DATA UND 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.
1) PRODUCT STORAGE:Store product in an area so as to bring the material to normal room temperature before using.
2) SURFACE PREPARATION:Surface preparation will vary according to the type of complete 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.
3) PRODUCT MIXING:(HJ-144) Mix one part A to one part B by volume. 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.
4) PRODUCT APPLICATION:This product is intended for the professional applicator with knowledge of this type of product. The mixed material can be applied by brush or roller. Maintain temperatures within the recommended ranges during the application and curing processs. The HJ-144 conductive primer is best earthed with strips of copper about 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 0 square meters of floor space is the general rule for large areas. After the substrate is earthed, Apply the HJ-144 by roller or brush at the recommended (5-7 Mil) thickness. Too thick of an application may result in insufficient conductivity or solvent entrapment and subsequent product failure. Allow sufficient time for the HJ-144 to cure. SEE FRONT SIDE UND LIMITATIONS FOR TESTING PROCEDURES.
5) RECOAT OR TOPCOATING: This product was desiigned to be topcoated with our HJ-141 Anti-Static urethane. When you topcoat this primer, 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 primer before recoating or topcoating can commence. 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. To topcoat with the HJ-141 thoroughly mix part A and part B together for the HJ-124 anti-static topcoat using slow speed mixing equipment. Apply the HJ-124 anti-static topcoat by roller or brush. Be sure to apply the topcoat product at the specified coverage rate or recommended thickness. Too thick of an application may result in product failure. We only recommend one coat of any anti-static topcoat be applied over the conductive primer.. Adequate leakage resistance should be less than 108 ohms measured at 100 to 1000 volts. Typical conductive properties for the HJ-141 system (when applied in conjuction with HJ-144 primer) follows: (HJ-124 = 105 to 107 ohms).
6) CLEANUP: Use xylol
7) FLOOR CLEANING: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.
8) 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.
