DESCO INDUSTRIES INC TECHNICAL BULLETIN TB-7001 Statguard® Conductive Acrylic Paint Application Instructions PMS 432 PMS 429 Figure 1. Statguard® Conductive Acrylic paint. Test Patch Requirement A test patch on new applications is required to receive a full product warranty. Prior to the shipment of your Statguard® Conductive Acrylic Paint, Desco Industries Inc (DII) will provide samples and technical documentation for installing the test patch. The test patch will allow for a full evaluation of the floor preparation and of our Statguard® Conductive Acrylic Paint, performance features to include color, adhesion, physical properties and electrical resistance. Test Patch application instructions are located in the Surface Preparation section. Please contact your customer service representative to organize a test patch kit. Made in the United States of America Allow newly applied paint to dry a minimum of 48 hours before proceeding with the test. At humidity levels over 55% RH, allow 72 hours of drying time before testing. Use a razor to cut a cross or a few perpendicular lines over a 3” by 3” (75 mm by 75 mm) area on several spots of the thoroughly dried area. (See Figure 2). Use a piece of masking tape to cover the marked area. Make sure the tape is thoroughly adhered to the test area. Pull the tape off the surface and examine the amount of paint which has peeled off during the test. If any significant portion is transferred to the tape, better surface preparation (acid etching, cleaning or sanding) should be done on the substrate to enhance the adhesion. If your test patch is on a bare or prepped concrete we recommend Bulls Eye® Water-Base Primer and Sealer to achieve proper performance of the Statguard® Conductive Acrylic Paint properties. Please contact Rust-Oleum for additional product details. Description Statguard® Conductive Acrylic Paint is a one part floor coating formulated to produce controlled dissipation of static electrical charges. Statguard® Conductive Acrylic Paint is very effective as a static control floor coating for electronics manufacturing, assembly, and storage. It is available in grey (similar to PMS 432) in 5 gallon (19 liters) containers; and in light grey (similar to PMS 429) in 5 gallon (19 liters) containers. The color may vary between production lots. NOTE: Statguard® Conductive Acrylic Paint should not be allowed to freeze. Store at temperatures above 34°F (1°C) as stated in the Safety Data Sheet. We recommend that these products be stored in their original containers and be sealed when not in use. We cannot guarantee performance if not properly mixed or used within 3 months from date of sale. Surface Preparation 1. Use a razor to cut into a painted, dried floor. 2. Apply tape on the precut area. 3. Pull the tape off. 4. Examine the degree of paint separation from the concrete. The two most important characteristics for successful application of Statguard® Conductive Acrylic Paint applications are: 1. The surface must be clean, dry, dull, and smooth. Heavy dirt or grease build-up should be removed with a stripper or degreaser. Cleaning methods range from: sweeping, vacuuming, wire brush, air-blasting, water jet, steam cleaning, or stripping. 2. If the surface is concrete, it must be in good condition. Figure 2. Adhesion test on the painted floor.

Not all concrete is created equal -- concrete surfaces vary widely in physical and chemical qualities due to the way the concrete was formulated, poured, or finished. UNPAINTED SURFACES: Adhesion can be improved by using a standard industrial type primer. Metal should be primed with red oxide primer. Concrete, wood, plastics, and most other surfaces should be properly cleaned. Let dry and then apply Statguard® Conductive Acrylic Paint. There are several methods to prepare problem concrete. Each method depends on the condition of the concrete. Adhesion properties can be increased by profiling or roughing the surface through acid etching, rotary drum sanding, scarifying, or mechanically scratching the surface. COVERAGE: Statguard® Conductive Acrylic Paint will cover 300 to 400 square feet (27.87 to 37.16 square meters) at a 1 to 1.5 mil (0.0254 to 0.0381 mm) thick dry film per gallon (3.87 liters) on a smooth surface. Coverage is less on coarse or textured surfaces. Two coats are recommended to achieve maximum performance from the paint. You must test for moisture in the concrete. If moisture is present, the floor should not be coated until the source of the moisture is determined and eliminated. Limitations Below criteria is generally accepted for concrete and other porous substrates: • Do not install when the moisture vapor emission rate (MVER) exceeds 6lbs. per 1,000 sq. ft. (2.72 kg per 92.9 m2) per 24 hours, Measure the MVTR of the concrete prior to tile installation, using the industrial standard test probes per ASTM F2170.Do not install with relative humidity of concrete slabs exceeds 75% (ASTM F2170) • Use only when the substrate temperature is between 65°F and 85°F (18°C and 29°C) Warning: Moisture levels greater than above mentioned may negatively affect the drying/curing process, bond strength to substrate, as well as hardness of the finished film. PRIMING: Statguard® Conductive Acrylic Paint bonds well to primed/sealed clean, dry concrete. However if the sub floor is bare or prepped concrete we recommend using the Bulls Eye® Water-Base Primer and Sealer to achieve proper performance of the Statguard® Conductive Acrylic Paint properties. Please contact Rust-Oleum for additional product details. Installing Statguard Conductive Acrylic Paint on improperly prepared surfaces will void product warranty and cause product failure. ® PREVIOUSLY PAINTED SURFACES: The surface should be clean and free of dust, grease, wax, and soap residue. Wash with ordinary detergent and water. Rinse thoroughly with clean water and let dry. Glossy surfaces can be dulled by lightly sanding and then vacuuming and cleaning. Cracks and holes should be repaired before applying the Statguard® Conductive Acrylic Paint. Adhesion can be improved by using a standard industrial type primer. Application Always use in a well ventilated area or wear a suitable respirator. Wear appropriate eye protection such as splash goggles and impervious type protection gloves to protect hands. MIXING 1. Mix paint thoroughly before use (See Figure 3) using a 500-1500 RPM variable speed drill and paint mixing attachment or a paint mixer. 2. If the paint, after properly mixing, is not freely transferring from the roller to the floor, the Statguard® ESD paint can be thinned with water up to 10% max by volume. a. Start by slowly mixing 5% water into the master container and apply again. b. Do not add more than 10% of water to the mix. 1. Mix any settled solids to 2.

Stir paint thoroughly to mix any settled solids to produce uniform grey color. 2. Combine separate cans of paint into one container to ensure uniform color distribution. It is recommended that a test area be coated to ensure that the adhesion and electrical performance of the paint is acceptable. (See Adhesion Testing, Figure 2.) If the test areas show inadequate adhesion, use an industrial floor primer/sealer. 3. Saturate a 1/4” (6.35 mm) fine nap roller or an industrial brush with paint. Remove excess paint and trapped air from the applicator by moving applicator several times in the paint tray. 4. A minimum number of strokes from the applicator on the substrate is recommended to minimize air bubbles. APPLICATION BY SPRAY Conventional Spray Gun: “E” fluid tip and needle and #704, 765 or 78 air gap. Airless Spray: Spray gun and spray cap or suitable orifice diameter 0.020-0.025” (0.508-0.635 mm). Mix paint thoroughly before using and stir occasionally when applying. No thinning necessary for Figure 4. Spray paint spray applications. Room temperature must be above application. 50°F (10°C). A minimum of two coats of Statguard® Conductive Acrylic Paint is recommended for appropriate static protection. Grounding Conventional grounding practices like connecting coated surfaces to equipment or earth ground is recommended for meeting ANSI/ESD S20.20, EN 61340-5-1 and ISO 9000 recommendations for verifying grounds. However the following is also true of conductive Acrylic Paint flooring “Floor finishes … function by two separate mechanisms. First, they reduce the surface’s tendency to generate a static charge. Second, they provide a path for the dissipation of charge. The charge may dissipate over the surface of the finish or it may dissipate to ground if the floor finish is grounded.” [Per ESD Handbook ESD TR20.20 section 5.3.4.2] Figure 5. ESD Floor Ground Strip. Four examples on how to achieve connection to the Conductive Acrylic Paint surface are: 1. Install a Statguard® ESD Floor Ground Strip per 1,000 square feet throughout the installation. 2. Bring Conductive Acrylic Paint coating in contact with a building ground rod. 3. Install a grounded lag bolt to the floor so the bolt comes in contact with the Conductive Acrylic Paint when screwed in place. 4. Bolt a grounded metal plate to the Conductive Acrylic Paint surface. Statguard® Conductive Acrylic Paint applied in excess of 50 square feet (4.6 square meters) enable the surface to dissipate 5000 volts to zero in less than 0.01 seconds per FTMS 101C, Method 4046 without conventional grounding grids or wires. The conductive coating becomes a capacitive reservoir that effectively drains static charges. ESD footwear must be used in conjunction with Statguard® Conductive Acrylic Paint to ground personnel. If footwear/flooring is being used as a primary ground to meet the personnel grounding requirements of ANSI/ESD S20.20 then we would advise to ground the Conductive Acrylic Paint for testing and verification of a ground point. If the footwear/flooring are being used as a secondary or back up grounding for personnel then grounding practices like electrically connecting Statguard® Dissipative Floor Finish to ground is only required for applications of Conductive Acrylic Paint that are less than 50 square feet. For applications that are greater than 50 square feet, the capacitance of Conductive Acrylic Paint is several hundred times greater than the capacitance of the human body model at 100pF. The difference in capacitance is so great that the Statguard® treated floor acts as a second capacitor in series with the person and a human body charge even as great as 5,000 volts will have a resulting voltage well below the 100V limit peak of ANSI/ESD S20.20. The surface resistance of the Statguard® treated floor will decay a 5000v charge to zero in .05 sec. per FTMS 101B, Method 4046. Statguard® has substantially less than the maximum static decay time of 0.1 seconds.

Remove paint spills promptly with a wet cloth. Close container after each use. Keep container from freezing. Type Water base acrylic coating Color Grey, Light Grey Finish/Sealer Statguard® Conductive Acrylic Paint can be overcoated or sealed with Statguard® Floor Finish static dissipative coating to increase durability, enhance shine, improve ease of maintenance, and seal out dirt and debris. Because of the matte finish of Statguard® Conductive Light Grey Acrylic Paint it is recommended that Statguard® Floor Finish be applied for gloss and ease of maintenance. Statguard® Dissipative Floor Finish is a polymer base floor finish/sealer that can be used as a top coat on the Conductive Acrylic Paint. Surface Resistance will then be in the 1 x 105 to < 1 x 108 ohm range. Two coats are recommended. Three coats will improve electrical properties, durability and reduce frequency of maintenance. Apply Statguard® Floor Finish after 48-72 hours after last coat of paint. Paint becomes dry to the touch, but is not fully cured to accept a finish coat until this time. If you notice the paint color coming off when finishing,it is too soon to apply. Please wait for the paint to cure fully. Ask for Technical Bulletin TB-7042 for more information on Statguard® Floor Finish. Maintenance Use sweeper, vacuum, or broom to remove dirt. Allow two weeks drying time before using a damp mop to clean the coated area. Do not use abrasive cleaners, floor rinse, or scrubbing machine to clean the floor.

To best ensure consistent results, the test should be done at various locations. ELECTRICAL PROPERTIES: Test the surface, point-to-point resistance, (Rtt) and resistance-to-ground (Rtg) properties of coated area per ANSI/ESD STM7.1 test method and/or ESD TR53. For quick and easy verification of the paint’s electrical properties, we recommend the use of our a Surface Resistance Test Kit (Figure 6).
