SHELF LIFE: One year from date of manufacture. PACKAGING OPTIONS / 3.05 gallons (11.55 litres) / 9014868 PART NUM BERS: OPTIONS: Colors in Eco-SCT. Tennant Colorants must be added to Eco-SCT. DO NOT use White. Use Light Gray, Canada Gray, Medium Gray, Summer Gray, California Gray, Sandy Beige, Baby Blue, Sky Blue, and Tile Red at a rate of 1/2 pint (8 fluid oz.) per 3.05-gallon (11.55 liter) unit of Eco-SCT. Contact Tennant Company coatings technical support if additional colorants are desired as they may not be compatible. LIMITATIONS Colors: Use of color is required in Eco-SCT. DO NOT USE White. : Hide: The topcoat must be applied over a pigmented primer or existing coating of similar color to obtain color hide in Ec o-SCT. The resulting system color w ill be closer to the primer. Contamination (Fisheyes): Product may fisheye if oil, silicones, mold release agents or other contaminants are present.

F - Fair (Moderate Adverse Effect) - Not recommended. G - Good (Limited Adverse Effect) - Use for short-term exposure only. P - Poor (Unsatisfactory) - Little or no resistance to chemical. *Only adverse effect was staining. IMPORTANT: READ AND FOLLOW ALL PRECAUTIONS AND INSTRUCTIONS BEFORE PROCEEDING. PLEASE SEE SAFETY DATA SHEET (SDS) FOR HANDLING PROCEDURES. USE PRODUCT AS DIRECTED. KEEP OUT OF THE REACH OF CHILDREN. PRELIMINARY FLOOR INSPECTIONS CHECK THE CONCRETE: Concrete must be structurally sound and free of curing membrane, paint or other sealer. If you suspect that the concrete has been previously sealed, call Tennant Company, technical support for further instructions. CHECK FOR M OISTURE: Concrete must be dry before application of this floor coating material. Concrete moisture testing must occur. In-situ relative humidity testing is recommended. Readings must be below 75% relative internal concrete humidity. Test methods can be purchased at www.astm.org, see F2170, or follow manufacturer's instructions. If moisture issues are present, the use of a moisture mitigation system may be a consideration. Please call Tennant Company Technical Support for further information / instructions. NOT E: Although moisture testing is critical, it is not a guarantee against future problems. This is especially true if there is no vapor barrier or the vapor barrier is not functioning properly and/or you suspect you may have concrete contamination. Additional testing may be necessary to determine the vapor barrier and any contamination. CHECK THE TEM PERATURE AND HUM IDITY: Floor temperature and materials should be betw een 65°F (18°C) and 90°F (32°C). Humidity must be less than 80%. DO NOT coat unless floor temperature is more than five degrees over the current, local dew point. APPLICATION EQUIPMENT • Protective clothing • Roller assembly (18") • Jiffy® mixer blade • Mohair Roller and Refill (18”) [Tennant Part No. 08643-1 (1 gal) or 08643-5 (5 gal)] • Slow speed drill (500 rpm or less) • Disc machine • 18-24" Flat rubber squeegee • 60 grit sandpaper • 18-24" 1/16" Notched rubber squeegee • 80 grit sandpaper • Spiked shoes Tennant Company, 701 North Lilac Drive, P.O.

(Clean roller w ith tape to remove any residual lint.) PREPARATION Detergent scrub and rinse w ith clean w ater to remove surface dirt, grease, oil and contaminants. One of the follow ing preparation methods may be used: EasyPrep™: With 25/35 grit concrete tool, coating system must be 10-25 mils (0.25-0.64 mm). Diamond Grinding: Coating system thickness varies w ith the type of diamond used. Sw eep and vacuum to remove fine dust. Steel Shot Blast: Coating system must be >16 mils (>0.41 mm). Use magnetic broom to remove excess shot, sw eep to remove large debris and vacuum to remove fine dust. Scarify: Coating system must be >25 mils (>0.64 mm). Sw eep to remove large debris and vacuum to remove fine dust. JOINTS: Depending on the preference of the facility ow ner, joints may or may not be filled. If the joints are filled, non-moving joints, i.e. contraction or control joints, can be hard filled w ith thickened, 100% solids epoxy or w ith a semi-rigid joint filler such as Eco-PJF™ or Ec o-EJF™. Construction joints less than one inch w ide may also be filled w ith Eco-PJF. Isolation or expansion joints must be filled w ith a flexible material designed for this purpose. APPLICATION – PRIMER ECO-SCT M UST BE APPLIED OV ER A TENNANT 100% SOLIDS EPOXY PRIMER. (See appropriate epoxy product bulletin for application instructions.) APPLICATION – BUILD COAT AT LEAST 8 M ILS OF AN EPOXY BUILD COAT ON TOP OF THE EPOXY PRIM ER ARE RECOM M ENDED FOR COM PL ET E HIDE. (See appropriate epoxy product bulletin for application instructions.) ELECTRICAL GROUNDING If Ec o-SCT is the primary ground, then a grounding system that meets the customer's specifications needs to be connected to the common ground of the facility. If copper tape is used, install the copper tape on the insulator coat, underneath the Ec o-SCT. APPLICATION – TOPCOAT – ECO-SCT COVERAGE RATE w ill depend upon required thickness.
