Protective & Marine Coatings General POlymers 3552W EPO-FLEX Flexible Wall Epoxy Part A GP3552W59 Series Part B GP3552B01 Hardener Revised September 23, 2014 Product Information Application APPLICATION INSTRUCTIONS 1. Premix 3552WA (resin) using a low speed drill and Jiffy blade. Mix for one minute and until uniform, exercising caution not to introduce air into the material. 2. Add 1 part 3552WA (resin) to 1 part 3552B (hardener) by volume. Mix with low speed drill and Jiffy balde for three minutes and until uniform. To insure proper system cure and performance, strictly follow mix ratio recommendations. 3552(W) is a viscous material and requires complete mixing to cross link properly, match the mix blade to the volume of material to insure a full mix and always mix for a minimum of 3 minutes. 3. 3552W may be applied via 3/8 roller taped and solvent washed, or brush. Apply at a spread rate of 160-200 sq. ft. per gallon to yield 8-10 mils WFT evenly with no runs. Coverage will vary depending upon porosity of the substrate and surface texture. Roller application will leave a stipple finish, a final backroll with a short nap (1/4 or 3/16 ) roller or foam roller will reduce but not eliminate the stipple. 4. Allow to cure overnight. NOTE: Epoxy materials may tend to blush at the surface especially in humid environments. After surface is primed and before installation of each subsequent coat, surface must be examined for blush (a whitish greasy film and/or low gloss). The blush must be completely removed prior to recoating using warm detergent water or through solvent wipe. Cleanup Clean up mixing and application equipment immediately after use. Use toluene or xylene. Observe all fire and health precautions when handling or storing solvents. Safety Refer to the MSDS sheet before use. Published technical data and instructions are subject to change without notice. Contact your Sherwin-Williams representative for additional technical data and instructions. Maintenance Occasional inspection of the installed material and spot repair can prolong system life. Shipping Destinations East of the Rocky Mountains are shipped F.O.B. Cincinnati, Ohio. Destinations West of the Rocky Mountains are shipped F.O.B. Victorville, California. For specific information relating to international shipments, contact your local sales representative. Epoxy materials will appear to be cured and dry to touch prior to full chemical cross linking. Allow epoxy to cure 2-3 days prior to exposure to water or other chemicals for best performance.
