DESCRIPTION AND RECOMMENDED USES: ARCOR™ S-16 is a solvent free epoxy coating designed as a protective coating for metals in immersion service. ARCOR™ S-16 produces a tough, chemical resistant, flexible coating that is ideally suited for aggressive water service(salt, brackish). Enhanced by multi functional chemistry the ARCOR™ S-16 is a fine multipurpose coating suited for moderate acid and caustic service, and is excellent in water environments. A fine general use epoxy. S-16 is; NSF Certified for Potable Water; USDA for Incidental Food Contact in Meat & Poultry Production; FDA Guideline CFR 21 Section 175.300 listed for Repeated Food Contact use.
SEE MATERIAL SAFETY DATA SHEET BEFORE HANDLING THIS PRODUCT
Steel surfaces: Always abrasive blast with chloride free abrasive. Exterior applications to SSPC SP-10 Near White metal finish. Immersion applications to SSPC SP-5 White metal. Grind flat all burrs, weld seams, radius sharp edges. Fresh blasted surfaces to be primed with ARCOR™ S-30 Prime or ARCOR™ S-16 only in NSF, USDA or FDA Applications. Concrete surfaces : Not Recommended for hand or roller application. Apply by heated plural or airless spray only. Concrete surfaces should be degreased if oil and grease contamination is present. Degreased surface shall be high pressure washed, acid etched and high pressure washed again so surface is clean and free of all grease, oils and surface laitance. Existing coatings should be abrasive blasted to clean concrete. Prime with ARCOR™ S-16 only in NSF, USDA or FDA Applications; or VICOR™ EE-70, EE-79 or VICOR™ EE-10.
Thoroughly mix Activator into Base with mixing stick or drill with low speed mixing blade. Mix by Volume 4 parts Base to 3 parts Activator. Or by Weight 100 gm Base to 68 gm Activator.
By Brush use medium to stiff bristle of sufficient quality that bristles do not pull out and stick in coating. Trim or tape to <1” nap.
Roller use good quality 1/8” nap.
Plural Spray use .023-.032 tip, 3,000-3,500 PSI, Heat to 130ºF Base, 110ºF Activator. Airless Spray Not Recommended
Conventional Spray Not Recommended
All spray equipment should employ traps to prevent water and oil from contaminating coating and screens to prevent particulate contamination.
Material: Keep between 55 to 95ºF(13 to 35ºC). Substrate : Keep between 45 to 105ºF (7 to 40ºC). The difference in temperature of the substrate and the coating should never exceed 10ºF (5ºC).
