GENERIC TYPE: AMINE CURED 100% SOLIDS EPOXY TOPCOAT

DESCRIPTION AND RECOMMENDED USES: 8518 is a solvent free, ceramic filled high functionality epoxy Novolac coating suitable for immersion and non-immersion service, particularly in aggressive acid and alkali environments with elevated temperatures and/or abrasion. 8518 produces a tough, chemical resistant coating on ferrous and non-ferrous metals and concrete. Use of Reactive Flexibility agents gives excellent flexibility without sacrificing chemical & temperature resistance making 8518 ideal for large tank walls & floors without needing fiberglass mat. As a low viscosity epoxy Novolac 8518 is suitable for hand or spray application at up to 80 mils per coat.

APPLICATION SHEET

REVISED 4/2013

SEE MATERIAL SAFETY DATA SHEET BEFORE HANDLING THIS PRODUCT

SURFACE PREPARATION: Steel surfaces are to be abrasive blasted with chloride free abrasive. Exterior applications to SSPC SP-10 Near White metal finish. Immersion applications to SSPC SP-5 White metal 3 to 5 mil profile. Grind flat all burrs, weld seams, radius sharp edges.

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.

MIXING: Thoroughly mix Activator into Base with mixing stick or drill with low speed mixing blade scraping sides and bottom of container or mixing board. Mix by Volume 1 parts Base to 1 part Activator. Or by weight 100 grams base to 116 grams activator. Mix thoroughly to produce an even colored and streak-free material.

THINNING: Never thin.

APPLICATION: All spray equipment should employ traps to prevent water and oil from contaminating coating and 30 mesh screens to prevent particulate contamination.

Brush: medium to stiff bristle of sufficient quality that bristles do not pull out and stick in coating. Trim or tape to <1” nap. Roller:  good quality 1/8” nap.

Plural Spray: .029-.035 tip, 3,500-4,500 PSI, Heat to 150ºF Base, 100ºF Activator. Use 30 mesh screens. Heated hose @ 120-140ºF. Airless Spray: .029-.035 tip, 4,000-4,500 PSI(45:1). Use only with in-line heater at 120º to 140ºF. (Caution: Short Pot-Life) Conventional Spray:  Not Recommended.

APPLICATION TEMPERATURE: Material: Keep between 55 to 95ºF(17 to 35ºC). Substrate: Keep between 45 to 105ºF(7 to 40ºC). The difference in temperature of the substrate and the material should never exceed 10ºF(5ºC). Substrate shall be a minimum of 5ºF(3ºC) above dew point. Do not apply if relative humidity exceeds 90%. If necessary heat metal prior to surface preparation using electric heater or heat lamp. Never use gas, oil or kerosene heaters as they will leave a greasy residue on metal surface. For best results keep all material in warm area overnight(75ºF+, 24ºC) for ease of mixing. If necessary base component of material can be heated by microwave for 30-45 seconds for a 1 KG Base unit or by warm water bath. Heat activator by warm water bath only. If necessary let material cool before application.

OVERCOAT/CURE TIME: By brush, roller or squeegee re-coat while material is still soft, but tack-free, between 6-14 hours at 77ºF(25ºC). If overcoat window is exceeded abrade surface with course sandpaper, grinder or brush blast. By spray application re-coat between 2-14 hours at 77ºF. Full cure before immersion 72 hours at 77ºF. Add 30 hours additional cure time for each 10ºF below 77ºF. Subtract 12 hours of cure time for each 10ºF above 77ºF. Force Cure with heat for best performance for 4 hours at 200ºF(93ºC), 12 hours at 150ºF( 66ºC).

CLEAN UP: Clean tools immediately after use with M.E.K., Acetone, 98+% Isopropyl Alcohol or similar

WARNING: Base contains epoxy resin. Activator contains alkaline amines, a strong sensitizer. May cause skin irritation, sensitization or other allergic responses. Use with good ventilation, particularly if heated or sprayed. Prevent all contact with skin or eyes. Wear protective clothing, goggles, gloves or barrier creams. Keep containers closed when not in use. Wash thoroughly after handling. In case of skin contact immediately wash with soap and water. In case of eye contact, flush with water for 15 minutes. If irritation persists seek medical attention. Consult the Product Safety Data Sheets (SDS) BEFORE USE!
