SUGGESTED USES: Prevention of rust & corrosion
VEHICLE TYPE: Epoxy Resin
SOLVENT TYPE: High Flash Naphtha, Xylene
VOC: 330 grams / liter
SOLIDS BY WEIGHT: 50%
WEIGHT PER GALLON: 11 lbs. per gallon
RECOMMENDED DRY FILM: 10.0 mils
COVERAGE: Theoretical coverage at two mils dry is 400 square feet per gallon, and recommended thickness of 10 mils dry would require 4-5 full coats. Material losses during mixing and application will vary and must be taken into consideration.
VISCOSITY AT 75°F (24°C): 70-80 KU
AVERAGE DRY TIME 75°F: Dries to touch in 2 hours. Can re-coat in 3 hours to 2 weeks. Allow 5 hours minimum to 7 hours maximum when overcoating with antifouling. If recoat window is missed, sand with 80 grit sandpaper and recoat.
RECOMMENDED REDUCER: Reduce with 974 Reducer as needed for proper flow and performance, 10% maximum.
RECOMMENDED CLEAN UP: 974 Reducer
RECOMMENDED FINISH: Ablative or Epoxy Hard antifoulings
BARE FIBERGLASS: Degrease by wiping with a rag soaked in 973 Dewaxer. Sand with 80 grade (grit) paper. Remove sanding residue. Wipe with 973 Dewaxer. Over Coal Tar Epoxy: Wash with soap and water. Rinse with fresh water and allow to dry. Sand with 80 grade (grit) paper. Remove sanding residue. Wipe with 973 Dewaxer.
BARE METAL: Surface should be blasted to bright metal. Remove all blast or sanding residue using a clean air line and sweeping with a clean brush or broom. Vacuum clean for best results. Apply primer within 1 hour of metal preparation. If blasting is not possible (or if more than 2 hours has passed since blasting) sand or grind with coarse emery cloth and apply 973 Dewaxer prior to Coal Tar Epoxy.
APPLICATION: Apply enough Coal Tar Epoxy reach a final Dry Film Thickness of 10 mils. This usually takes 1-3 coats but the amount of paint is more important than the number of coats. Airless Spray Pressure: 165 bar/2400 psi Tip Size: 0.44-0.53 mm/17-21 thou. Conventional Spray Pressure Pot: Pressure: 3.44-4.47 bar/50-65 psi (gun pressure); 10-15 psi (pot pressure). Tip Size: 1.5-1.8 mm/60-70 thou. Siphon Cup: Pressure: 3.44-4.47 bar/50-65 psi - gun pressure. Tip Size: 1.8-2.2 mm/70-85 thou. Brush Use a natural bristle brush. Roller Use a 3/8' - 1/2' nap solvent resistant roller.
POT LIFE: 5 hours
