High performance topcoat for use over 45 - 2K Red Epoxy Primer for protection of exterior storage tanks.
- Application
Surface Preparation: Newly primed surface should be clean and dry. Previously painted surfaces should have all loose paint removed and edges feathered. Prime bare spots with 45R - l 2K Red Epoxy Primer.
Activation: Thoroughly mix 6 parts 55W-J White HP Polyurethane with 1 part of 95C-F063 Activator. Mix each component
Reduction: No reduction required.
Potlife: 3 hours @ 77 °F. (Activated)
Equipment: Mix by hand or 2 component proportion pump
Cure time- hours: 77°F @ 50% RH - 3 mil drawdown.
Dry to Touch: 4 hrs.
Dry to Recoat: 4 hrs.
Dry to Handle: 8 hrs.
Pack / Ship: 24 hrs.
Full Cure: 7 Days
*Temperature, relative humidity, and film thickness will affect dry time.Suggested Film Build:
6 mils (150 µm) wet
3 mils (75 µm) dryWash Thinner: Ketones are most effective. Do not use aliphatics or alcohols.
Equipment: Spray application:
- 2001 BINKS
- Fluid Nozzle- 63CSS
- Air Cap- 63PR
- Others may be used. Changes in pressure and tip size may be required.
Roll & Brush: ¼ - ½ inch Nap Roller cover. Keep roller wet. Roll in one direction, rewet, then cross roll.
Brush apply with china bristle brush. Do not cross brush to reduce lap marks.Clean Up: After shutdown or before a long delay, Prompt Clean Up Of All Equipment Is Essential, If Equipment Damage Is To Be Avoided. This applies to pots, lines, hoses and guns. Use MEK, Acetone, or Xylene wash thinners

Technical Details & Test Data
- Compatibility with Other Coatings
Aexcel high solids polyurethane is compatible with most coating types in good condition. Testing should be performed to assure adhesion and compatibility in an inconspicuous place before work begins.

All polyurethane systems, whether single or multi-component, are sensitive to moisture and will gel or begin to cure if permitted to come into contact with humid air or water. This includes the exposure of the coating in open containers or contact with moisture in fluid and air lines. Air compressors should be equipped with moisture traps, driers, and filters to ensure that the coating does not "see" moist air. In this way, damage to equipment can be avoided.
Safety & Health
- Precautions
Safe Handling: When this product has been combined with our urethane curing agent, aliphatic and/or aromatic polyisocyanates then are present, which give off harmful vapors of isocyanates (hazardous materials) when sprayed. Do not use if you have chronic (long-term) lung or breathing problems, or if you have ever had a reaction to isocyanates. Use only with adequate ventilation. Where overspray is present, a positive-pressure, airsupplied respirator (TC-19C NIOSH/MESA) is recommended. If not available, use a vapor/particulate respirator that respirator supplier recommends as effective for isocyanate vapors and mists, such as a NIOSH TC-23C type. Refer to our Data Sheet "Safety in the Handling and Use of Uthanes," and to the Material Safety Data Sheet, available upon request.
First Aid: If affected by inhalation of vapor or spray mist, remove to fresh air. If breathing difficulty persists or occurs later, consult a physician and have label information available. In case of eye contact, flush immediately with plenty of water for 15 minutes; call a physician. In case of skin contact, wash thoroughly with soap and water.
