Drying Times

Curing Schedule
Surface Temp Dry to Recoat Final Cure
21°C (70°F) 10 Hours 7 Days
29°C (85°F) 6 Hours 5 Days

  • Within 24 hours after coating is applied a minimum substrate temperature of 21°C (70°F) is required for proper polymerization

Curing Schedule
Surface Temp Dry to Recoat
54°C (130°F) 18 Hours
60°C (140°F) 10 Hours
66°C (150°F) 6 Hours
77°C (170°F) 3.5 Hours
88°C (190°F) 2 Hours

  • The chart above outlines the cure for service (immersion) times when the Force Cure schedule below is followed

Force Cure

  • NOTE: Temperatures listed for 130°F and above are for force cure
  • Force curing at elevated temperature will increase resistance to certain exposures. When exposure is severe, force curing is recommended to obtain maximum resistance and service life
  • Allow an air-dry time of 2-5 hours @ 21-37°C before heat curing. After air drying the substrate temperature should be raised by approximately 15°C each 30 minutes until the desired force cure temperature is reached
  • Final cure may be checked by exposing coated surface to MIBK for ten minutes. If no dissolving and only minor softening of film occurs the curing can be considered complete. The film should reharden after exposure if cured

Surface Preparation


  • Immersion Service or Aggressive Chemical Exposures (Spill/Fume)
  • Abrasive clean to an SSPC-SP10 or NACE No. 2 (Near-White metal surface)
  • Profile: 25-75 microns
  • Non-Immersion (Atmospheric)
  • Preferred: SSPC-SP6; Where abrasive blasting is not permitted or practical, clean per SSPC-SP3 to yield a rough (non-polished) surface

Galvanised Steel


  • Surface shall be clean and grease free with a blast produced anchor pattern or “tooth” as described earlier under steel. In addition, the blasted surface shall be given a chemical treatment
  • For immersion, blasting with sharp grit followed by the chemical surface treatment is required

Concrete or CMU

Application Methods

Product Information
Mixing: Mix the Part A and part C separately, then add the Part C to the Part A and mix thoroughly. The B (powder) can then be mixed slowly into the liquid. The mixture should stand approximately 30 minutes to "sweat in" before use

Thinning will be necessary to spray this coating

Thin up to 10% for normal temperatures and add up to 20% thinner for higher temperatures if necessary

Use Plasite Thinner 71 (a medium-fast thinner) for internal tank lining; and Plasite Thinner 19 (a slower thinner) for exterior (hot or windy) conditions

Pot Life: 24 hours at 21°C and less at higher temperatures
Spray Application (General):

Spray gun should provide an 8-12 inch-wide spray pattern with best possible atomization. Apply a “mist” bonding pass. Allow to dry approximately one minute but not long enough to allow film to completely dry

Apply crisscross multi-passes, moving gun at fairly rapid rate, maintaining a wet appearing film. Observe the coating surface, and when it appears to be flowing together you will have an average 150-175 microns wet film. By allowing the solvents to flash-off for a few minutes, several faster multi-passes may be applied until you have a film thickness of approximately 150-175 microns - approximately 10-12 wet mils. Repeat above procedure for second coat-obtain a film of 250-300 microns DFT

Conventional Spray:

Air pressure: 50 psi at the gun

Pot Pressure: 10-15 psi

Airless Spray:

Fluid Pressure: 1500-1800 psi

Tip Size: 0.015-0.021 inches


Recommended for small areas and repairs only. Use a high-quality brush and apply a very light crisscross brush coat. Allow to dry for approximately 5 minutes. Then apply a heavy coat using a crisscross brush pattern. “Flow” the coating on rather than try to “brush out.” Allow to dry tack free. Repeat until sufficient film thickness is obtained. Normally a film thickness of 62-75 microns can be obtained per coat by this method

Note: must be agitated frequently

Health and Safety

Clean Up

  • Use Carboline Thinner 71
  • In case of spillage, absorb and dispose of in accordance with local applicable regulations


  • Observe the precautionary notices on the container label, and read the Material Safety Data Sheet before use
  • Employ normal workmanlike safety precautions


  • When used in enclosed areas, thorough air circulation must be used during and after application until the coating is cured.
  • The ventilation system should be capable of preventing the solvent vapor concentration from reaching the lower explosion limit for the solvents used
  • User should test and monitor exposure levels to ensure all personnel are below guidelines
  • If not sure or if not able to monitor levels, use MSHA/NIOSH approved supplied air respirator


  • Fire and explosion hazards: This product contains less than 1% volatile components, however, vapours are heavier than air and can travel long distances, ignite and flash back
  • Eliminate all Ignitions sources. Keep away from sparks and open flames
  • All electrical equipment and installations should be made and grounded in accordance with applicable local regulations
  • In areas where explosion hazards exist, workers should be required to use non-ferrous tools and wear conductive and non-sparking shoes
  • Refer to the product data sheet and safety data sheets in the attachments section above for further details
