Drying Times


Curing Schedule
Surface Temp Dry to Recoat Dry to Topcoat with Other Finishes Final Cure Immersion Maximum Recoat Time
10°C (50°F) 12 Hours 24 Hours NR 60 Days
16°C (61°F) 8 Hours 16 Hours 10 Days 30 Days
24°C (75°F) 4 Hours 8 Hours 5 Days 30 Days
32°C (90°F) 2 Hours 4 Hours 3 Days 15 Days



  • These times are based on a 100-150 micron dry film thickness.
  • Higher film thickness, insufficient ventilation or cooler temperatures will require longer cure times and could result in solvent entrapment and premature failure.
  • Excessive humidity or condensation on the surface during curing can interfere with the cure, can cause discolouration and may result in a surface haze. Any haze or blush must be removed by water washing before recoating.
  • If the maximum recoat time is exceeded, the surface must be abraded by sweep blasting or sanding prior to the application of additional coats.
  • For force curing, contact Rawlins on Tech - 0113 2455450 (option 2) or [email protected] Sales - 0113 2455450 or [email protected] for specific requirements.
  • Final cure temperatures below 16°C are not recommended for tank linings.



Surface Preparation


General

  • Surfaces must be clean and dry.
  • Employ adequate methods to remove dirt, dust, oil, and all other contaminants that could interfere with adhesion of the coating.

Steel

  • Immersion: ISO 8501-1 Sa 2½
  • Non-Immersion: ISO 8501-1 Sa 2
  • Surface Profile: 40-75 microns

Concrete or CMU

  • Immersion: Concrete must be cured 28 days at 24°C and 50% relative humidity or equivalent.
  • Prepare surfaces in accordance with ASTM D4258 Surface Cleaning of Concrete and ASTM D4259 Abrading Concrete.
  • Voids in concrete may require surfacing.



Application Methods


Product Information
Mixing: Power mix separately, then combine and power mix. DO NOT MIX PARTIAL KITS.
Thinning: Spray: Up to 6% with Thinner 2 (NSF Std.61 approved)
Brush: Up to 13% with Thinner 33 (Non-NSF Std.61)
Roller: Up to 13% with Thinner 33 (Non-NSF Std.61)
Use of thinners other than those supplied or recommended by Carboline may adversely affect product performance and void product warranty, whether expressed or implied.
Ratio: 1:1 Ratio (A to B)
Pot Life: Material begins to lose film build in 90 minutes at 24°C, and less at higher temperatures.
Spray Application (General) This is a high solids coating and may require adjustments in spray techniques. Wet film thickness is easily and quickly achieved.
Conventional Spray Pressure pot equipped with dual regulators, 3/8” I.D. minimum material hose, .070” I.D. fluid tip and appropriate air cap.
Airless Spray: Pump Ratio: 30:1 (min.)
GPM Output: 3.0 (min)
Material Hose: 3/8” I.D. (min)
Tip Size: 0.017”-0.021”
Output PSI: 2100-2300
Filter Size: 60 mesh
Brush and Roller (General): Not recommended for tank lining applications except when striping welds. Multiple coats may be required to obtain desired appearance, recommended dry film thickness and adequate hiding. Avoid excessive re-brushing or re-rolling. For best results, tie-in within 10 minutes at 24°C.
Brush: Use a medium bristle brush
Roller: Use a short-nap synthetic roller cover with phenolic core



Application Conditions


Product Conditions
Condition Material Surface Ambient Humidity
Minimum 10°C (50°F) 10°C (50°F) 10°C (50°F) 0%
Maximum 32°C (90°F) 52°C (126°F) 43°C (109°F) 85%



  • Industry standards are for substrate temperatures to be 3°C above the dew point.
  • Condensation due to substrate temperatures below the dew point can interfere with proper adhesion to the substrate.
  • Special application techniques may be required above or below normal application conditions.



Health and Safety


Clean Up

  • Use Thinner 2 or Acetone
  • In case of spillage, absorb and dispose of in accordance with local applicable regulations.

Safety

  • Read and follow all caution statements on this product data sheet and on the SDS for this product.
  • Employ normal workmanlike safety precautions.
  • Hypersensitive persons should wear protective clothing, gloves and use protective cream on face, hands, and all exposed areas.

Ventilation

  • When used as a tank lining or 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.

Caution

  • This product contains flammable solvents.
  • Keep away from sparks and open flames.
  • All electrical equipment and installations should be made and grounded in accordance with applicable regulations
  • In areas where explosion hazards exist, workmen should be required to use nonferrous tools and wear conductive and non-sparking shoes.
  • Refer to the product and safety data sheet in the attachments section above for further details.
