Drying Times


Curing Schedule
Surface Temp Dry to Recoat Final Cure Immersion Maximum Recoat Time
0°C (32°F) 24 Hours 10 Days 60 Days
10°C (50°F) 12 Hours 7 Days 30 Days
20°C (68°F) 6 Hours 5 Days 30 Days
30°C (86°F) 2 Hours 3 Days 15 Days



  • These times are based on 150 - 200 microns 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.
  • 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.
  • Note: 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: Medium to coarse in accordance with ISO 8503-2

Concrete or CMU

  • Concrete must be cured at 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
Ratio: 1:1 Ratio by Volume (Part A to Part B)
Thinning: Up to 10% with Thinner 2
Use of thinners other than those supplied or recommended by Carboline may adversely affect product performance and void product warranty, whether expressed or implied.
Pot Life: Material begins to lose film build in 90 minutes at 24°C, and less at higher temperatures.
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 a solvent resistant core.



Application Conditions


Product Conditions
Condition Material Surface Ambient Humidity
Minimum 10°C (50°F) 0°C (32°F) 0°C (32°F) 0%
Maximum 32°C (90°F) 50°C (122°F) 40°C (104°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.

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.
  • 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.

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.

It is your responsibility to read the Product Data Sheets (available below) before you place an order and prior to application of the product. The content of this website is our best recommendation and is not advice. Coverage rates quoted are approximate, you agree that coverage depends on the condition of the substrate, surface absorption, texture and application method.
