Product Specification


Technical Data
Carboline Carbomastic 18 NT
Volume Solids: 80% ± 2%
Theoretical Coverage Rate: 6,4 m²/l at 125 µm
Allow for loss in mixing and application
Dry Film Thickness: 125 - 500 microns (4.92 - 19.68 mils) per coat
Normally 250 µm
Wet Film Thickness: 155 - 620 µm per coat, normally 320 µm
Dry Temperature Resistance: Continuous: 120°C (248°F)
Non-Continuous: 150°C (302°F)
Topcoats: Normally not topcoated
Limitations: Not recommended for immersion service in aromatic or ketone solvents and strong oxidizing acids. Epoxies discolour and eventually chalk in sunlight exposure.
Shelf Life: Maximum 24 months at 24°C
Storage Temperature and Humidity: 5° - 45°C
0 - 95% relative humidity



Drying Times


Curing Schedule
Surface Temp. Dry to Recoat Final Cure
5°C (41°F) 26 Hours 18 Days
10°C (50°F) 18 Hours 14 Days
15°C (59°F) 12 Hours 10 Days
20°C (68°F) 8 Hours 6 Days
25°C (77°F) 7 Hours 4 Days



  • These times are based on recommended DFT. Higher film thickness, insufficient ventilation or cooler temperatures will require longer cure times and could result in solvent entrapment and premature failure



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 with a 50 – 75 microns surface profile
  • Non-immersion: ISO 8501-1 St 2-3 is acceptable
  • Alternatively, ultra-high pressure water jetting to Nace No.7 min. C Vis WJ-2. Max flash rust; C Vis WJ-2M



Application Methods


Product Information
Mixing: Power mix separately, then add part B to Part A and power mix. Do not mix partial kits.
Thinning: May be thinned up to 15% with Carboline Thinner 15
Ratio: 4:1 (A to B)
Pot Life: 6 Hours at 20°C and less at higher temperatures
Airless Spray: Pump Ratio: 30:1 min
Volume Output: 3.0 gpm min
Material Hose: 3/8” I.D. min
Tip Size: 023-.027”
Output PSI: 2100-2300
Filter Size: 60 mesh
Brush and Roller: For small areas and stripe coating only. Multiple coats may be required to obtain desired appearance, recommended dry film thickness and adequate hiding
Brush: Use a medium bristle brush
Roller: Use a medium nap phenolic core roller



Application Conditions


Product Conditions
Condition Material Surface Ambient Humidity
Minimum 5°C (41°F) 5°C (41°F) 5°C (41°F) 0%
Maximum 35°C (95°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 cause flash rusting on prepared steel
  • 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 safety data sheet 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 the applicable local regulations
  • In areas where explosion hazards exist, workmen should be required to use non-ferrous tools and wear conductive and non-sparking shoes
  • Refer to the product and safety data sheet in the attachments section above for further details
