Description

Carboline Carbomastic 20 is a two-component, corrosion resistant epoxy mastic for steel, offering very good protection against fresh and salt water.

Not recommended for immersion service in aromates, ketones or strong oxidizing acids. Topcoats: May be topcoated with most two-pack topcoats.

Note: Epoxies lose gloss, discolour, and eventually chalk in sunlight exposure.

Features and Benefits


  • Surface tolerant
  • Fast curing at low temperatures
  • High solids give good coverage and reduced solvent emission
  • Semi-gloss finish



Product Specification


Technical Data
Carboline Carbomastic 20
Volume Solids: 85 ± 2%
Theoretical Coverage Rate: 6,5 m²/l at 130 µm
Allow for loss in mixing and application
Dry Film Thickness: 100 - 300 microns (3.94 - 11.81 mils) per coat
Normally 130 µm
Wet Film Thickness: 120 – 350 µm per coat, normally 155 µm
Dry Temperature Resistance: Continuous: 120°C (248°F)
Non-Continuous: 150°C (302°F)
Shelf Life: 36 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) 24 Hours 30 Days
15°C (59°F) 10 Hours 20 Days
20°C (68°F) 8 Hours 10 Days
25°C (77°F) 5 Hours 10 Days



  • These times are based on 130 µm 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

  • For immersion service, blast clean to Sa 2½ (ISO 8501-1), for other service St 2-3 (ISO 8501-1) may be sufficient
  • Alternatively, ultra-high pressure water jetting to Nace No. 7 min. C Vis WJ-2. Max flash rust; C Vis WJ-2M



Application Methods

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

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. We ALWAYS recommend a trial area is coated to ensure the product meets your requirements before use.
