Description

Carboline Carboguard 690 is a high performance, surface tolerant epoxy that has excellent resistance to water and wastewater exposures. This coating exhibits outstanding moisture tolerance during application, low temperature cure capability, and fast cure response for quick return to service.

Can be used on structural steel, piping, tankage, and equipment exposed to industrial or marine environments. It can also be used in immersion service for salt water, process water (non-potable) and waste water treatment projects; and is ideal for coatings under insulation on pipes up to 300°F(150°C).

Product Specification


Technical Data
Carboline Carboguard 690
Volume Solids: 80% +/- 2%
Temperature Resistance (Immersion): Immersion temperature resistance depends upon exposure (120°F maximum). Contact Rawlins on Tech - 0113 2455450 (option 2) or [email protected] Sales - 0113 2455450 or [email protected] for specific information.
Linings exposed to cargos warmer than the outside steel temperature are subject to a "cold-wall' effect. The smaller the temperature differential, the less negative influence on performance.
Theoretical Coverage Rate: 1283 ft²/gal at 1.0 mils (31.5 m²/l at 25 microns)
257 ft²/gal at 5.0 mils (6.3 m²/l at 125 microns)
160 ft²/gal at 8.0 mils (3.9 m²/l at 200 microns)
Allow for loss in mixing and application
Dry Film Thickness: 5 - 8 mils (127 - 203 microns) per coat
Primer: Self-Priming, zinc-rich, or epoxies
Topcoats: May be coated with acrylics, epoxies, alkyds, or polyurethanes depending on exposure and need.
VOC Values: As Supplied: 1.42 lbs/gal 170 g/l mixed
Thinner 2: 16* oz/gal 2.06 lbs/gal 248 g/l
Flash Point: Part A: 91°F (33°C)
Part B: 80 °F (27°C)
Thinner 2: 23°F (-5°C)
Limitations: Epoxies lose gloss, discolour and eventually chalk in sunlight exposure. Discoloration is more pronounced with this product.
For immersion projects use only factory-made material in special colours
This product can be applied over damp or even wet substrates. Remove excess water by blowing down the surface and apply in multiple coats to achieve desired film thickness.
Brush or roller, and multiple coats are preferred over wet substrates.
Severe Exposures: Under insulation temperature resistance:
Continuous: 300°F (149°C)
Non-Continuous: 350°F (176°C)
Discoloration occurs above 200 F (93 C) but does not affect performance
Shelf Life: Part A: 24 months at 76°F (24°C)
Part B: 24 months at 76°F (24°C)
Shelf Life: (actual stated shelf life) when kept at recommended storage conditions and in original unopened containers.
Storage Temperature and Humidity: 40 -100°F (4°C-38°C)
0-95% Relative Humidity



Drying Times


Curing Schedule
Surface Temp Dry to Touch Minimum Recoat Time Maximum Recoat Time Minimum cure for immersion service
20°F (-7°C) 10 Hours 72 Hours 60 Days 45 Days
35°F (2°C) 6 Hours 17 Hours 45 Days 30 Days
60°F (16°C) 5 Hours 6 Hours 30 Days 14 Days
75°F (24°C) 4 Hours 2 Hours 15 Days 7 Days
90°F (32°C) 2 Hours 2 Hours 7 Days 6 Days



These times are based on a 5.0-8.0 mil (125-200 micron) dry film thickness per coat.

  • 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 discoloration, and may result in a surface haze. Any haze or blush must be removed by water washing before recoating.
  • If the maximum recoat times have been 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.
  • For application and cure conditions below 35°F, dehumidify before, during, and after application to prevent ice formation on the surface.



Curing Schedule
Surface Temp Dry to Handle Dry to Recoat
35°F (2°C) 48 Hours 2 Days
60°F (16°C) 24 Hours 40 Hours
75°F (24°C) 8 Hours 24 Hours
90°F (32°C) 6 Hours 24 Hours



  • The above times are based on 16 mils (400 microns) DFT of Carboguard 690 applied in a single coat. Honour the other precautions outlined above



Surface Preparation


General

  • Remove any oil or grease from surface to be coated with clean rags soaked in Carboline Thinner 2, or toluol.

Steel

  • Immersion: SSPC-SP10; Surface Profile: 1.5-3.0 mils (38-75 microns) (See Limitations).
  • Non-Immersion: SSPC-SP6; Surface Profile: 1.5-3.0 mils (38-75 microns) In certain situations hand tool or power tool cleaning (SSPC-SP2 or 3) is acceptable for thicknesses up to 8 mils (200 microns)

Concrete or CMU

  • Clean and dry
  • Remove all loose, unsound concrete
  • Do not apply coating unless concrete has cured at least 28 days @ 70°F (21°C) and 50% relative humidity or equivalent.



Application Methods


Product Information

Thin up to 12.5% by volume with Carboline Thinner 2 for non-immersion applications and Thinner 10 for immersion projects.
Pot Life: 1.5 hours at 75°F (24°C) and less at higher temperatures. Pot life ends when coating becomes too viscous to use.
Spray Application (General): Hold gun 12-14 inches from the surface and at a right angle to the surface.
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: 45:1 (min.)
Volume Output: 11.5 l/min min. (2.5gpm min.)
Material Hose: 12.5mm min. (½” I.D. recommended)
Tip Size: 0.43-0.53mm (0.017-0.021”)
Output: 140-175kg/cm²
Pressure: (2000-2500 psi)
Brush and Roller (General): Not recommended for tank lining applications except when striping welds.
For non-immersion applications over damp surfaces, brush and roller is the preferred method.
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 75°F (24°C).
Thin up to 12.5% by volume per gallon with Carboline Thinner 2. Use a short-nap synthetic roller cover with phenolic core.

  • Industry standards are for substrate temperatures to be above the dew point.
  • For immersion conditions it is recommended to follow this procedure.
  • For non-immersion conditions this product can tolerate damp substrates.
  • Special thinning and application techniques may be required above or below normal conditions.



Health and Safety


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.
  • 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.
