Description

Carboline Carboguard 635 is an all-purpose immersion-grade epoxy that has a variety of attributes including low-temperature cure, surface tolerance, fast recoat times, moisture tolerance during application and cure, and excellent corrosion protection. Can be used direct to metal as a corrosion resistant primer or as an intermediate coating over other primers. Suitable for both maintenance and new construction projects due to its excellent surface wetting characteristics and quick cure for handling. May also be used for immersion in potable water, fresh or salt water (marine) exposures.

Please Note: The colour shades available are an approximation only. Due to the nature of this Carboline product, it is not possible to show an exact shade match, as each batch is made different.

Drying Times


Curing Schedule
Surface Temp Dry to Touch Dry to Handle Dry to Topcoat Minimum Dry to Topcoat Maximum
-7°C 4 Hours 36 Hours 24 Hours 180 Days
2°C 2 Hours 16 Hours 2 Hours 180 Days
10°C 1 Hour 10 Hours 1 Hour 180 Days
24°C 30 Minutes 3 Hours 45 Minutes 180 Days
32°C 15 Minutes 30 Minutes 30 Minutes 180 Days



These times are to be used as a guideline.

  • The listed times in the chart above are based on a 100-150 micron dry film thickness per coat. Deviation from those thicknesses may compromise the performance and adhesive properties of the film. Higher film thickness, insufficient ventilation or cooler temperatures could result in solvent entrapment and premature failure
  • Excessive humidity or condensation on the surface during curing will not affect performance but may cause discoloration and result in a surface haze. Any haze or blush must be removed by water washing before recoating
  • Recoat intervals may vary from those listed above when using under intumescent fireproofing products
  • Contact Rawlins on Tech - 0113 2455450 (option 2) or [email protected] Sales - 0113 2455450 or [email protected] for recommended cure times before applying Carboline intumescent products
  • 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 for specific requirements
  • Do not apply to substrates with ice or ice crystal formation
  • Dehumidify or raise the temperature to eliminate ice on the substrate
  • This product will tolerate drops in temperature to -17°C during its cure and will continue to cure when the temperature rises

Marine Use

  • Undocking time of 24 hours @23°C
  • The optimum time to topcoat with an antifoulant is when the 635 is "touch-tacky." If the touch-tacky time has been exceeded, or if the film is "glossy," you can generally re-prime/refresh the first coat of 635 with a fresh coat of itself within 30 days. The longer the first coat has to cure, particularly in sunlight exposure or elevated temps, the higher risk of inadequate adhesion. If maximum recoat times have been exceeded, the surface must be abraded by sweep blasting or sanding prior to the application of additional coats.

Maximum Topcoat Time for Atmospheric Use: 180 days

Cure for Potable Water Use: 7-day cure after final coat @23°C



Curing Schedule
Surface Temp Dry to Topcoat Minimum Dry to Topcoat with Antifoulant Maximum Dry to Topcoat with Itself
-7°C 24 Hours 36 Hours 30 Days
2°C 2 Hours 16 Hours 30 Days
10°C 1 Hour 8 Hours 30 Days
24°C 45 Minutes 4 Hours 30 Days
32°C 30 Minutes 3 Hours 30 Days



The curing schedule above references curing times for immersion service when an antifoulant topcoat is used.

  • The optimum time to topcoat with an antifoulant is when the film is "touch-tacky." If the touch-tacky time has been exceeded, or if the film is "glossy," you can generally re-prime/refresh the first coat with a fresh coat of itself. High temps and/or sunlight exposure may shorten this recoat schedule.

Marine Use

  • Undocking time of 24 hours @23°C



Surface Preparation


General

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

Steel

  • Atmospheric Exposure: For optimal performance: Hand Tool or Power Tool clean in accordance with SSPC-SP 2, SSPC-SP 3, or SSPC-SP11 to produce a rust-scale free surface. For maximum performance: SSPC-SP 6 (or greater) with a 40-75 micron blast profile
  • Immersion Service: Minimum near white metal cleanliness in accordance with SSPC-SP10
  • When using under fireproofing products, defer to the primer surface preparation requirements in the product data sheet of the fireproofing product

Galvanised Steel

  • Galvanising requires a roughened surface for optimum adhesion/performance of high build epoxies
  • Remove any contaminants per SSPC-SP1; ensure there are no chemical treatments that may interfere with adhesion; and abrade the surface to establish a suitable roughness (typically 1 mil). SSPC-SP16 or SSPC-SP7 are acceptable methods

Concrete or CMU

  • Remove all loose, unsound concrete
  • Remove all oils or other non-compatible sealers or treatments
  • Do not apply coating unless the concrete has cured at least 28 days @ 21 C and 50% relative humidity or equivalent

Stainless Steel

  • Surface profile should be a dense angular 1-3 mils and is best achieved through abrasive blasting in accordance with SSPC-SP16
  • Remove all contaminants that would interfere with the performance of stainless steel for the intended service such as, but not limited to, embedded iron or chlorides

For immersion (including potable water) use Thinner 38 up to 8% by volume
Pot Life: 3 hours at 24°C and less at higher temperatures
Pot life ends when coating becomes too viscous to use

Tip Size: 0.017-0.021" (0.43-0.53 mm)
Fluid Pressure: 2000-2500 psi (13.8-17.2 MPa)
Brush and Roller (General): For 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 24°C. Use a short-nap synthetic roller cover with phenolic core

Health and Safety


Clean Up

  • Use Carboline 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
  • 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
