Description

Carboline Carboguard 635 VOC 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. It has low VOC and low HAP's content for use in areas with restricted volatile emissions.

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.

Drying Times


Curing Schedule
Surface Temp Dry to Touch Dry to Handle Dry to Topcoat Minimum Dry to Topcoat Maximum
20°F (-7°C) 4 Hours 36 Hours 24 Hours 180 Days
35°F (2°C) 2 Hours 18 Hours 2 Hours 180 Days
50°F (10°C) 1 Hour 11 Hours 1 Hour 180 Days
75°F (24°C) 30 Minutes 3 Hours 45 Minutes 180 Days
90°F (32°C) 15 Minutes 1.5 Hours 30 Minutes 180 Days



These times are to be used as a guideline for non-immersion applications.

  • The longer the first coat has to cure, particularly in sunlight exposure or elevated temps, the higher risk of inadequate adhesion. 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.
  • The listed times in the chart above are based on a 4-6 mil (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 0°F (-17°C) during its cure and will continue to cure when the temperature rises.

Cure for Potable Water Use

  • 7-day cure after final coat @ 75°F



Curing Schedule
Surface Temp Dry to Topcoat Minimum Dry to Topcoat with Antifoulant Maximum Dry to Topcoat with Itself
20°F (-7°C) 24 Hours 36 Hours 30 Days
35°F (2°C) 2 Hours 16 Hours 30 Days
50°F (10°C) 1 Hour 8 Hours 30 Days
75°F (24°C) 45 Minutes 4 Hours 30 Days
90°F (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 @75°F



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 1½-3 mil (40-75 micron) blast profile
  • Immersion Service: Minimum near white metal cleanliness in accordance with SSPC-SP10

Galvanised Steel

  • Galvanizing 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 @ 70 F (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.



Application Methods


Product Information
Mixing: Mix separately, then combine and mix until homogenous.
Ratio: 4:1 (Part A: Part B)
Thinning: For atmospheric applications thin up to 10% by volume with Carboline Thinner 242E, 236E, or 76. Use up to 10% with Thinner 33 for brush and roller.
For immersion (including potable water) use Thinner 38 up to 8% by volume.
Pot Life: 3 hours at 75°F (24°C) and less at higher temperatures.
Pot life ends when coating becomes too viscous to use.
Spray Application (General): This is a high solids coating and may require adjustments in spray techniques. Wet film thickness is easily and quickly achieved. The following spray equipment has been found suitable and is available from manufacturers. 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, 0.070” I.D. fluid tip and appropriate air cap.
Airless Spray: Pump Ratio: 30:1 (min.)
Volume Output: 2.5 gal/min (9.5 l/min)
Material Hose: 3/8" I.D. min (905 mm)
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 75°F (24°C). Use a short-nap synthetic roller cover with phenolic core.

  • Industry standards are for substrate temperatures to be above the dew point.
  • Carboguard 635 is unique in that it can tolerate damp substrates.
  • Special application techniques may be required above or below normal application conditions.
  • Special thinning and application techniques may be required above or below normal conditions.



Health and Safety


Clean Up

  • Use Carboline Thinner 2 or MEK.
  • 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
  • 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.
