Carboline Carboguard 690 GF is a high performance, glass-flake filled, cold cure epoxy having excellent film strength and resistance to water, salt 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. Glass flake reinforcement enhances film strength, impact resistance and barrier properties.

Can be used on a variety of surfaces including structural steel, piping, pilings, ships, offshore structures, and other 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.

Product Specification

Drying Times

Schedule above based on 50% relative humidity and 10-15 mil (250-375 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.

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: 2.0-4.0 mils (50-100 microns) (See Limitations).
• Non-immersion: SSPC-SP6; Surface Profile: 1.5-3.0 mils (38-75 microns). In certain situations, SSPC-SP3 is acceptable for thicknesses up to 10 mils (250 microns).

Concrete or CMU

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

Application Methods

Application Conditions

• 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.
• See Brush or Roller above
• Special thinning and application techniques may be required above or below normal 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 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.
