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).

• Low temperature cure (20°F)
• Excellent moisture tolerance during application
• Fast cure response

Product Specification

Drying Times

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.

• 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

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.
• 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.
