    Description

    Carboline Carboguard 891 VOC is a two-component, ultra-high solids epoxy that is designed as a liner for potable water, demineralized water, wastewater, and many other services. It is widely used as a tank lining for steel and concrete tanks.

    Product is self-priming and is normally applied in two coats. Formulated for application at conventional builds (4 to 6 mils per coat) as well as high builds (10 mils per coat).

    • These times are based on a 150-175 micron dry film thickness. 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 discolouration, 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
    • Food-grade exposures require force curing at 225°F for four hours. Raise temperature 30°F for every 30 minutes until temperature is reached

    Surface Preparation


    General

    • Surfaces must be clean and dry
    • Employ adequate methods to remove dirt, dust, oil and all other contaminants that could interfere with adhesion of the coating

    Steel

    • Immersion: SSPC-SP10/NACE 2
    • Non-immersion: SSPC-SP6/NACE 3
    • Surface Profile: 2-3½ mils (50-88 microns)

    Concrete or CMU

    • Immersion: Concrete must be cured 28 days at 24°C
    • Prepare surfaces in accordance with SSPC-SP13/NACE 6 or ICRI 03732 to obtain CSP 3 to 5 roughness
    • Attain a surface profile resembling extra coarse sandpaper
    • Eliminate leaks and infiltrations and remove standing water
    • Resurface areas with excessive cavities (bugholes) or exposed aggregate using a high-strength resurfacing product like Carboguard 510
    • Carboguard 510 may be used to patch bugholes and to resurface



    Application Methods


    Product Information
    Mixing:

    Power mix separately, then combine and power mix

    DO NOT MIX PARTIAL KITS

    Requires short 15 min sweat-in time

    Thinning:

    Thinning will be required to properly atomize the mixed material

    Thin up to 10% (13 oz/gal) with Thinner 225 E (VOC exempt thinner), Thinner 2 or Thinner 76 (for non-potable use only)

    Use of thinners other than those supplied by Carboline may adversely affect product performance and void product warranty, whether expressed or implied

    Ratio:2:1 Ratio (A to B)
    Pot Life:

    1¼ Hours at 24°C

    2 Hours at 15.5°C

    Pot life ends when coating loses body and begins to sag

    Pot life times will be less at higher temperatures

    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. Adjust air pressure to approximately 50 psi at the gun and provide 10-20 lbs. of pot pressure
    Airless Spray:

    Pump Ratio: 30:1 (min.)

    GPM Output: 2.5 (min.)

    Material Hose: 3/8” I.D. (min.)

    Tip Size: 0.017”-0.021”

    Output PSI: 1500-2300

    Filter Size: 60 mesh

    Brush and Roller:Recommended for small areas and repairs only. Use a high quality brush and apply a very light crisscross brush coat. Allow to dry for approximately 5 minutes. Then apply a heavy coat using a crisscross brush pattern. Normally, a film thickness of 62- 75 microns can be obtained per coat by this method
    Brush:Use a medium bristle brush
    Roller:Not recommended

    • This product simply requires the substrate temperature to be above the dew point
    • Condensation due to substrate temperatures below the dew point can cause flash rusting on prepared steel and interfere with proper adhesion to the substrate
    • Special application techniques may be required above or below normal application conditions
    • Note: Prior to spray application, stripe brush all weld attachments and surface irregularities using Carboguard 891 VOC thinned 10% by volume with Thinner 225 E



    Health and Safety


    Clean Up

    • Use Thinner 225E
    • 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 safety data sheet for this product and use personal protective equipment as directed
    • Employ normal workmanlike safety precautions

    Ventilation

    • When used 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 regulations
    • In areas where explosion hazards exist, workmen should be required to use non-ferrous tools and wear conductive and non-sparking shoes
    • Refer to the product data sheet and safety data sheet in the attachments section above for further details
