Product Specification


Technical Data
Carboline Carboguard 890 LT
Volume Solids: 80% +/- 2%
Theoretical Coverage Rate: 1283 ft²/gal at 1.0 mils (31.5 m²/l at 25 microns)
321 ft²/gal at 4.0 mils (7.9 m²/l at 100 microns)
214 ft²/gal at 6.0 mils (5.2 m²/l at 150 microns)
Allow for loss in mixing and application
Dry Film Thickness: Use 6-8 mils (152-203 microns) over tight rust or severe environments. Do not exceed 10 mils (250 microns) in a single coat. Excessive film thickness over inorganic zincs may increase damage during shipping or erection.
Primer: Self-priming. May be applied over inorganic zinc primers and other tightly adhering coatings. A mist coat may be required to minimize bubbling over inorganic zinc primers.
Topcoat: May be coated with acrylics, epoxies, or polyurethanes depending on exposure and need.
VOC Values: As supplied: 1.5 lbs/gal (180 g/l)
Thinner 2: 15 oz/gal = 2.0lbs/gal (250 g/l)
Thinner 33: 14 oz/ga l= 2.0 lbs/gal (250 g/l)
These are nominal values and may vary slightly with colour
Flash Point: 89°F (32°C) for Part A
73°F (23°C) for Part B
85°F (29°C) for mixed
Limitations: Do not apply over acrylic or alkyd coatings. If discolouration is objectionable it may be top coated. Use only factory-made colours for splash zone or immersion service.
Shelf Life: Part A: Min. 36 months at 75°F (24°C)
Part B: Min. 15 months at 75°F (24°C)
Storage Temperature and Humidity: 40° - 110°F (4° - 43°C)
0-100% Relative Humidity

  • 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.
  • During high humidity conditions, it is recommended that the application be done while temperatures are increasing.
  • Maximum recoat/topcoat times are 30 days for epoxies and 90 days for polyurethanes at 75°F (24°C). 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.



Surface Preparation


Steel

  • Minimum SSPC-SP6 for most applications
  • Profile: 1.5-3.0 mils (38-75 microns), SSPC-SP2 or SP3 are suitable cleaning methods for mild environments.

Galvanised Steel

Concrete or CMU

  • The concrete must be cured for 28 days (at 75°F/50% R.H.) or until the concrete reaches its designated compressive strength.
  • Prepare and clean the surface in accordance with SSPC-SP13/NACE No. 6 guidelines.
  • Test for moisture by conducting a plastic sheet testing in accordance with ASTM D4263

Dry Wall and Plaster

  • Joint compound and plaster should be fully cured prior to coating application.

Previously Painted Surfaces

  • Lightly sand or abrade to roughen surface and de-gloss the surface.
  • Existing paint must attain a minimum 3B rating in accordance with ASTM D3359 “X-Scribe” adhesion test.



Application Methods


Product Information
Mixing: Power mix separately, then combine and power mix. DO NOT MIX PARTIAL KITS.
Thinning: Spray: Up to 13 oz/gal with Thinner 2
Brush or Roller: Up to 14 oz/gal with Thinner 33
Thinner 33 can be used for spray in hot/windy conditions. Use of thinners other than those supplied or recommended by Carboline may adversely affect product performance and void product warranty, whether expressed or implied.
Ratio: 1:1 Ratio (A to B)
Pot Life: 2 Hours at 75°F (24°C) Pot life ends when coating loses body and begins to sag. Pot life times will be less at higher temperatures.
Spray Application (General) This is a high solids coating and may require adjustments in spray techniques. Wet film thickness is easily and quickly achieved.
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)
GPM Output: 3.0 (min)
Material Hose: 3/8” I.D. (min)
Tip Size: 0.017”-0.021”
Output PSI: 2100-2300
Filter Size: 60 mesh
Brush and Roller (General): Multiple coats may be required to obtain desired appearance, recommended dry film thickness and adequate hiding. Avoid excessive re-brushing or rerolling. For best results, tie-in within 10 minutes at 75°F (24°C).
Brush: Use a medium bristle brush
Roller: Use a short-nap synthetic roller cover with phenolic core
