Description

Carboline Carboguard 893 SG MIO is a corrosion resistant coating with zinc phosphate corrosion inhibitor. Contains additional filler reinforcement (micaceous iron oxide) for enhanced barrier resistant properties. Used either as a primer or intermediate coat over steel, other epoxies, or inorganic zinc primers. May be topcoated with a broad variety of high-performance finish coats. Has surface tolerant properties. Has optional (LT) cure for 1.6°C cure capability.

Product Specification


Technical Data
Carboline Carboguard 893 SG MIO
Volume Solids: 64% +/- 2%
Theoretical Coverage Rate: 25.2 m²/l at 25 microns
8.4 m²/l at 75 microns
5.0 m²/l at 125 microns
Allow for loss in mixing and application
Dry Film Thickness: Two coats at 75-125 microns per coat may be used direct-to metal
Do not exceed 250 microns in a single coat. Excessive film thickness over inorganic zincs may increase damage during shipping or erection
Dry Temperature Resistance: Continuous: 149°C
Discolouration and loss of gloss occurs above 100°C but does not affect performance
Primer:

Self-priming

May be applied over organic and inorganic zinc rich primers. A mist coat may be required to minimize bubbling over zinc rich primers

Topcoats: May be coated with acrylics, epoxies, alkyds, or polyurethanes depending on exposure and need
Limitations: Epoxies lose gloss, discolour and eventually chalk in sunlight exposure.
Not recommended for immersion service.
Shelf Life: Part A & B: Min. 36 months at 24°C
MiO Filler: Min 60 months at 24°C
Storage Temperature and Humidity: 4°- 43°C
0-100% Relative Humidity

Test Method System Results
ASTM D4541 Adhesion Blasted Steel 1ct. 893 SG 1600 psi (Pneumatic)

Drying Times


Curing Schedule
Surface Temp. Dry to Recoat Maximum Recoat Time
10°C 24 Hours 365 Days</td
16°C 10 Hours 365 Days
24°C 7 Hours 365 Days
32°C 4 Hours 365 Days



  • These times are based on a 100-150 micron dry film thickness for non-immersion. 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
  • For force curing contact Rawlins on Tech - 0113 2455450 (option 2) or [email protected] Sales - 0113 2455450 or [email protected] for specific requirements



Surface Preparation


General

  • Surface 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

  • For most applications: SSPC-SP6 to obtain a blast profile of 25-50 microns
  • May also be applied over SSPC-SP 3 for certain applications

Concrete

  • Concrete must be cured 28 days at 24°C and 50% relative humidity or equivalent
  • Prepare surfaces in accordance with ASTM D42582 Surface Cleaning of Concrete and ASTM D4259 Abrading Concrete
  • Voids in concrete may require surfacing



Application Methods


Product Information
Mixing:

Power mix separately, then combine and power mix

DO NOT MIX PARTIAL KITS

Thinning: Normally not required but may thin as follows: Spray: Up to 15 oz/gal (12%) with Thinner 10

Brush & Roller: Up to 16 oz/gal (12%) with Thinner 33

Thinner 236 E may be used as an exempt thinner in lieu of those listed above.

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: 893 SG MiO: 1:1 Ratio (A to B) and MiO Filler at 2 lbs/gal
Pot Life:

4 Hours at 24°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, .070” I.D. fluid tip and appropriate air cap
Airless Spray: Pump Ratio: 30:1 (min)
GPM Output: 2.5 (min)
Material Hose: 3/8” (0.38 cm) I.D. (min)
Tip Size: 017-.021”
Output PSI: 2100-2300
Filter Size: 60 mesh
Brush and Roller (General):

Not recommended for tank lining applications except when striping welds. 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 24°C

Brush: Use a medium bristle brush
Roller: Use 3/8” nap phenolic core roller



Application Conditions


Product Conditions
Condition Material Surface Ambient Humidity
Minimum 10°C 10°C 10°C 0%
Maximum 32°C 52°C 43°C 80%



  • 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



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 respirator
  • Refer to the product data sheet and safety data sheet in the attachments section above for further details
