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.

Features and Benefits

• Ready to apply after mixing; no sweat-in time or thinning required
• Economical fit for use epoxy
• Used as a primer or intermediate coat
• Can be applied overpower tool cleaned surfaces
• Micaceous iron oxide (MiO Filler) for additional barrier properties and corrosion resistance: MiO is purchased separately
• Optional low temperature (LT) cure Part B
• VOC compliant to current AIM regulations

Product Specification

Drying Times

• 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

Application Conditions

• 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
