• Meets SSPC Paint 20 Type I, Level 1 for zinc content

Product Specification

Drying Times

• These times are based on a 75-100 micron dry film thickness. Higher film thickness, insufficient ventilation and/or cooler temperatures will require longer cure times and could result in solvent entrapment and premature failure
• Humidity levels below 50% will require longer cure times
• Notes: Maximum recoat time is unlimited
• Must have a clean, dry surface free of chalk, zinc salts, etc per typical good painting practices
• Loose zinc must be removed from the cured film by rubbing with fiberglass screen wire if: 1) The Carbozinc 11 is to be used without a topcoat in immersion service and "zinc pick up" could be detrimental, or 2) When "dry spray/overspray" is evident on the cured film and a topcoat will be applied
• For accelerated curing or where the relative humidity is below 40%, allow an initial 2-hour ambient cure followed by misting with clean potable water or steam to keep the coating wet for a minimum of 8 hours. The coating is considered cured sufficiently to topcoat and/or immersion service when the coating achieves a "2H" pencil hardness per ASTM D3363 or a minimum rating of 4 per ASTM D4752
• Recoat intervals may vary from those listed above when using under intumescent fireproofing products
• Consult Rawlins on Tech - 0113 2455450 (option 2) or [email protected] for recommended cure times before applying Carboline intumescent products

Surface Preparation

General

• Remove all oil or grease from the surface to be coated with Thinner 2 or Surface Cleaner 3 (refer to Surface Cleaner 3 Instructions) in accordance with SSPC-SP1

Steel

• Non-Immersion: SSPC-SP6 and obtain a 25-75 micron angular blast profile
• When using under fireproofing products, defer to the primer surface preparation requirements in the product data sheet of the fireproofing product

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 21 or Isopropanol
• 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 sheets for this product and use personal protective equipment as directed
• 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
• In addition to ensuring proper ventilation, appropriate respirators must be used by all application personnel

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