Drying Times
| Curing Schedule | |||
|---|---|---|---|
| Surface Temp | Dry to Handle | Dry to Topcoat | Final Cure General |
| -18°C | 4 Hours | 7 Days | NR |
| 4°C | 1 Hour | 2 Days | 4 Days |
| 16°C | 45 Minutes | 24 Hours | 3 Days |
| 27°C | 45 Minutes | 18 Hours | 2 Days |
| 38°C | 15 Minutes | 16 Hours | 36 Hours |
- 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
| Product Information | |
|---|---|
| Mixing: | Power mix base, then combine and power mix as follows. Pour zinc filler very slowly into premixed base with continuous agitation. Mix until free of lumps. Pour mixture through a 30 mesh screen. Sifting zinc through a screen will aid in the mixing process by breaking up or catching dry zinc lumps |
| Do not mix partial kits | |
| Thinning: | May be thinned up to 5 oz/gal (4%) with Thinner 26 or Thinner 33 for ambient and warm surfaces |
| In cool weather (below 4°C), thin up to 7 oz/gal (6%) with Thinner 21 | |
| 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 Gal. Kit
5 Gal Kit
|
| Pot Life: | 8 Hours at 24°C and less at higher temperatures. Pot life ends when coating becomes too viscous to use |
| Spray Application: | Keep material under mild agitation during application. If spraying stops for more than 10 minutes, recirculate the material remaining in the spray line. Do not leave mixed coating in the hoses during work stoppages |
| Conventional Spray: | Agitated pressure pot equipped with dual regulators, 3/8” (0.95 cm) I.D. minimum material hose, with a maximum length of 50 feet; 0.070” (0.18 cm) I.D. fluid tip and appropriate air cap |
| Airless Spray: | Pump Ratio: 30:1 min |
| Volume Output: 3.0 gpm min | |
| Material Hose: 3/8” (0.95 cm) I.D. min | |
| Tip Size: .019-.023” | |
| Output PSI: 1500-2000 | |
| Filter Size: 60 mesh | |
| Brush: | For touch up of areas less than one square foot only. Use medium bristle brush and avoid over brushing |
| Roller: | Do not apply by roller |
Application Conditions
| Product Conditions | |||||
|---|---|---|---|---|---|
| Condition | Material | Surface | Ambient | Humidity | |
| Minimum | -18°C | -18°C | -18°C | 30% | |
| Maximum | 54°C | 93°C | 54°C | 95% | |
- 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
