Description
Carboline Thermaline 4674 is a single package medium to high temperature coating that withstands continuous temperature up to 400ºC peaks up to 540ºC. May be applied directly to properly prepared steel. Application over inorganic zinc primers like Carbozinc 11 will provide superior performance by preventing rusting and rust streaking during a shutdown or when the equipment is exposed to moisture and/or salts at temperature less than 93ºC.

Product Specification
| Technical Data | |
|---|---|
| Carboline Thermaline 4674 | |
| Primer: |
None required A primer coat of Carbozinc will greatly increase performance over steel |
| Topcoats: | Normally none |
| Solid(s) Content: | By Volume 45 ± 2% |
| Theoretical Coverage Rate: |
11,2 m²/l at 40 µm Allow for loss in mixing and application |
| Dry Film Thickness: |
30 - 80 microns (1.18 - 3.15 mils) per coat Normally 40 µm. Two coats are recommended over bare steel and one or two coats over inorganic zincs such as Carbozinc 11 Excessive film thickness over inorganic zincs may result in blistering and delamination when temperature is increased. |
| Wet Film Thickness: | 65 - 175 µm per coat, normally 90 µm |
| Dry Temp. Resistance: |
Continuous: 400°C (752°F) Non-Continuous: 540°C (1004°F) |
| Limitations: | Not recommended for linings or immersion service and exposure to splash and spillage of acids and alkalis |
| Shelf Life: | 2 years at 24ºC |
Drying Times
| Curing Schedule | ||||
|---|---|---|---|---|
| Surface Temp. | Between Coats | Final Cure | ||
| 10°C | 8 Hours | 10 Hours | ||
| 16°C | 5 Hours | 8 Hours | ||
| 30°C | 2 Hours | 3 Hours | ||
- These times are based on 40 microns dry film thickness. Excessive film thickness or inadequate ventilation conditions after application require longer dry times and will cause premature failure in extreme cases
- Final cure: To obtain optimum properties, Carboline 4674 must be cured at temperatures of 177 – 232ºC. Allow for initial increase of temperature to proceed slowly up to 177ºC over a 6 hours period
Surface Preparation
| 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: | Abrasive blast cleaning to Sa 2½ (ISO 8501-1) is recommended with a blast profile of 25 – 40 µm |
| Aluminium: | Sweep blast cleaning (SSPC-SP16) is recommended |
| Stainless Steel: | Sweep blast cleaning (SSPC-SP16) is recommended |
Application Methods
| Product Information | |
|---|---|
| Mixing: |
Power mix to uniform consistency Avoid excessive air entrapment |
| Thinning: |
May be thinned up to 12% with Carboline Thinner 10 Use of thinners other than those supplied or approved by Carboline may adversely affect product performance and void product warranty, whether expressed or implied |
| Conventional Spray: | Pressure pot equipped with dual regulators, 3/8” I.D., minimum material hose .043” I.D. fluid tip and appropriate air cap |
| Airless Spray: |
Pump ratio: 30 : 1 (min.) GMP Output: 3.0 (min.) Material Hose: 3/8” I.D. (min.) Tip Size: .013-.015” Output PSI: 2200 Filter Size: 60 mesh |
| Brush: |
For small areas and touch-up only Use a medium natural bristle brush applying full strokes, avoid re-brushing |
| Roller: | Application by roller is not recommended |
Application Conditions
| Conditions | ||||
|---|---|---|---|---|
| Condition | Material | Surface | Ambient | Humidity |
| Minimum | 4°C | 4°C | 4°C | 0% |
| Maximum | 38°C | 54°C | 54°C | 95% |
- Industry standards are for substrate temperatures to be 3ºC above the dew point
- Special application techniques may be required above or below normal application conditions
Health and Safety
Clean Up
- Use Thinner 2
- 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 MSDS 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
