Description
Carboline Thermaline 4900 Aluminium is a single package, air-dried coating available in colours and suitable for high temperature exposures up to 273°C. Air-drying characteristics allow for faster handling of in-shop applications than with other high-temperature coatings. Heat cure above 149°C is recommended and will impart added strength and integrity to the coating.

Product Specification
| Technical Data | |
|---|---|
| Carboline Thermaline 4900 Aluminium | |
| Primer: |
Self-priming on stainless steel, aluminium and metalized surfaces For carbon steel, apply over recommended zinc primer. A mist coating may be required to minimize bubbling over inorganic zinc primers |
| Topcoats: | Not applicable |
| Solid(s) Content: | By Volume 48% +/- 2% |
| Theoretical Coverage Rate: |
18.9 m²/l at 25 microns 12.6 m²/l at 38 microns 9.4 m²/l at 50 microns Allow for loss in mixing and application |
| Dry Film Thickness: |
38 - 51 microns per coat Don't exceed 63 microns in a single coat Excessive film thickness over inorganic zincs may increase damage during shipping or erection |
| VOC Values: |
As Supplied: 456 g/l Thinner 235: 22 oz/gal (17%): 503 g/l Thinner 25: 22 oz/gal (17%): 517 g/l These are nominal values and may vary slightly with colour |
| Flash Point: | 25°C |
| Shelf Life: | 24 months at 25°C |
Drying Times
| Curing Schedule | ||||
|---|---|---|---|---|
| Surface Temp. | Dry to Topcoat with Itself | Dry to Touch | ||
| 25°C | 4 Hours | 1 Hour | ||
- These times are based on a 2.0 mils (50 micron) dry film thickness. Higher film thickness, insufficient ventilation or cooler temperatures will require longer cure times and could result in solvent entrapment and premature failure
- While Thermaline 4900 is an ambient temperature cure coating, optimum performance properties are achieved when final heat cure occurs at 149°C after 3 hours
- After a 2-hour flash off at 24°C allow temperature to increase slowly to 149°C and hold it there for approximately 3 hours
Surface Preparation
| Preparation | |
|---|---|
| General: |
Surfaces 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: |
SSPC-SP10 with 0.5-1.0 mils (12-25 microns) surface profile Prime with specific Carboline primers as recommended by Rawlins on Tech - 0113 2455450 (option 2) or [email protected] |
Application Methods
| Product Information | |
|---|---|
| Mixing: | Thoroughly mix to a uniform consistency prior to use |
| Thinning: |
Normally not required May be thinned up to 22 oz./gal. (17%) by volume with Thinner 25 for ambient conditions. For “hot” applications exceeding 66°C use Thinner 235 instead Use Thinner 238 up to 5% (6 oz) for brush or roller application. (Note: Shake Thinner 238 just prior to use). 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: | N/A |
| Conventional Spray: | Use DeVilbiss P-MBC, E-needle and tip, and a 704 air cap or equal. Use adequate air volume for proper equipment operation. Hold gun 10-12” from the surface and at right angles. Lap each pass 50%. Apply 4.0-5.0 wet mils to obtain desired dry film |
| Airless Spray: | Not recommended |
| Brush and Roller: |
Recommended for touch-up of small areas or where spray application is not permitted Avoid excessive re-brushing or re-rolling |
| Brush: | Not recommended due to final appearance |
| Roller: | Not recommended due to final appearance |
Application Conditions
| Conditions | ||||
|---|---|---|---|---|
| Condition | Material | Surface | Ambient | Humidity |
| Minimum | 13°C | 4°C | 4°C | 0% |
| Maximum | 35°C | 149°C | 49°C | 90% |
- 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
- The alignment of aluminium flakes in aluminium filled finishes is very dependent on application conditions and techniques
- Care must be taken to keep conditions as constant as possible to reduce variations in final appearance
- It is also advisable to work from a single batch of material since variations can occur from batch to batch
- For more information consult Rawlins on Tech - 0113 2455450 (option 2) or [email protected]
