Product Specification
| Technical Data | |
|---|---|
| Carboline Thermaline 4700 Aluminium | |
| Colour: |
Aluminium only (C901) 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] |
| Primer: |
Inorganic zincs None needed for stainless steel or aluminium |
| Solid(s) Content: | By Volume 30% +/- 2% |
| Theoretical Coverage Rate: |
11.8 m²/l at 25 microns 7.9 m²/l at 38 microns 5.9 m²/l at 50 microns Allow for loss in mixing and application |
| Dry Film Thickness: |
1.5 - 2 mils (38 - 51 microns) per coat Do not exceed 2.0 mils (51 microns) in a single coat One or two coats are typical. Two coats are recommended over stainless steel |
| VOC Values: |
As Supplied: 604 g/l Thinner 10: 16 oz/gal: 632 g/l Thinner 235: 12 oz/gal: 492 g/l |
| Limitations: |
Do not use for immersion service Do not exceed thickness recommendation Excessive film thickness may result in blistering and delamination when the temperature is increased |
| Flash Point: | 20°C |
| Shelf Life: | 12 months at 25°C |
Drying Times
| Curing Schedule | ||||
|---|---|---|---|---|
| Surface Temp. | Dry to Touch | Dry to Topcoat with Itself | Dry to Handle | |
| 24°C | 1 Hour | 4 Hours | 8 Hours | |
- These times are based on a 51 microns 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
- Excessive humidity or condensation on the surface during curing can interfere with the cure and may cause discoloration
- During high humidity conditions, it is recommended that the application be done while temperatures are increasing
- If the final cure time is exceeded, the surface must be abraded prior to the application of additional coats
- Full physical properties will be reached when heat curing has been completed
- After a 2 hour flash off at 24°C, allow temperature to increase at a maximum rate of 2°F per minute to 204°C
- Hold at 350°F to 177°C to 232°C for 2 hours
Surface Preparation
| Preparation | |
|---|---|
| General: | Remove all contaminants in accordance with SSPC-SP 1 |
| Steel: | Follow surface preparation for recommended or specified primer. When using direct to steel surfaces abrasive blast to minimum NACE No. 2/SSPC-SP10 with a 0.5 to 1.0 mil (12-25 microns) surface profile |
| Aluminium: | Clean and abrade per SSPC-SP 16 to achieve 12 to 25 microns surface profile |
| Stainless Steel: | Clean and abrade per SSPC-SP 16 to achieve a 12-25 microns surface profile |
Application Methods
| Product Information | |
|---|---|
| Mixing: |
Power mix to uniform consistency Avoid excessive air entrapment |
| Thinning: |
Normally not required May be thinned up to 32 oz/gal (25%) by volume with Thinner 235 for “hot” applications exceeding 66°C and for mist coating Use of thinners other than those supplied or recommended by Carboline may adversely affect product performance and void product warranty, whether expressed or implied |
| 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. Overlap each pass 50% |
| Airless Spray: | Not recommended |
| Brush and Roller: |
Recommended for touch up of small areas or where spray application is not permitted Avoid excessive brushing or rolling as this may result in a non-uniform appearance Brush and roller application may result in a streaky appearance due to orientation of the Aluminium pigment. For the best aesthetic appearance, spray application is required |
| Brush: | Use a medium bristle brush |
| Roller: | Use a short-nap mohair roller cover with solvent resistant core |
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
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
Ventilation
- When used 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
- Refer to the product data sheet and safety data sheet in the attachments section above for further details
