4. Precaution before Application
1. Please wipe clean the objects before application
2. Please make sure that the coating is well stirred.
3. Please make sure the compressor is well maintained.
4. After wipe with solvent, please make sure that the to be coated object is being coated within short period of time to prevent oxidation and forming rust.
5. Please keep the lid on after use to prevent air moisture from entering the container.
6. Please let the plate sit for 1 hour after application so that the surface of coating is level before any experiment.
7. Please let the objects sit for 8 hour before the 500°C high temperature resistance test.
5. Coating Storage
1. Please store in an ventilated area out of direct sunlight, keep at room temperature for up to 6 months.
2. Please keep a rule of first in first out when using the coating.
6. Other Precaution
Similar as other coating, when using this coating, please wear goggles, respirator, and latex glove, if your skin and eye got into contact with the coating accidentally, please flush with lots of water, attend the victim to medical service as soon as possible when necessary.
7. Coating Tests Performance
Product Name | DFR-P50 High temperature (500°C ) resistance coating | |
Testing Method | Testing Specification | Testing Result |
Hardness | Using Mitsubishi Pencils, Applying 1 kg force, hardness more than HB and above. | EXCELLENT |
Cohesiveness | 100*100 *1mm box, stick and tear off with duct tape, ALL coating attached, None is detached. | EXCELLENT |
Impact Resistance | DUPON Impact Resistance Machine, 500g at 20 cm height. NO Crack developed | EXCELLENT |
Water Resistance | Experimental plate simmered in water for 48 hour at 40C, observing the surface after 48 hour. | NO bubbling, mound or valley developed, coating appearance remains the same. |
Salt Water vapour Resistance | 5% NaCl salt water vapour, make cross, exposed for 120 hour. | NO bubbling, detached, or rust developed. |
High Temperature resistance | Coated experiment plate exposed under 500C for 24hour, check its cohesiveness, appearance, color, and any detachment. | Cohesiveness, appearance, color maintained, NO detachment. |
Heat Cycle Resistance |
| EXCELLENT |
Cold temperature test | Coated experimental plate placed in a fridge for 2 hour at -10C+2C, take out and sit for 1 hour at room temperature, run a cohesiveness test, check its appearance, color, and check for any detachment of the coating. | EXCELLENT |
Storage Stability | Initial Viscosity 45 sec (NK-2 cup), place at 65 C for 5 days, cool down back to 28C, viscosity only up 1 sec. To 46 sec. | EXCELLENT |

8. Comparison of DFR-P50 Black 500 with Imported coating, XYZ
COMPARISON OF DFR-P50 Black High Temperature resistance Coating with IMPORTED High Temperature Resistance Coating, XYZ | |
Color Depth (BLACK) | DFR P-50 is much darker than XYZ |
Application Effeciency | DFR P-50 can be applied in Single coat, XYZ need to be applied two coat; hence DFRR P-50 is more efficient in application and economical. |
Impact Resistance | 500g weight at 40 cm height Impact, there is no crack to be found on DFR P-50, but there is crack found on the XYZ. |
Water Resistance | Simmered in 40C water for 48 hour, no significant changes on DFR P-50, but the there is significant loss of glossiness on XYZ. |
Salt Water Vapour Resistance | There is minimum coating detachment on DFR P-50 but, major detachment, bubbling, and rust occurred on the XYZ plate. |
Hardness | At HB Pencil hardness, XYZ fail the test and the coating detached, but DFR P-50 has no significant effect. |
CONCLUSION | DFR P-50 is performing better than all the requirement, even the existing import product such as XYZ. |
