Application Instruction
˙Surface preparation
| General | Remove dirt, dust, oil and all other contaminants that could interfere with adhesion of the coating. Surfaces must be clean and dry. Moisture, grease, sludge, dust, corrosive salt must be thoroughly cleaned from substrate. |
|
Primed Surfaces
Areas of Breakdown and Damage | UP-450 should always be applied over a recommended anti-corrosive coating scheme. The primer surface should be dry and free from all contamination and UP-450 must be applied within the overcoating intervals specified (consult the relevant product data sheet). It should be prepared to the specified standard (Sa2 1/2 (ISO 8501-1:2007) or SSPC-SP6, Abrasive Blasting or SSPC-SP11, Power Tool Cleaning) and patch primed prior to the application of UP-450. |

|
˙Mixing & Thinning
| Mixing Thinning Mixing Ratio Pot life | Mix base and hardener according to the mixing ratio and stir thoroughly. Use PU Thinner (No.736) to thin up 5~15%. Base : Hardener = 88 : 12 ( by weight )Some individual colors may be different. 3 hours at 25℃ ( mixture, 77℉) |
˙Equipment
| Spray Application
Airless Spray
EPDM71UP450XV1.5
| Avoid applying the paint in rainy or humid weather (the moisture above 85% RH), otherwise the adhesion will be affected by moisture of substrate and the paint film will be loss its gloss. All equipment must be cleaned immediately after use. When overcoating interval is exceeded, paint surface must be roughened to insure adhesion. Hardener cover must be tightly closed to avoid reaction with moisture in air to form bubbles and gelation. Pump ratio 30:1 or greater Tip size : 0.015’’~ 0.019’’ Output PSI : 2100~2500 |

˙Environment conditions
| Condition | Coating | Surface | Environment | Humidity |
| Normal | 20~30℃(68℉~86℉) | 20~30℃(68℉~86℉) | 20~30℃(68℉~86℉) | 30~55% |
| Minimum | 5℃(41℉) | 5℃(41℉) | 5℃(41℉) | 0% |
| Maximum | 35℃(95℉) | 42℃(108℉) | 42℃(108℉) | 85% |
Industry standards are for substrate temperatures to be 3℃(5℉) above the dew point . the product simply requires the substrate temperature to be above the dew point.
Caution : This Product is moisture sensitive in the liquid stage and until cured. Protect from high humidity ,dew and direct moisture contact until cures. Application and/or curing in humidities above maximum, or exposure to moisture from rain or dew may result in a loss of gloss and/ormicrobubbling of the product.
˙Curing Schedule

| 15℃ (59℉) | 10 hours | 10 hours |
| 25℃ (77℉) | 4 hours | 4 hours |
| 35℃ (95℉) | 1.5 hours | 1.5 hours |
˙Cleanup & Safety
| Cleanup
Safety Ventilation | Use PU Thinner (No.736) to clean. In case of spillage, absorb and dispose of in accordance with local applicable regulations. Please read and follow all caution statements on this product data sheet and MSDS for this product. Proper ventilation and protective measures must be provided during application and drying to keep solvent vapor concentrations within safe limits and to protect against toxic or oxygen deficient hazards. |
