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 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).
Areas of It should be prepared to the specified standard (Sa2 1/2 (ISO 8501-1:2007) or SSPC-SP6, Abrasive Breakdown and Blasting or SSPC-SP11, Power Tool Cleaning) and patch primed prior to the application of UP-450. Damage
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 ) 3
hours at 25 |

Spray Application
Airless Spray
Brush
Roller |
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 Application by brush is applicable. For special condition please consult with product manufacturer. Application by brush is applicable. For special condition please consult with product manufacturer. |

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/or microbubbling of the product.
