Application details
Surface preparation: Remove any oil, grease, dirt and any other contaminants from the surface before painting by proper method such as solvent cleaning and fresh water washing, etc.
Preceding coat: Korepox H.B EH6270 or according to specification.
Method of application: Spray (Airless or Air), Roller or Brush application.
For airless spray application ;
Nozzle orifice : 381 ㎛ ~ 533 ㎛ (0.015″ ~ 0.021″)
Output pressure : 11.7 MPa ~ 15.2 MPa
Fan : 40 ˚ ~ 60 ˚
(Airless spray data are indicative and subject to adjustment)
Mixing: Base (Part A) : Curing Agent (Part B) = 7 : 1 (by volume)
Mix thoroughly together prior to application in the proportions with power agitator as delivered.
Thinning: Thinner No. 0624, 037U Do not dilute each components separately, only the mixture.
Application conditions: The surface should be cleaned and dried completely. Do not apply when relative humidity is above 85 %.
The surface temperature should be at least 2.7 ℃ (5 ℉) above dew point to prevent condensation. In confined spaces, ventilate with clean air during application to assist solvent evaporation.
Film thickness: 40µm dry. Maybe specified in another film thickness than indicated depending on purpose and area of use.
Drying time:
| Substrate temperature | 5 ℃/41 ℉ | 20 ℃/68 ℉ | 30 ℃/86 ℉ |
| Set to touch | 7 h | 2 h | 1 h |
| Dry through | 48 h | 24 h | 18 h |

The actual drying time is subject to the film thickness, ventilation, humidity etc., and drying time under other temperature conditions should be checked and informed by KCC.
Pot life: 3 h at 20 ℃/68 ℉
Recoating interval: At 20 ℃/ 68 ℉, Minimum : 18 h
Maximum : Free
Prior to overcoating, remove the oil, salts, chalking materials and any other contaminants on aged coating film completely by proper cleaning method such as solvent cleaning and/or fresh water washing.
Heat resistance temperature: Continuous : 93 ℃/200 ℉ (Non-immersion service)
Non-continuous : 121 ℃/250 ℉ (Non-immersion service)
Storage and package
Shelf life: 12 months
Packing Unit: 16 L (UT6581 -A : 14 L, UT6581-B : 2 L)
Remarks
Note: Do not store at temperature below 5 ℃/41 ℉ or above 40 ℃/104 ℉.
Protect skin and eyes from direct contact with liquid paint, and avoid prolonged breathing of solvent vapors.
Use with adequate ventilation.
Respiratory protection is recommended when applying this product in confined spaces or stagnant air.
If you apply metallic colour(RAL9006(H), Semi-gloss) as T/UP, colour difference could occur.
So please contact technical department before the application.
