Note: Curing below metal temperatures of 190°C, or above metal temperatures of 210°C are not recommended.
After provide full cure for 15 minutes at 200°C metal temperature, wooden patterns and marble
finishes are created by appliying a top coat through a sublimation decoration technique.

Theoretical spreading rate at recommended film thickness (70 µm)
9 – 12 m2/kg. Practical spreading rates will vary due to such factors as method and conditions of
application, specific gravity and surface profile.
Application Guide
Surface Preparation
All surfaces should be degreased and pre-treated for optimal performance.
Suitable pre-treatment includes:
Aluminium
Yellow chromate or green chromate/phosphate
Ferrous metals
Zinc phosphate or Iron phosphate
Zinc Coated Metals
Zinc phosphate or chromate
Application Procedure and Equipment
1- PU44 series powder coatings charging properties are optimized when powder is free-flowing
and moisture-free. Aged or compacted powder may require pre-conditioning for several
minutes to fluidise evenly.
2- If storage room temperature is lower than the application area, powder coatings, which are
hygroscopic, should be acclimated in unopened containers prior to adding into the spray
hopper. For optimum performance, It should be applied and stored at air-conditioning area.
Storage temperatures should be kept below 30 °C.
3- Powder should not be stored in hoppers for long periods of time. If moisture condensation
occurs, fluidize powder to dry-out or replace moisture-laden powder with virgin powder.
4- Powder coatings are finely ground particulates. Respirators or dust masks should be used by
workers exposed to powder in order to avoid dust inhalation.
5- Compresed air to the gun must be oil and moisture free.
6- Silicone sould not be used in application area.
7- For box feeders, ensure probe is fully inserted in powder and operated as per manufacturer’s
recommendations.
8- Contact points should be maintained to ensure metal-to-metal ground.
9- Apply by electrostatic spray. Relative humidity should be 50-60% for corona system, lower than
40% for tribo system.

Cure as per recommendations outlined above.
Reclaim-to-virgin ratios should be carefully monitored to maintain spray consistency.
Sieving powder before adding to hopper eliminates potential clumping or foreign matter.
After provide full cure, wooden patterns and marble finishes are created by appliying a top coat
through a sublimation decoration technique. For more detailed, please contact your system
manufacturer’s.
Care and Maintenance
PU44 should be regularly washed with warm water and mild liquid detergent, followed by a fresh
water rinse to maintain the attractive appearance of the powder cured film.
The use of abrasive cleaners is not recommended, nor is the use of active organic solvents.
Health and Safety
PU44 The MSDS is an integral part of using this product as it contains information on the potential
health effect of exposure, personal protective equipment needed.
Powder-in-air concentrations of greater than 20 gr/m3 to 70 gr/m3 can be ignited by flame or strong
electrical discharge. Powder concentrations below 20 gr/m3 or above 70 gr/m3 are too sparse or too
dense to support flame or combustion. Properly engineered application equipment is designed to
keep powder-in-air concentrations well below this range. All equipment should be inspected
periodically for proper operation and electrical ground. Hangers, hooks, racking system, and
conveyor should be cleaned to eliminate powder build-up. Eliminate all sources of ignition.
Precautions and Limitations
-
-
As a result of possible wide application variations and stoving conditions, PU44 may show
variation, between İBA Kimya Powder Coatings prepared samples and production applied
material. Therefore, it is the applicator and/or their customer’s responsibility to ensure the
product conforms to their requirements.
For optimum corrosion performance ensure recommended dry film thickness is obtained.
Not recommended for use in highly corrosive environments.
The heat up rate of components in the curing oven may influence gloss difference.
