Polyester Powder Coating
 
Introduction
This series of product also call weatherability powder coating or outdoor type powder coating, that is mainly made of saturated polyester resin and curing agent. It has excellent performance in high-intensity ultraviolet ray and high moisture environment, good physical and mechanical property, outstanding temperature resistance and chemical resistance.
Series
1.Standard curing (200C/10min) and lower temperature curing is available
2. Made to various of gloss and color: high gloss (Above 86º), flat gloss (50~85º), semi gloss (10~49º)and no gloss (below 10º), gloss and color of product is made according to clients requirement.
3. Various kinds of art texture products are available, such as sandy, wrinkle, Antique, metal effect, etc.
4. Special standard of product is available according to clients’ requirement, e.g.: RoHS Standard, ASTM963 Standard, etc.
Application
This type of product specially designed for the outdoor metalwork that require good performance in the environment of high-intensity ultraviolet ray and high moisture, such as construction molding, advertisement board, outdoor metal furniture, lamp pile and fence in highway, etc.
Physical Property
Proportion: 1.4-1.8ɡ/㎝³ (varies with different color and gloss)
distribution:  average particle size is 30~38um, adjusted as clients required.
Performance of Coating Film

Testing Items Standards and Methods Result
Impact strength test GB/T1732-1993 50kg•㎝
Adhesion(cross-cut) GB/T9286-1998 Class 0
Bend test GB/T6742-1986 2mm
Pencil hardness GB/T6739-1996 1H-2H
Salt spray test GB/T1771-1991 >500 hours
Humid heat test GB/T1740-1979 >1000 hours, gloss slight loss
Weatherability test Acceleration light aging test QUV-B13,240h

Notation:  

1. All above tests are using 0.35mm cold rolling sheet. The thickness of film is 50-80um.
2. Performance of film may slightly decrease with decreasing in gloss.

Package
Carton packing with liner of double polyethylene bags. 20 Kg net weight each.
Storage
The product must be stored in ventilated, dry and clean room with temperature below 30℃, no close to fire and other heating source, avoid direct sunlight, outdoor stacking is prohibited. The period of validity is 12 months under above conditions; expired products can not be used unless re-testing meets the utilization standards.
Health and Safety
There are no hazardous ingredients in all materials of powder coating. Wearing anti-dust mask and goggles to avoid inhalation of dust and try best to avoid longtime contact with powder coating. The coating adhesive to the skin can be washed with soap.
Others
The performance of powder coating may have deviation in different conditions, please contact our engineers for suggestion.
