Product name:
Polyester Resin Powder Coatings Spray Paint
Introduction
This coating uses a "Primid" type curing agent, developed as an alternative to TGIC curing systems. These coatings are used on a decreasing basis, primarily due to appearance issues at heavy film thicknesses.
New raw materials and processes are continuously evaluated for ongoing product development and enhancement — improved properties, lower cost!
Appearance
There are various appearance,from low gloss to high gloss.
Special Appearance:Texture,sand,metallic or pearl,mixed color,other special appearance upon request.
Physical properties
Special gravity:1.2-1.8(depending on the gloss and color)
Distribution of powder size:100% less than 100 micron (can be adjusted by the application requirement)
Flowability: 120-140
Volatility <0.8%
Cure condition
200ºC(Object temperature)/10mins
180ºC(Object temperature)/15mins
Typical Performance Properties
All the tests as follows are carried out on 0.8mm steel panel with the film thickness of 50-70 microns.
Test Item | Method | Standard | Target |
Gloss | 60°Gloss Tester | GB/T9754-1988 | +/- 5% |
Film thickness | Film thickness Tester | GB1764-1979 | 60um-70um |
Adhesion | Cross-cut Tester | GB/T9286-1998 | 0 Grade |
Film Hardness | Film Hardness Tester(Japan) | GB/T6739-1996 | 1H-2H |
Impact | Impact Tester | GB/T1732-1993 | 50cm*kg Positive Impact(According to Gloss) |
Mandrel Bend | 180°Bend | GB/T6742-1986 | 2mm-3mm |
Cupping test | Erichsen tester | GB/T9753-1988 | 5mm-6mm |
Color Difference | Color Difference Tester | GB/T11186.2-89 | Dark<1.5,Light<0.5 |
Salt spray | Salt spray Tester | GB/T1771-1991 | 500h |
Humidity Test | Constant temperature and humidity | GB/T1740-1979 | 500h,Changes<1 Grade |
Bucholz Hardness | Bucholz Hardness Tester | GB/T 9275-1988 | ≥80(Length:1.15-1.2) |
Surface | Visual | GB/T 9761-1988 | No Particle above 60um |
The distribution of Particle Size | Laser particle sizer | / | D(4,3) 35-40um |
Remark:
1)Gloss: Can be adjust from 0 to 95 according to the request of customer
2)Impact: Different gloss has different resistance capability of impact
Smooth:50Kg.cm, Low gloss:40Kg.cm
3)Mandrel Bend: The capability of bend is according to the gloss
4)The distribution of Particle: Use LS-POP(III)Laser particle sizer, it has no standard of tester method defined by the nation.
5)Salt spray and Aging resistance: Will test according to client's request.
6)Cup-process tests may vary slightly depending on the glossy and surface effect of the product, with matte, reluster, and sand-grained cup-processes generally being slightly smaller than high-gloss powders
Average Coverage
9-12 square meters per kilogram at the film thickness of 60 microns.(at 100% powder utilization)
TGIC&Primid
Both TGIC & Primid system are available, we can supply as your requested.
