Polyurethane powder coating
Polyurethane powder coating: powder coating composed of hydroxyl polyester resin, blocked isocyanate, pigments and fillers, additives, etc.
Application of Polyurethane powder coating : suitable for all kinds of outdoor metal products, such as agricultural machinery, automobile parts, courtyard guardrail, sports equipment, industrial equipment, outdoor lamps, air conditioner, building materials, etc. compared with TGIC, it is safer, more environmentally friendly and healthier.
Characteristics of Polyurethane powder coating : the film has good leveling property, good wear resistance and chemical resistance, good adhesion to the coating substrate, good mechanical properties of the film, and is not easy to yellowing when baking.
Basic performance of Polyurethane powder coating :
Specific gravity: 1.2-1.7 [g / cm3] (different due to color and luster)
Particle size: according to different uses, the average particle size is 35-40 μm
Storage of Polyurethane powder coating: store in a dry room below 30 ℃, avoid direct sunlight, and store for 12 months under the condition of good packaging; after this period, it can still be used if it meets the requirements after inspection
Utilization rate: 8-12 m2 / kg, film thickness 70 μ m (100% utilization rate required). The actual spraying area will be different due to the different shape of coating equipment and workpiece
Transportation of Polyurethane powder coating: non dangerous goods, suitable for various modes of transportation, avoid long-term direct sunlight, avoid water, oil and other chemical pollution.
Coating effect of Polyurethane powder coating :
The appearance of the product has a variety of surface effects, according to the needs of customers can choose from low to high different gloss and special surface effects: such as various wrinkles, sand lines, metal effects, etc. (please refer to the company's powder coating effect color card), can also be customized according to the needs of customers (including special functional type).
