Polyurethane Powder Coatings

General: Polyurethane Powder Coatings-JC600 Series products mainly composed by polyurethane as base material, used in outdoor applications. Air Conditioner outdoor facilities, Garden Tools, outdoor lightings, Building wall, Door/Window frame, Ceiling, Guardrail, Sports Equipments, Leisure Furantures etc. It has a very good performance of anti-corrosion andbend propeties. JC600 series have very smooth surface and high glossy, it meets applications of high surface quirement. Powder Properties: Chemical Type: Polyurethane Particle Size: Suitable for electrostatic painting Specific Gravity: 1.2-1.7 g/cm3 (depending on pigmentation) Storage Condition: Keep in cool & dry place Validity: 6 months (25°C) Products Code: JC600 Series Curing Condition: 200°C 10min. / 190°C 15min. Testing Conditions: Checked under laboratory conditions. Actual product performance may vary due to product specific properties such as gloss, color, effect and finish as well as application related and environmental influences.

Determination of resistance to Humidity BS3900-F2 (1000h) No blistering or loss of gloss Soaked in distilled water Test BS3900-F7 (240h) No blistering or loss of gloss Anti-chemicals (tested by normal acid, alkali, oil, solvents under room tempeture.) Good Outdoor Duration 24 months Florida exposure A slight loss of gloss, but no chalking, remains superior protection. Note of Pretreatment: All the steel substrate should be degreased, the ferrous metals should be zinc or iron phosphating, aluminum recommended chromating, to improve corrosion resistance. Coating Method: JC600 series powder can be coated by manual or auto electrostatic spray guns. (or a tribostatic process as for option). it can be cycle used with a proper recycle system.
