Black Silver Epoxy Polyester Interier Use Spray Powder CoatingDescriptionepoxy polyester ral colors powder coating use for indoor/outdoor envirnment, can be use for metal, steel, aluminum products.
It is usually used to create a hard finish that is tougher than conventional paint. Powder coating is mainly used for coating of metals, aluminum extrusions, and automobile and bicycle parts.The Powder Coating Process involves three basic steps:
1.Part preparation or the pre-treatment = Removal of oil, soil, lubrication greases, metal oxides, welding scales etc. is essential prior to the powder coating process. It can be done by a variety of chemical and mechanical methods. The selection of the method depends on the size and the material of the part to be powder coated, the type of soil to be removed and the performance requirement of the finished product.2. The powder application - The most common way of applying the powder coating to metal objects is to spray the powder using an electrostatic gun, or corona gun. The gun imparts a positive electric charge on the powder, which is then sprayed towards the grounded object by mechanical or compressed air spraying and then accelerated toward the workpiece by the powerful electrostatic charge. 3. Curing - When a thermoset powder is exposed to elevated temperature, it begins to melt, flows out, and then chemically reacts to form a higher molecular weight polymer in a network-like structure. This cure process, called crosslinking, requires a certain temperature for a certain length of time in order to reach full cure and establish the full film properties for which the material was designed. Normally the powders cure at 200°C (390°F) for 10 minutes. The curing schedule could vary according to the manufacturer's specifications. The application of energy to the product to be cured can be accomplished by convection cure ovens or infrared cure ovens.Product Test
