Painting is becoming outdated because it wears out fast, emits volatile organic compounds, and it is at times expensive. As such, alternative methods are being invented for coating surfaces for protective and aesthetic purposes. Powder coating which involves application of free-flowing dry powder is one of the methods that is currently gaining wide usage. Therefore when in need of professionals in powder coating Los Angeles is a nice place to consider visiting.
There are numerous advantages associated to powder coating as compared to other coating techniques like painting using conventional paints. Cleanliness and convenience in handling powder coat makes it better in many ways. The dry form prevents it from contaminated clothes and surfaces. Use of solvents is also not required.
Application involves using an application gun through electrostatic means. The gun imparts a positive charge into the powdery substance during emission. This causes the substance to be attracted to the negatively charged substrate. The two opposite charges result into a bond between the surface and the dust which is then cured through heating. The final finish created after curing is normally harder and tougher than that created by conventional paint.
This coating process can be applied on various surfaces and substrates including automobile parts, aluminum extrusions, bicycle parts, household appliances, and drum hardware among others. The surfaces may be made from different materials including wood, plastic, metal alloy, or metal. Medium density fiberboard can currently be coated due to improved technology. It is expected that more surfaces will be paintable using this coat in future.
There are two major types of powder coats, that is, thermoplastics and thermosets. The formula of the thermosetting variety includes a cross-linker. Performance is improved through reaction with other chemicals within the substance to cause polymerization. This additional process of polymerization which occurs in thermosetting variety does not occur in thermoplastic variety. Thermoplastic variety forms the final product without undergoing further reaction with other chemicals within its formula.
There are many different polymers from which this coating product can be made from. Some of them include straight epoxy, acrylics, polyester-epoxy, polyester, and polyurethane. Polyester epoxy is sometimes referred to as hybrid epoxy. Powder ingredients are combined in a mixer before being transferred into an extruder for heating. When extrusion is finished, the mixture is turned into a flat substance by rolling it out. Time is allowed for the rolled substance to cool before breaking it into small particles.
The application process involves, pre-treating the surface, dust application, and finally the curing process. Pre-treatment involves cleaning the surface by removing any forms of dirt and debris that would affect proper bonding between the surface and the dust. Normally sandblasting is a major cleaning method used. Application involves the use of spray guns to apply the dust onto the substrate while curing involves enhancing the bond formed using heat.
Curing increases the durability of the coating because it improves the formed bond. Specific machines and/or rooms are used for curing. The curing machine must be set at a particular temperature. The quality of the finish can be affected greatly if the temperature is not maintained within the required range.
