Painting is becoming outdated because it wears out fast, emits volatile organic compounds, and it is at times expensive.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.
Powder coating has several advantages over traditional liquid painting and other methods that previously dominated the market. The first advantage is that handling powder coat is much easier and convenient. Since the substance remains in dry form, it does not easily stick on clothes or other unintended surfaces during application. There is also no need for a solvent to keep it in suspension form.
Application involves electrostatic means through the use of a spray gun. A positive charge is imparted into the particles by the gun during emission. With the positive charge, the particles are attracted to the substrate which is normally negatively charged. The two opposite charges causes a strong bond which is enhanced through heat curing. The resultant finish caused by curing is harder and tougher than that resulting from conventional paints.
This coating method is applied on a wide range of surfaces and products including aluminum extrusions, automobile parts, bicycle parts, drum hardware, and household appliances among others. The surfaces of application may be of any kind including metals, wood, plastics, and metal alloys. With improved technology in the modern world, application has been extended to other materials like medium density fiberboard. In future, more surfaces will be able to be coated with this product.
Powder coats are made into two main forms, that is, thermosets and thermoplastics. A cross-linker is included in the formula of thermosetting varieties. Thermorsets have improved performance because they react with other chemicals within them to result into a polymerization reaction. Polymerization is an additional process in thermosetting variety only because it does not exist in thermoplastic variety. The final product is formed in thermoplastic variety without the intermediate polymerization process.
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 is important for enhancing the bond hence is responsible for ensuring maximum life. Curing is done within a curing room under specific temperatures. Exceeding or working below the required temperature may affect the final finish formed.
