There are many reasons that are putting conventional paints out of market. Some of them include emission of VOC compounds, low durability, and costliness. As such, other techniques of painting for aesthetic of protection reasons are coming up. Powder coating which entails application of free-flowing dry powder is one of the methods. When one requires experts of powder coating Los Angeles should be the location to prioritize.
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.
Various substrates and surfaces including household appliances, bicycle parts, aluminum extrusions, drum hardware, and automobile parts can be coated using this method. The surfaces coated could be made of different substances including plastic, metal alloy, metal, or wood. Medium density fiberboard, MDF can now also be coated as a result of better technology. With the current technology, more surfaces with be paintable through this process 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.
This coating product gets made from various polymers including polyurethane, straight epoxy, polyester, acrylics, and polyester-epoxy. Hybrid epoxy is the other common name for polyester epoxy. During production, powder ingredients are mixed inside a mixer and then heated in an extruder. Once the extrusion process is over, the mixture is flattened by rolling it out. The rolled substance can then be cooled and then broken down into small chips.
Pre-treatment, coat application, and curing are the three major steps involved in the application process. Surface pre-treatment is the first step and it is intended to clean the surface of dirt and other forms of debris. This enhances the strength of the resultant bond between the substrate and the dust. Surface cleaning and pre-treating are commonly done through sandblasting. The substrate is smeared with the dust using spray guns whereas heat curing finalizes the process.
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.
