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.
When compared to other coating methods such as use of conventional paints, powder coating has way too many advantages. The first benefits of powder coat are that it is clean and convenient to handle. This is because it does not stick on clothes and other surfaces because it remains in dry form. Solvents for maintaining the suspension state are also not necessary.
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.
Application involves, surface pre-treatment, actual application, and curing as the final step. Pre-treatment targets at removing dirt and debris that impedes a strong bond from forming between the dust and the substrate. Sandblasting is a common method used for cleaning and pre-treating surfaces. Spray guns are used to smear the substrate with the dust while curing by heat enhances the bond formed.
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.
