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.
Thermosets and thermoplastics are the two primary forms of powder coats. Cross-linkers are integrated into the formulations of thermosetting type. Polymerization reaction takes place within chemicals in thermorsets to improve them. Polymerization only takes place in thermosetting variety because in thermoplastic variety, it does not happen. Thermoplastic variety forms the final product without polymerization.
The dust is manufactured from a number of polymers including acrylics, polyester-epoxy, polyurethane, straight epoxy, and polyester. Polyester epoxy is also commonly known as hybrid epoxy. The production process includes mixing powder ingredients in a mixer before heating inside an extruder. After extrusion, the mixture is rolled into a flat substance, which is then cooled before being broken 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.
