Powder coating is used to refer to a dry finishing method that is recently gaining a lot of popularity. This process utilizes powder materials which are made up of pigmented thermoplastic particles. Currently in the industrial finishing market, this process makes up 15 percent of the entire process. This process is growing at a very high rate such it is expected to grow even more. When in need of Powder Coating Langley BC should be visited.
This method is performed by electrostatically applying powders onto components that need to be coated. The application is done using a sprayer. Sprayers usually have various nozzles meant to achieve different effects in the application. The powders cling onto the component until they are fused during the curing process. Once cured, the powders melt and form a fine and smooth coat that can last for many years.
For powder coats to work well, they must be applied on surfaces that are clean so that the bond between the surface and the powders can be strong. Usually, surface cleaning and preparation is done using sandblasting. Sandblasting removes various kinds of materials such as paint and oil. Degreasing may also be necessary in order to prevent corrosion. There are also other methods that can be used for surface cleaning.
Materials used to make the powders include polyurethane, flouropolymer, thermoset and epoxy materials. There are different types of powders because of the different materials used to make them. When compared to thermoplastics, thermoset powders have a higher resistance level to heat. This is as a result of the cross-linked polymeric resins used to make them. Pressure or heat is needed for the resins to cure or set.
Fluoropolymer powders are the same in structure as thermoplastics and thermosets. The three categories of powders also have the same mechanical characteristics. However, fluoropolymers offer better resistance to bases, acids, and solvents. On the other hand, polyurethane powders offer better bonding with plastic surfaces. However, for the process of curing to be initiated, they require a catalyst, air evaporation or heat. Without these agents, curing cannot happen in polyurethane powders.
Very few finishing techniques compete with powder coating when it comes to durability. The roughest and toughest machinery used for industrial purposes are usually coated using this technique. Also, household products used every day are coated using this method. Among these household products are stoves, cutlery, equipment, utensils and others.
The benefits offered by this method include durability as well as beauty. The value and beauty of a surface increased significantly when applied with this finish. It is able to withstand corrosion by chemicals as well as effects by ultraviolet light, moisture and impact.
That level of resistance helps the coating to be able to resist scratches, chipping, corrosion, fading, and abrasions. Thus, quality is maintained for a long time. This is usually a good way of saving money and the need to worry about the finish after every few years.
