As the name implies, powder coating in Ontario involves the application of an even coat of paint which is electrically-charged to make it stick to the part that is grounded. It may sound pretty amazing but how does it differ from the traditional spray painting? The key difference is that powder paint does not require a liquid carrier or solvent which evaporates when the paint dries. Thus, it results in zero-emission of a toxic substance into the air while allowing you to apply a thicker coat since there will be no excess paint sagging or running off the part surface.
Another major benefit is that you can choose from a variety of powder coat colours available for you to consider. The neatness of the layer of the coating is attributed to the electrically-charged particles that will always try to look for the uncovered surface area on the part, which produces an even coating. When it comes to the types of powder coating in Ontario, there are plenty to choose from but they can be categorized into two major ones, the thermoplastics and thermosets. Thermoplastics are formed into the final coats at the time of the baking process while the thermosets involve a cross-linker combined with the formula that reacts with other chemicals during the polymerization process.
Powder coating in Ontario is done following three major steps. The first one is the preparation in which various chemicals and mechanical techniques are utilized to thoroughly clean the parts to be coated. Any kind of contaminants will be removed such as soil, oils, greases, and other foreign particles so that the paint will fully adhere to the surface during the coating. Once the surface has been cleaned, the next step is to spray the powder coating to the grounded object that has to be painted using an electrostatic gun. The last step is the curing wherein the applied coat will be subjected to elevated temperature to let it merge and bond fully onto the surface.
