Why powder coating is a better choice than standard paint
Powder coating Toronto is a more economical choice because it average transfer efficiency is 60 to 70% compared to the transfer efficiency of standard paint at 30 to 35%. Overspray can be collected and reused so there is virtually no wastage in the process. Approximately 50% of liquid paint is lost to evaporation and there is no possibility of reclaiming overspray. Another reason why powder coating is a better choice is safety because the product does not emit harmful volatile organic compounds (VOC’s) that are unsafe to humans and the environment. The fact that powder coating is VOC-free is actually its selling point. Regardless of the way that powder coating is applied, the resin will bind with the substrate and provide the weather-resistance and durability necessary for metal structures and equipment.
Why powder coating is a better choice than anodizing
Anodizing is another finishing technology that is often compared to powdercoating. Anodizing provides superior surface finish that is extremely abrasion-resistant but it only offers a few color options. Anodizing has a big market in North America because of its cost however; it is a poor choice if the environment is considered. Anodizing has high energy and water usage and the waste it generates during the anodizing process does not make it a better option.
Aside from its environmental advantages, Toronto is the choice of many manufacturers because of the uniform surface finish with no apparent sags or bubbles. Not only does powder coating greatly improves the aesthetics of a product, it also provides impact resistance, corrosion resistance and flexibility. It successfully addresses the requirements of consumers in superior quality of finish and durability.
The process of powder coating
The first step in powdercoating Toronto is the preparation of the surface through blasting. The performance of powder coating is significantly affected by its ability to adhere to the surface and this is the reason why surfaces are subjected to abrasive blast cleaning to remove all traces of residual mill scale and other surface contaminants. The application of pre-treatment chemical on the surface is optional and it is based on the requirements of the client whether further protection is necessary on the surface. After abrasive blasting, the surface of the workpiece is cleaned thoroughly with water and allowed to dry completely, Powder coating is applied through a preferred method after which the part is cured in an oven. Convection ovens are typically used for curing but an alternative is infrared curing that result into better powder flow and minimal dirt defects.
