Wheels Doctor Powder Coating: superior scratch, impact, and chemical resistance

Wheels Doctor Powder Coating: superior scratch, impact, and chemical resistance Powder coating paint is a dry finishing process that has become extremely popular since its introduction in North America over in the 1960s. Unlike conventional liquid paint powder coating is typically applied electrostatically and then cured under heat or with ultraviolet light.

Representing over 15% of the total industrial finishing market, the powder is used on a wide array of products thanks to more and more companies specifying powder coatings for a high-quality, durable finish, allowing for maximized production, improved efficiencies, and simplified environmental compliance.  

Limitless range of colors and textures, plus excellent performance properties.

The powder may be a thermoplastic or a thermoset polymer  tougher than conventional paint and Because powder coating does not have a liquid carrier it can produce thicker coatings than conventional liquid coatings without running or sagging, powder coating technology like UV curable powder coatings allow for other materials such as plastics, composites, carbon fiber, and MDF (medium-density fibreboard) to be powder coated due to the minimum heat and oven dwell time required to process these components

Powder coating is mainly used for coating metals, such as household appliances, aluminum extrusions, drum hardware, automobiles, and bicycle frames

A process with incredible results thanks to our team of professionals

To understand why powder coating is superior to wet paint, it is important to first understand the application process. Powder coating consists of an electrostatic application of organic powder to metal parts that require coating for protection or decoration based on polymer resin systems, combined with curatives, pigments, leveling agents, flow modifiers, and other additives.  These ingredients are melt mixed, cooled, and ground into a uniform powder similar to baking flour

The powder coating process includes a pre-treatment, an application of powder, and its subjection to high temperature resulting in a continuous hard coating process.

The process begins with the pre-treatment, that is, the preparation of the substrate surface. In this, each part is cleaned, removing grease, dirt, and anything else that may interfere with the coating. Such preparation includes an abrasive, mechanical, or chemical cleaning, depending on where the surface of the metal to be treated is cleaned so that it adheres well with the powder during the subsequent curing process. Without a proper pre-treatment, the dust in certain parts will chip and corrode easily, that is its importance.

We consider the surface texture desirable or acceptable depending on the aesthetic and technical quality of the end product.

In addition, the best results are obtained when rust or pre-existing coatings are removed. After this phase, the object must be completely dry before the powder is applied. This can be accomplished using air-drying methods, or by hanging items on shelves. An oven is even used for this drying process, although the objects must be cooled before applying the powder. Regarding the level of freshness, this varies according to the desired coating thickness.

Once the part is completely dry, it is ready to be powder coated using fluidized bed or spray techniques. The powder is electrically charged as it is applied to the part, giving each particle a negative charge.

This electrostatic attraction is a key requirement of the process, as it helps the uniformity of the coating and the speed of its application. The result is a uniform layer of dry powder that adheres to the object. After the part is powder coated, it is transferred to a curing oven, in which the powdered gels flow and cure, thus generating a smooth product and a durable finish. In the curing process, a chemical crosslinking reaction takes place between the powder particles. It is at this point where the piece can be removed from the oven, cooled to room temperature, and prepared for release to the market.

Quality that lasts almost forever….forever stylish, forever coated.

Powder coating protects the roughest, toughest machinery as well as the household items you depend on daily.  It provides a more durable finish than liquid paints can offer, while still providing an attractive finish.  Powder-coated products are more resistant to diminished coating quality as a result of the impact, moisture, chemicals, ultraviolet light, and other extreme weather conditions. In turn, this reduces the risk of scratches, chipping, abrasions, corrosion, fading, and other wear issues. Plus being durable, powder coating is an attractive choice due to its environmental advantages.

Colorful exteriors aren’t just decorative they are functional barriers that prevent corrosion but not only that also it is an eco-friendly and safer option.

As we know, wet paint is flammable, carcinogenic, and full of volatile organic compounds. Such chemicals can be dangerous to personnel if not handled properly, instead, powder coatings are generally VOC-free materials and do not contain solvents, meaning they do not involve potentially harmful chemicals typically found in methods. wet spray. Although powder coating materials can burn in a very small concentration of dust and air, their lack of solvents or VOCs does not pose health hazards, or short-term and long-term fire threats. 

Regarding the environment because powder coatings do not contain solvents they are more environmentally friendly than their wet paint equivalents. In addition, powder coat is a clean process as the excess powder can be recovered and reused in a hopper to be recirculated through the system, with negligible waste. It should be added that most powder paint materials are considered non-hazardous materials, so they can be safely disposed of.

We provide the best uniform coating with a variety of colors and possible custom patterns

Our collection of standards colors that are available for dry powder coating. Although not extensive as liquid paint, powder coating presents a wide selection of colors to choose from. The cost of powder coating is higher than a simple spray can bomb, but once you use it, you’ll find it hard to go back.

Durability, professional look, and a sheer number of color choices.

Deciding a winner for the great coating versus wet paint and plating battle for your products can be a difficult decision. But, you could consult our experts who can help you consider all of the possibilities with special detail to your needs.
