Powder Coating

Powder coating is the fastest growing finishing technology in North America. Its profound rate is due to its economic and environmental advantages over liquid paint and at the same time providing a superior finish.

There are two segments to the powder coating business. 3P Industries serves both industrial segment and the custom coating segments of the market. We have the equipment and technology to tackle the largest of jobs from industry. We are also able to accommodate the smallest of jobs for the individual that need our product and service.

The process of powder coating can be divided into three separate stages, Cleaning, Coating, and Curing.

Cleaning:

Cleaning is the first step in powder coating and is the removal of all organic and inorganic soils from the product to be coated. Examples of INORGANIC SOILS would be rust, smut, heat scale, oxides, stains, and loose particulate matter. These items would normally be removed by media blasting and/or chemical process. Examples of ORGANIC SOILS would be mill oils, oily or wax films, rust inhibitors, coolants, lubricants, die release and drawing compounds.

The main burden of the cleaning process is to remove the organic soils common to most metallic substrates. The most common form of cleaning chemistries from organic soils is water based chemical formulations, combining surfactant, detergents, alkaline builders, and sequestering agents. Cleaning the products to be coated is normally completed in an industrial washer combining heat and high pressure.

Coating and Curing:

The dry pigmented powder, if held in your hand, looks and feels like colored Baby Powder. It is also just as safe. Basically because it is free of the hazardous volatile organic compounds (VOC) contained in liquid paints. The powder that is sprayed is captured and recycled creating very little waste.

Today, powder coatings are available that result in a highly durable finish in a variety of colors, glosses and textures. New formulations in powders have made it possible to achieve innovative finishes that are above and beyond liquid paints. Powder coating’s strong resistance to extreme temperature, chemicals, UV rays, abrasion, cracking or chipping has made it a popular finish with automotive and motorcycle parts as well as outdoor furniture and exercise equipment, to name a few. Powder coating is also an excellent choice for refinishing and restoration projects.

1. What about Colors?

Powders are available in almost every color and shade imaginable. Custom colors can be formulated to meet almost any need. 3P stocks many different colors and others are no more than a phone call away. There is an additional charge for special colors in small quantities.

2. What can you paint?

Almost any clean metal surface including aluminum, cold rolled steel, hot rolled steel, hot rolled steel pickle and oil, cast iron, zinc casting, aluminum casting, copper and paintlock-electro galvanized to name a few.

3. Does the part have to be clean?

Absolutely, however, 3P has the equipment and/or the resources to clean most products or projects. The conveyerized washer will handle most projects. We can media blast or otherwise clean your rust or scale problems.

4. Can powder be applied to outdoor products?

Absolutely. We have the powders on hand that are formulated for outdoor use and have UV resistant properties.

5. Is powder coating safe for consumers such as children?

YES. Powder coating is used in children’s toys and furniture sold every day. It has the distinction of being one of the most environmentally and consumer friendly products on the market today.

6. What if there is something on the product that is not metal?

The coated parts are cured in an oven at up to 450 degrees Fahrenheit, for up to 30 minutes or more. Any part of your product that cannot withstand this time and temperature must be removed before coating.

7. How much does powder coating cost?

  • Industry – we will need a product and/or a sample of what you need us to coat. We will first help you select the powder product you need and then will issue a formal written quote based on your requirements.
  • Consumers – a few items we will be able to quote over the phone, most we will need to see the product to ascertain cleaning and coating requirements. More question? We’ve got more answers. Just ask.
