What is a powder coater?

Powder Coating is a dry finishing process created by an electric charge that causes a dry powder to fuse to the surface of the metal. This is then baked in a curing oven to achieve a smooth coating. It is usually used to create a hard finish that is tougher than conventional paint.

What is pretreatment for powder coating?

Pretreatment is the base for powder coating. It is said that you can not make a good coating work with poor pretreatment. Hence utmost care should be taken to ensure proper pretreatment is applied before powder coating. Proper pretreatment means application of the right process and proper maintenance of the chemicals.

What is liquid coating?

Liquid coating is a wet paint process that has been used on various substrates for hundreds of years. Liquid coatings can be applied electrostatically or with a conventional spray gun and can be air dried or cured in a heated environment which results in a more durable finish than air-dried parts.

Can you turn powder coat into paint?

Normally, powder coating has a slick surface which does not allow paint to stick. Sanding it down carefully will enable you to paint on it effectively. Wipe down the area you will be painting with an appropriate solvent cleaner.

Will a heat gun remove powder coating?

Using a heat system to remove powder coating can offer a fast and efficient way to remove powder coating and reduce potential environmental disposal issues that are a part of using chemical strippers. Additionally using heat can be one of the fastest ways to remove significant volumes of powder coating.

What temperature can powder coating withstand?

The most common powder coatings can withstand temperatures between ambient to 200°F, although most are on the lower end of the spectrum. These general powders will do the trick for most typical applications, but may be susceptible to significant color change and other issues once you start pushing that 200°F+ range.

What is the difference between anodized and powder coated?

Anodizing is harder than powder coated surfaces. Anodizing gives aluminum a deeper, richer metallic appearance than is possible with powder coatings. This is because an anodized coating is translucent, and one can see the base metal underneath the coating. This translucence may contribute to color variation problems.

What is pretreatment process?

Pretreatment is a must for removing unwanted materials from textiles. It is a series of cleaning operations in which all the impurities that cause adverse effects in dyeing and printing are removed. The pretreatment process differs according to the shade of the dyed material and depends on the buyer’s requirement.

How do you prepare aluminum for powder coating?

The key to preparing the substrate is removing the oxide layer, providing a pure metal surface for the coating to which to bond. Surface Cleaning— Aluminum surfaces must be clean and free of oil and grease before they are powder coated.
