Powder Coating

Powder coating is a dry finishing process using sprayers to apply finely ground paint particles to a substrate using electrostatic charge. Powder adheres to the substrate by electrostatic attraction until melted and fused into a uniform coating in a curing oven.

FAQ: Powder Coating

What is powder coating?

Powder coating is a dry finishing process used to apply a dry coating material. The coating material is made up of finely ground particles of resin and pigment for color, along with other additives for specific functions such as gloss or hardness. The dry powder coating is delivered to a spray gun tip that is fitted with an electrode to provide an electrostatic charge to the powder as it passes through a charged area at the gun tip. The charged powder particles are attracted to a grounded part and are held there by electrostatic attraction until melted and fused into a uniform coating in a curing oven.

What powder coating is best for my job?

“We must begin by explaining the basic chemistries available in the market today. We’ll cover the basic advantages and key disadvantages that each one of these possesses. Moving forward, some key groupings of exposure must be understood. Examples include accelerated weathering, salt fog and moisture, chemical resistance, flexibility for post-cure bending, durability (both physical and exposure-related) and others.

How to powder coat plastic parts?

The number of plastic parts painted and coated is growing—and in a practically unlimited scope of diversity. In order to avoid painting defects and optimize quality, it pays to carefully scrutinize the entire process. A number of challenges need to be met to this end. These include optimized quality along with strong economic efficiency and sustainability. This is further augmented by ever smaller lot quantities and an increasing variety of colors.

What coating system gives the best long-term coating performance?

If asked what gives the best protection against corrosion and UV exposure, it would be electrocoat and a super durable powder coating. Whether you have a zirconium pretreatment system or zinc phosphate pretreatment system, either will give very good corrosion performance. The super durable powder coating will give the best weathering performance, meaning color fade and gloss retention in sun-exposed areas.

What is the cost of powder coating?

Calculating the coating cost of a particular part starts with gathering the variables associated with that part. What is the part size, how many of them can you fit into your coating process per hour and how much surface area will be coated?

This process data is used to determine the parts per hour so that the hourly costs can be broken down into a cost per part. The number of pieces per rack, racking centers and line speed can be used to determine the production volume per hour at 100-percent efficiency. This number should be adjusted to compensate for breaks or other factors that reduce the line efficiency.
