What is powder coating?

Powder coating is a different method of painting. It starts out as a liquid but is formulated and processed

differently. It is mixed, extruded and baked, then ground into a powder with the consistency of talcum powder.

Paint is comprised of pigments or dyes, binder and fillers suspended in solvent. As most people have spray bombed

or brushed a part or two, you understand that you have to wait for the solvent to evaporate for the paint to “dry”, usually

taking anywhere from minutes to days. With powder coating, the powder uses heat as a catalyst to cure the powder, usually

200 degrees C (390 degrees F).


With most powder finishes, once the part cools, you can assemble or install your parts immediately without fear of

damaging the finish. How does the powder stick to the part? Powder is applied by an electrostatic charge. Simply put, as the powder passes out of the nozzle of the gun it picks up a charge and is attracted to the grounded part. The thing with powder is if something goes wrong while coating a part, you can blow it off and start again. From there the part is put into the oven to cure.

Preparation


It is important to assess your needs at this point. Rust protection, decorative or a combination of both.
There are a few different ways to prepare the substrate to accept the coating.

Hot rolled steel has a mill scale which should be removed before coating. With older rusty material we sandblast to a clean grey finish. New parts are either degreased in a degreasing fluid or treated with phosphate to promote adhesion. Sometimes a combination of the two.

 

 

Colour choice


We have over 100 colours in stock to choose from. Because of the involved process in the manufacturing of the powder, we do not do “tinting” or altering of the colours we stock. We can do custom matches but this does add extra cost to the project.

 


Masking/taping


At VPC we understand that some surfaces need to be left free of powder. We use high temperature tape and plugs to protect

threads and bearing surfaces. Some surfaces are obvious like bearing and machined areas but if you need something protected you can mark it with a felt pen or tape. We will take pics to make sure we get it right.

 

 

Multiple colours on one part


Although it can be done, we tend to stay away from it. We may do it depending

on customer expectations.
