How powder coating works

The basic process of powder coating is straightforward. Here’s a step-by-step guide to powder coating and protecting metal.

1.Blast It – Sandblasting is the best way to prep a metal surface in need of restoration.  It removes dirt, grime, rust, corrosion.  It also removes existing painted or powder coated finishes.  All types of metal can be blasted such as alloys, aluminum, steel, iron, etc. Sometimes coaters will use a chemical strip process prior to abrasive blasting to keep the blast time down to a minimum.  If you have a new metal project you can sometimes by-pass this step.  Your powder coater will be able to make this determination.  The point of blasting is to remove any mil-scale rust and rough up the surface prior to coating.

2.Prep It – Prepping consists of applying a metal prep chemical solution to neutralize surface impurities, cleaning off any lingering debris and prevent rust and corrosion.  Depending on the type of metal there are several kinds of solutions your powder coater can use to enhance the surface before coating.  If this is a concern for you make sure to ask your powder coater about what they will be using;  this is a step that should not be missed.[/et_pb_text][et_pb_text admin_label=”MPW Blog Form Mobile” _builder_version=”3.29.3″ global_module=”12659″ saved_tabs=”all”]

There are outdoor rated and interior only rated colors and powders.  Some powders require clear coats which could add to an increase in costs.  Here’s more on powder types with this post.  Be sure to ask your coater which is best for your project.

 

4.Cure It – The cure times for metal can range depending on how long it takes the oven to get to temp and the size of the oven. Typically degrees ranging from 250(low cure) to 400 are required for the powder to heat up enough to bond.  Once the right temp is achieved it takes 15-30 minutes for your metal part to achieve this state.  A coater’s oven should evenly displace the heat so that your part is heated throughout for the curing process to be done correctly.
