Preparation
When preparing a substrate for coating, we need to
remember the most important thing. Proper
preparation! In order for the powder coating to
adhere properly to the substrate and have the
desired finish that you want, the preparation
process is the most important. The first step is to
remove all rust, mill and dirt.
Sandblasting
To remove the rust, mill and dirt we use a
mechanical method of sandblasting or tumble blasting
to do it. Larger items are sandblasted clean while
smaller items are put into a contained tumble
blaster where they are tumbled slowly while steel
shot cleans them up. In addition to cleaning the
substrate sandblasting ruffs up the surface just
enough for the coating to adhere to it properly but
not too much so the finish will be nice and smooth.
Final
Preparation
After the item has been
sandblasted and hung up for coating, it goes through
its final stages of preparation. First it is air
blown so it is dust and dirt free. Then we have an
optional automatic chemical rinse system to do one
final cleaning and also to promote adhesion. We also
offer a pre-coat sealer to give it the optimal
adhesion.
Primer Coat
(1st coat)
The primer coat or under
coat is the first coat of the coating cycle. We
operate a manual coating system to ensure that we
get in all the cracks and crevices so your product
won't rust. The primer is a new Zinc Rich Primer to
ensure top quality adhesion, maximum corrosion
protection and a long rust free life.
Top Coat (2nd
coat)
The top coat is applied
very much the same way the primer coat is applied.
Giving the product the look that you were expecting.
After it is fully coated the product is slid on a
rack into a large propane heated oven where it bakes
for 15 minutes at 400o Fahrenheit. When
it comes out of the oven it has the beautiful glossy
finish of a newly powder coated product.
Packaging
After the item has cooled off
fully it is then taken down from off the racks and
either packaged onto pallets, boxed up or
wrapped in foam and shrink wrapped. It is now ready
to be picked up or dropped off.
