What Is Powder Coating?
The powder coating process uses a solvent free dry mix of
plastic resins, pigments and fillers that melt and fuse
together when heated. The solid particles of coating are
electro statically charged in a spray gun and carried by low
velocity air to the surface of the piece to be coated. The
electrostatic charge holds the powder particles in place
while the part is cured in a 400-degree oven. The heat of
the oven causes a chemical reaction to occur and the powder
to cure, creating a highly durable finish.
The Benefits of Powder Coating
Environmentally Friendly Process Powder coating is an
environmentally friendly process unlike solvent-based wet
paint systems. With EPA regulations growing ever stricter,
powder coating is fast becoming the technology of choice.
Since the powder coating process does not use solvents in
any way, VOC emission problems are eliminated.
Powder Coatings resist cracking and peeling and are
extremely abrasion, corrosion and chemical resistant. The
performance characteristics of powder coating match or
exceed the characteristics achieved from conventional
With powder coating, your imagination is your only limit.
Apply a textured coating to the handle of an existing
product to give it a more reliable grip. Provide UV coating
for outdoor furniture to make your product stand the heat of
summer. The options and applications for powder coating are
Expand your inventory by providing your current products in
color or with texture. Powder coating is available in almost
any color available which can easily enhance the appearance
of your current line, whether it be metallic vent fan covers
or stamped metal toy cars. Don't fall behind the
competition, provide superior products that look superior.
Sandblasting ‘etches’ the surface of the metal, creating a
solid mechanical bond adhesion during the curing process. It
also cleanses the metal. We use very fine angular aluminum
oxide media because it gives the best results for powder
coating adhesion. Picture in your mind that the type of etch
this media leaves behind would be similar to ‘sharp peaks
(hills) and valleys’.
Glass beading uses a round glass media that ‘pocks’ the
surface other than impinging the surface. This kind of media
is used more for aesthetic purposes than functional uses.
Glass bead media does not provide the best ‘anchor tooth’
for best powder coating adhesion. Glass beading a surface
(especially aluminum) reflects the light to your eyes
better, and makes metal appear whiter or brighter.
