Western Trailer installs pre-paint
blast booth to enhance paint finish on trailers 2012.
Along with the 75' long blast booth the company has developed an
entire new painting protocol that brings state of the art metal finishing to
our exposed metal parts.
Here is the process: Check out our Photo page for the pictures that go along with each numbered step below.
1. Surface Preparation
Steel undercarriage, side rails and other exposed steel components
are exposed to a thorough round of compressed air blast using 80 grit steel
bits in our 75' long SAFE Systems Inc, blast building. This is the same system used by aircraft, boat and rail car
manufacturers. By blasting the metal bits into the steel it creates a
profile on the steel that allows the paint to better adhere to the surface by creating a
mechanical bond and minimizes the potential for rust creep if a chip does
2. Pre-primer surface washing
Exposed parts are washed at between 180 and 200 degrees with
Dubois Securestream FRP Iron Phosphate, rinsed and then sealed with SpectraLink
Sealer. This removes any and all
foreign material (oil etc.). Iron
Phosphatizing is the chemical process that converts the surface area of iron or
steel to a matrix of millions of tiny metal iron phosphate molecules creating a
chemical bond. This coating is
considered a conversion coating in that it is converted to a new substance that
is not longer "Free" metal. "Free" metal is more reactive and more susceptible to corrosion.
Only after the steel has been blasted, bathed in Iron Phosphate
and sealed with Dubois Link Technology SpectraLink nonchrome sealant affixed to
the metal. Surface areas are covered
with LV260 Epoxy Primer at a thickness of approximately 4 to 5 mills.
4. Final Finish
The final finish is a polyurethane U-TECH 3.5 System High Solids
low VOC 2K. This Polyester formulation
provides high chemical resistance, flexibility and toughness.
The finishes are dried using an infrared drying process that heats
the surface metal and cures the paint from this point outward. This assures absorption of the primer and
finish base and allows the direction of the heat where it is needed most.
Because flat surfaces absorb energy best the more complex areas can have
infrared directed toward these parts of the under-carriage.
Our paint process is regularly and thoroughly tested by an outside
laboratory using Gravelmeter SAE J440 GT-28, Adhesion ASTM D3359, Humidity ASTM
CEMS GT-5B, Salt Spray 500 hours CEMS-GT-7D. Western Trailers are finished to provide a quality appearance with
significantly reduced risk of rust or flaking.
When you buy a Western you are buying superior paint work driven from
the early stages of the metal preparation to the final coat that combine to
provide the state of the art in corrosion protection.
