Product Feature: DM Coating System

While many trailer manufacturers choose powder coat and finish processes based solely on their material and operating costs, we designed this “Difference Maker” Powder Coating System to produce extraordinary trailer finishes.

The mantra is simple: Improve everything. Sacrifice nothing.

THE POWDER COAT PROCESS

We use a 6-step process to ensure our custom trailer powder coating is the best coating option for your trailer:

STEP 1

Each trailer frame is blasted with steel shot to remove the mil-scale and add an anchor profile for the primer to adhere to.

STEP 2

Then we wash them with a 5-stage wash process to clean the steel, add corrosion resistance, and balance pH.

  • Alkaline wash removes blast dust and oils
  • High-pressure rinse
  • Phosphate salt rinse inhibits rust and helps with paint adhesion
  • High-pressure rinse
  • Final sealing rinse is applied

All wash water is reverse osmosis (RO) purified to ensure consistency

STEP 3

Washed frames are promptly force-dried as they travel through our dry-off oven at 300 degrees. This prevents flash rusting and ensures that frames are primer-ready.

STEP 4

Ultra-corrosion-resistant Onecure Zinc Epoxy Primer powder coating is electrostatically applied to the entire trailer frame.

STEP 5

Smooth, high gloss, Onecure Technology Top Coat is electrostatically applied to the entire trailer frame.

STEP 6

The top coat is cured as the frame travels through our 165′ final-cure oven at 450 degrees. All steel surpasses 425 degrees to ensure complete curing of primer and top coat.
