Powder Coating Process
Our Powder Coating Process uses the Sherwin Williams Powdura OneCure Powder System to deliver a durable, high-quality finish. Sherwin Williams Powdura OneCure is a single-cure, dry-on-dry primer and topcoat system that combines exceptional performance in extreme conditions with superior color and gloss retention.
We follow a 6-step process to guarantee that our custom trailer powder coating is the top choice for protecting your trailer.
Step 1: Each trailer undergoes steel shot blasting to remove rust and mill scale, creating an ideal anchor profile for optimal adhesion of the Zinc Epoxy Primer Powder.
Step 2: We then run the trailers through a two-stage automatic pretreatment cleaning process.
Stage 1-Phosphate Metal Pretreatment Wash
Removes foreign contaminants, inhibits rust, and improves paint adhesion.Stage 2-Final Rinse
Rinses the metal to enhance adhesion to the blasted surface and ensure a stronger bond with the powder coating.
Step 3: After the pretreatment wash, trailers enter a forced air dry-off oven to eliminate residual moisture and ensure the metal is fully dry before powder coating.
Step 4: A single-cure, dry-on-dry Zinc Epoxy OneCure Primer is applied to the entire trailer frame, ensuring full coverage for optimal adhesion and corrosion protection.
Step 5: In this step, we apply a high-gloss OneCure powder in all colors, using Sherwin Williams’ ultra-durable primer and topcoat for superior color retention and UV protection against weathering.
Step 6: In the final step, trailers are cured in an oven at over 425 degrees, cross-linking the Powdura OneCure zinc primer and topcoat to create a durable, corrosion- and chip-resistant finish that extends the life of your trailer.
