Our Powder Coating Process
- Steel Grit: Steel grit is used for steel materials in thickness 11 gauge and higher, with a maximum dimension of 48″W, 17″H and 300″L.
- Aluminum Oxide: Aluminum oxide is suitable for any metal 16 gauge or thicker, and we can process items up to 72″W, 72″H and 228″L.
Pretreatment cleans and prepares your surfaces to ensure your primers and powders make an effective bond with your metal surfaces. Pretreatment is a powder coating cleaning process, designed to prepare surfaces through the application of various treatments. Together, these treatments make sure your surfaces are free from residue and enhances them for a better appearance and lasting durability.
At Keystone Koating, we offer a proprietary 8 Stage Preatreatment process to ensure your metal surfaces are clear of any contaminants and optimized for powder coating. To clean your products, we use a wide range of solvents and techniques, rinse at multiple stages and immediately dry them to prevent corrosion. We offer several conversion coatings for greater adherence with primers and powders.
We combine our industry expertise with the latest technology to deliver superior adhesion for your selected powder coat. We deliver a positive electrostatic charge to your powders before loading them into our spraying system and ground your metal surfaces for an opposite charge. When sprayed, the charged powders attract to your products and cling to them, remaining tight against the surface until bonding is complete.
We have two locations to handle a wide range of requests and are capable of processing significant quantities with fast turnaround and delivery. Each site offers coating through batch systems and automated powder coating lines.
