Our Powder Coating Process

We Have You Covered from Start to Finish

Our personalized services extend beyond the application of superior powder coating finishes. At Keystone Koating, we have a comprehensive powder coating process that includes optional services to achieve your ideal results. Our powder coating process covers everything from start to finish, including preparation for coating, blasting and powder coating, and packaging and shipping for your convenience.

Blasting

Blasting is a cost-effective technique for preparing surfaces for a smooth finish and strong bond. We use professional abrasives blasting to remove anything that could interfere with the powder coating process, including rust, oil, welding ash, laser scale, mill scale, and more. Removing these residues to create an even surface helps prevent cracking, bubbling and moisture buildup in your finished product. Blasting also roughens metal surfaces at the micro level to promote a strong bond with primers and powders.

Depending on your needs, we offer two abrasives to choose from:

  • 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.

Masking

Masking is a vital step if your products have threads, holes, studs, machined parts or other areas you want to keep clear of powder during coating. At Keystone Koating, we provide precision masking services you can add to your powder coating procedure. Our dedicated masking teams use advanced products to protect even the smallest areas and apply them using precise, time-saving techniques to maintain high finish quality and fast turnaround times.

8 Stage Pretreatment

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 Pretreatment 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.

Primer

Primers provide a layer of protection for your products and help strengthen the bond with your powder coat. The powder coating primer process adds enhanced resistance to corrosion and is the perfect addition for metal surfaces destined for outdoor applications. With the right selection, you can prevent rust and oxidation even in areas with severe weather, coastal breezes, excessive moisture and high humidity.
 
Our priming system provides an even coat while controlling overspray to limit costs and reduce the impact on the environment. When it comes to quality, our primers are the most effective on the market and, for exterior applications, will extend the life of your coating up to four times longer than surfaces lacking a primer coat.

Coating

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.

Our Lititz plant is home to two batch systems and two automated coating lines:

  • Automated line: Maximum, with primer: 36″W x 72″H x 240″L, weight 1,100 lbs.
  • Automated Line: Maximum, without primer: 24″W x 58″H x 72″L, weight 300 lbs.
  • Batch systems: Maximum with primer: 42″W x 72″H x 192″L, weight 800 lbs.

Our Mifflintown location has one batch system and one automated line:

  • Automated line: Maximum, with primer: 36″W x 72″H x 192″L, weight 1,100 lbs.
  • Batch system: Maximum with primer: 42″W x 74″H x 204″L, weight 800 lbs.

Curing

Our powder coating curing process is the result of over 30 years of continued innovation and development, and our industrial ovens offer precision control over the curing process. We use our expertise to set your order to cure at the precise temperature and time for effective and efficient curing. To ensure an even cure, we routinely check and log the temperature for accuracy and consistency throughout the process.
 
Cure time and temperature will vary depending on the powder, thickness and other specifications for your order. Any miscalculation can have a significant impact on the outcome of your finish. In most cases, the entire curing process is complete in under 25 minutes, with average baking temperatures ranging between 325 degrees and 400 degrees F.

All of our QC inspectors have the training and skill to identify any rare instances where a product requires our additional attention. For all orders, our QC process includes an inspection of powder coat adhesion, cure, millage (thickness) and the overall visual appearance. If you would like us to perform additional inspections, we are happy to accommodate your request.
