About Us

Sun Polymers started in 1994 as a small plant in Fort Wayne, Indiana with two small reactors. Today we are a subsidiary of Taiwan-based Chansieh Enterprises.

We seek to provide polyester resin to powder coating manufacturers in a manner that is:

  • Wide ranging
  • Consistent in quality
  • Environmentally friendly

We recently added a solid acrylic resins product line that incorporates bead technology which can be used in the following applications:

  • Inks
  • Paints
  • Adhesives
  • Coating


Different types of polyester resin bring different benefits to the table. We offer polyester resins in a broad range of classes. We can provide a resin that’s suitable for your end-use application as well as your budget.

We Appreciate Our Customers

Unique Quality Assurance


Our quality control measures are head and shoulders above our competitors.

Most polyester resin manufacturers merely measure the physical properties of the resin without actually making a powder coating. We spray it out and cure it to actually test every batch. Our Q-PANEL paint testing means you get a consistent product for paints, plating, adhesives, sealants, and other coatings – every time.

It’s a fairly time intensive way to do QC, but it’s written into our iso-procedures. It’s what we do!

Environmental Stewardship


  • We strive for energy efficiency when we manufacture our products. We do that by operating our facility in a way that is as careful with environmental impact as possible.
  • We create a Total Quality Management environment, leading by example and sharing knowledge with our teams through training programs, controls, and procedures.
  • We source materials and services locally to minimize our carbon footprint.
  • We send zero waste to landfills. There are no solvents involved in our process.
  • We strive to conserve natural resources.
