Most competitors are using a general-purpose Super Durable or Standard Polyester TGIC powder coating. DSI uses a Custom Blended Premium Pigmented Super Durable Polyester TGIC powder coating. DSI also provides third-party test results documenting our processes are Verified AAMA 2604 and AAMA 2605 Compliant. This needs to be completed every 18 months. Every 12 months, the Powder Coating Institute audits the powder coating process based on the PCI4000 A2 and A3 164-point criteria. Most competitors rely on their powder coating suppliers to provide testing documentation instead of an independent third party lab approved by AAMA. Competitors may only complete this testing once every 5-10 years.
