Transparent Polyester Powder Coatings: Overview
| Category | Details |
|---|---|
| Definition | Clear, thermosetting powder coatings based on polyester resins that provide transparent protection and aesthetics |
| Composition | – Polyester resin (hydroxyl or carboxyl functional) – Crosslinkers (TGIC, HAA, or isocyanurates) – Flow agents, UV stabilizers, degassing additives |
| Key Properties | – Excellent optical clarity and gloss retention – Good UV resistance and weatherability – Chemical and abrasion resistance – Cures at 160-200°C in 10-15 minutes |
| Advantages | – Maintains substrate appearance (wood, metal effects) – Environmentally friendly (no VOCs) – Durable protective layer without color distortion |
| Limitations | – Requires extremely clean substrate surface – Sensitive to application parameters (film thickness 40-80μm ideal) – Higher cost than opaque coatings |
| Applications | – Metal furniture and decor – Automotive trim parts – Architectural aluminum profiles – Protective coating over metallic finishes |
