TGIC-Based Polyester Powder Coatings: Overview
| Category | Details |
|---|---|
| Definition | Thermosetting powder coatings using Triglycidyl Isocyanurate (TGIC) as a crosslinker for carboxyl-functional polyester resins. |
| Composition | – Base resin: Carboxyl-functional polyester. – Curing agent: TGIC (typically 5–10% by weight). – Additives: Pigments, flow modifiers, UV stabilizers. |
| Key Properties | – Excellent weather resistance (UV, humidity, corrosion). – High mechanical strength and impact resistance. – Good chemical resistance (acids, alkalis). |
| Advantages | – Fast curing (10–15 mins at 180–200°C). – Superior edge coverage and film thickness control. – Long-term outdoor durability (15+ years). |
| Limitations | – TGIC is toxic (mutagenic, regulated under REACH). – Higher curing temperature than HAA alternatives. – Limited flexibility in thin films. |
| Applications | – Architectural coatings (window frames, facades). – Automotive parts (wheels, trim). – Outdoor furniture, electrical enclosures. |
Comparison with HAA-Based Polyester Coatings
| Property | TGIC-Based | HAA-Based |
|---|---|---|
| Curing Agent | Triglycidyl Isocyanurate (TGIC) | Hydroxyalkyl Amide (HAA) |
| Toxicity | Hazardous (regulated) | Non-toxic, eco-friendly |
| Curing Temperature | 180–220°C | 160–200°C |
| Weather Resistance | Excellent (extreme climates) | Very Good (moderate climates) |
| Film Thickness | 60–120 μm (versatile) | 30–80 μm (thin films preferred) |
Market & Regulations
Market Status: Dominant in industrial applications but declining in Europe due to TGIC restrictions (REACH Annex XVII).
Alternatives: HAA and glycidyl-based systems (e.g., PT910) replacing TGIC.
Regions in Use: Still prevalent in Asia and niche high-performance applications.
