TGIC-Based Polyester Resins: Properties and Applications
TGIC (Triglycidyl Isocyanurate)-based polyester resins are thermosetting powder coatings known for durability, weather resistance, and chemical stability. Below is a structured overview:
| Property | Specification |
|---|---|
| Curing Agent | Triglycidyl Isocyanurate (TGIC) |
| Resin Type | Carboxyl-functional polyester |
| Curing Mechanism | Epoxy-carboxyl reaction (thermosetting) |
| Curing Temperature | 180–200°C (356–392°F) |
| Curing Time | 10–20 minutes |
| Weather Resistance | Excellent (UV-resistant, >10 years outdoor durability) |
| Chemical Resistance | High (resists acids, alkalis, solvents) |
| Mechanical Properties | Hardness: 2H–3H (pencil); Flexibility: ≤2 mm (cone bend test) |
| Feature | TGIC-Based Polyester | Non-TGIC (e.g., HAA-Based) |
|---|---|---|
| Weather Resistance | Superior | Moderate |
| Curing Efficiency | Fast | Slower |
| Film Flexibility | Excellent | Good |
| Regulatory Status | Restricted (REACH) | Eco-friendly |
| Industry | Use Cases |
|---|---|
| Architectural | Window frames, fencing, aluminum profiles |
| Automotive | Wheels, trim parts, underbody coatings |
| General Industry | Appliances, machinery, outdoor furniture |
| Functional Coatings | Anti-corrosion pipelines, electrical enclosures |
| Aspect | Details |
|---|---|
| Health Concerns | TGIC is a suspected mutagen (handle with PPE) |
| Regulations | Restricted in EU (REACH); alternatives (e.g., HAA) preferred in eco-sensitive markets |
| Storage | Dry, cool conditions; shelf life: 12 months |
| Resin Type | TGIC-Based Polyester | Epoxy Resins | Hybrid (Epoxy-Polyester) |
|---|---|---|---|
| UV Resistance | Excellent | Poor | Moderate |
| Adhesion | Good | Excellent | Good |
| Cost | Moderate | Low | Moderate |
TGIC-based polyester resins offer unmatched outdoor durability for powder coatings but face regulatory constraints. Alternatives like HAA-based systems are gaining traction for eco-compliance.
