|---|---|
| Definition | Polyester resins cured using Hydroxyalkyl Amide (HAA) crosslinkers as an alternative to traditional TGIC (Triglycidyl Isocyanurate). |
| Composition | – Base resin: Carboxyl-functional polyester. – Curing agent: HAA (e.g., Primid® XL-552). – Additives: Pigments, flow agents, UV stabilizers. |
| Key Properties | – Excellent weather resistance (UV/gloss retention). – Low toxicity (non-TGIC, REACH-compliant). – Good mechanical strength and flexibility. |
| Advantages | – Eco-friendly (no hazardous byproducts). – Lower curing temperature (~160–200°C) vs. TGIC. – Suitable for thin-film coatings. |
| Limitations | – Slower curing than TGIC. – Sensitive to humidity during application. – Limited high-temperature resistance (<120°C). |
| Applications | – Powder coatings for outdoor use (architecture, automotive). – Appliances (e.g., refrigerators, washing machines). – General industrial metal coatings. |
| Property | HAA-Based | TGIC-Based |
|---|---|---|
| Curing Agent | Hydroxyalkyl Amide | Triglycidyl Isocyanurate |
| Toxicity | Non-toxic, REACH-compliant | Hazardous (regulated) |
| Curing Temperature | 160–200°C | 180–220°C |
| Weather Resistance | Excellent (long-term gloss) | Very Good |
| Film Thickness | Optimal for thin films | Thicker films possible |
Growth Drivers: Rising demand for sustainable powder coatings in Europe and North America (TGIC phase-out).
Innovations: Hybrid systems combining HAA with acrylics for enhanced durability.
Regulations: Preferred for compliance with EU REACH and U.S. EPA standards.
