HAA-Based Polyester Resins: Overview
| категорию | Подробнее |
|---|---|
| Определение | Polyester resins cured usingHydroxyalkyl Amide (HAA)crosslinkers as an alternative to traditional TGIC (Triglycidyl Isocyanurate). |
| Состав | –Базовая смола: Carboxyl-functional polyester. –Вулканизирующий агент: HAA (e.g., Primid® XL-552). –Добавки: Pigments, flow agents, UV stabilizers. |
| Свойства ключа | – Excellent weather resistance (UV/gloss retention). – Low toxicity (non-TGIC, REACH-compliant). – Good mechanical strength and flexibility. |
| Наши преимущества | – Eco-friendly (no hazardous byproducts). – Lower curing temperature (~160–200°C) vs. TGIC. – Suitable for thin-film coatings. |
| ограничения | – Slower curing than TGIC. – Sensitive to humidity during application. – Limited high-temperature resistance (<120°C). |
| Приложения | – Powder coatings for outdoor use (architecture, automotive). – Appliances (e.g., refrigerators, washing machines). – General industrial metal coatings. |
Comparison with TGIC-Based Polyester Resins
| Объект | HAA-Based | TGIC-Based |
|---|---|---|
| Вулканизирующий агент | Hydroxyalkyl Amide | Триглицидил изоцианурат |
| Токсичность | Non-toxic, REACH-compliant | Hazardous (regulated) |
| Температура отверждения | 160-200 ° С | 180-220 ° С |
| Погодостойкость | Excellent (long-term gloss) | Хорошо |
| Толщина пленки | Optimal for thin films | Thicker films possible |
Рынок и тенденции
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.
