Light Stabilizer 611 is a highly effective light stabilizer belonging to the HALS (Hindered Amine Light Stabilizers) class of compounds. It is primarily used to protect polymer materials (such as plastics, coatings, and rubber) from damage caused by ultraviolet (UV) radiation and thermal oxidation. Below are its detailed functions and applications:
主要功能
- UV Degradation Resistance:
- Light Stabilizer 611 effectively absorbs and disperses UV energy, preventing photodegradation and photo-oxidation of polymer materials caused by UV radiation.
- 延长材料的使用寿命，防止褪色、脆化和机械性能损失。
- Free Radical Scavenging:
- As a HALS light stabilizer, it captures free radicals generated by UV radiation and thermal oxidation, interrupting the photo-oxidation and thermal oxidation chain reactions, thereby protecting materials from further damage.
- Thermal Stability:
- Maintains stable performance even under high-temperature conditions, making it suitable for applications requiring heat resistance.
- Low Volatility:
- Exhibits low volatility, making it suitable for high-temperature processing and long-term use.
- 协同效应:
- Can be used in combination with UV absorbers and antioxidants to provide comprehensive light and thermal stabilization.
优势
- 高效率: Provides long-term UV and thermal oxidation protection.
- 兼容性: Compatible with various polymers and additives.
- Eco-Friendliness: Low toxicity, meets environmental requirements.
- Heat Resistance: Stable performance under high temperatures.
- Low Volatility: Suitable for high-temperature processing and long-term use.
使用建议
- 用量:
- 典型用量为 0.1% 至 0.5% 聚合物重量的百分比，具体取决于应用和材料类型。
- 加工温度:
- 适用于常规加工温度，但不应超过其热分解温度（通常高于 250°C）。
- 与其他添加剂的组合:
- Can be used with antioxidants, UV absorbers, and other additives for comprehensive protection.
预防措施
- 存放在阴凉、干燥的地方，避免高温和潮湿。
- 使用防护设备，避免直接接触皮肤和眼睛。
Light Stabilizer 611 is a versatile light stabilizer that significantly enhances the weatherability and service life of materials, making it widely used in industries requiring UV and thermal oxidation protection.
