Light Stabilizer 610: Detailed Functions and Applications

Light Stabilizer 610 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:

Key Functions

1. UV Degradation Resistance:
   • Light Stabilizer 610 effectively absorbs and disperses UV energy, preventing photodegradation and photo-oxidation of polymer materials caused by UV radiation.
   • Extends the service life of materials, preventing discoloration, embrittlement, and loss of mechanical properties.
2. 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.
3. Thermal Stability:
   • Maintains stable performance even under high-temperature conditions, making it suitable for applications requiring heat resistance.
4. Low Volatility:
   • Exhibits low volatility, making it suitable for high-temperature processing and long-term use.
5. Synergistic Effects:
   • Can be used in combination with UV absorbers and antioxidants to provide comprehensive light and thermal stabilization.

优势

• High Efficiency: 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.

Usage Recommendations

1. Dosage:
   • Typical dosage is 0.1% to 0.5% of the polymer weight, depending on the application and material type.
2. Processing Temperature:
   • Suitable for conventional processing temperatures but should not exceed its thermal decomposition temperature (usually above 250°C).
3. Combination with Other Additives:
   • Can be used with antioxidants, UV absorbers, and other additives for comprehensive protection.

预防措施

• Store in a cool, dry place away from high temperatures and moisture.
• Use protective equipment to avoid direct contact with skin and eyes.

Light Stabilizer 610 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.
