描述

Chemical Name.
2,2,6,6-tetramethyl-4-piperidine stearate
CAS No.:167078-06-0/86403-32-9(EU)
Appearance:White waxy solid
Melting point:>28°C
Characteristics and application
Characteristics] A low molecular weight hindered amine light stabilizer with excellent compatibility and solubility with polyolefin resins, which greatly reduces the precipitation and frosting phenomenon.
【Application】The product is suitable for most polymers, including injection molding, film materials and tapes and other PP products, it can also be used in polyacetal, polyamide, styrene polymers as a light stabilizer, and at the same time, it can be made into concentrated masterbatch.

应用领域

1. Plastics Industry:
   • Used in polypropylene (PP), polyethylene (PE), polyvinyl chloride (PVC), and other plastic products to prevent fading, embrittlement, and performance loss caused by UV radiation.
   • Common applications: outdoor furniture, automotive parts, plastic films, pipes, etc.
2. Coatings and Inks:
   • Protects coatings and inks from UV damage, preventing fading and chalking.
   • Common applications: automotive coatings, architectural coatings, industrial coatings, etc.
3. Rubber Products:
   • Protects rubber materials (e.g., tires, seals) from UV radiation and ozone damage.
4. Textiles:
   • Enhances the lightfastness of synthetic fibers (e.g., polyester, nylon), preventing fading and loss of strength.
5. Other Fields:
   • Can be used in adhesives, sealants, and other polymer materials for light stabilization.

优势

• High Efficiency: Provides long-term UV protection.
• 兼容性: Compatible with various polymers and additives.
• Eco-Friendliness: Low toxicity, meets environmental requirements.
• Heat Resistance: Stable performance under high temperatures.

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 3853 is a versatile light stabilizer that significantly enhances the weatherability and service life of materials, making it widely used in industries requiring UV protection.
