3,5-Di-tert-butyl-4-hydroxybenzoic acid

UV-612

• Stability: Stable at room temperature under normal conditions
• Chemical characteristics: Exhibits weak acidity and phenolic antioxidant properties
• Combustibility: Combustible; may decompose at high temperatures to produce carbon monoxide and other carbon oxides
• Incompatible materials: Strong oxidizing agents and strong alkalis
• Application: Used as an intermediate for synthesizing UV absorbers and antioxidants

• Polymer Additive Intermediate: Used to synthesize UV-2908 and other UV absorbers and phenolic antioxidants
• Plastics & Rubber: Helps improve anti-aging resistance, weather resistance, and yellowing resistance in polyolefins, PVC, ABS, and epoxy resins
• Coatings & Inks: Acts as a light stabilizer and antioxidant component in outdoor coatings, wood finishes, and printing inks
• Pharmaceuticals & Fragrances: Used as an intermediate in antioxidant and preservative-related formulations
• Industrial Cleaners: Incorporated into metal surface treatment formulations for oxidation resistance and corrosion inhibition

• Skin Contact: Remove contaminated clothing immediately. Wash skin thoroughly with plenty of water and soap for at least 15 minutes. Seek medical attention if irritation persists.
• Eye Contact: Rinse immediately with plenty of water for at least 15 minutes while holding the eyelids open. Seek medical attention promptly.
• Inhalation: Move the affected person to fresh air and keep the airway clear. Administer oxygen if breathing is difficult. If breathing stops, provide artificial respiration and seek medical help immediately.
• Ingestion: Rinse mouth with water. Do not induce vomiting. Seek medical attention immediately.
• Fire: Use dry chemical powder or carbon dioxide for extinguishing. Do not use a direct water jet, as it may cause splashing.

• Packaging: Sealed packaging with an inner plastic bag (20 kg per package).
• Storage Conditions: Store at room temperature in a cool, dry, and well-ventilated warehouse. Keep away from heat sources and open flames.
• Storage Requirements
  1. Store separately from strong oxidizing agents, strong alkalis, and food products.
  2. Keep containers tightly closed to protect the product from moisture and light.
  3. Stack packages at least 10 cm above the ground and keep them away from heating systems and pipelines.

• Ventilation & Dust Control: Handle in a fume hood or with adequate exhaust ventilation to prevent dust generation and inhalation.
• Fire Prevention: Keep open flames, sparks, and smoking away from the production area. Use explosion-proof electrical equipment where required.
• Incompatible Materials: Do not store or mix with strong oxidizing agents or strong alkalis.
• Spill & Waste Disposal: Collect small spills with dry sand or inert absorbent materials. Dispose of waste through a licensed hazardous waste contractor. Do not discharge directly into the environment.
