Description

Tinuvin-1130 is a high-performance, low-basicity hindered amine light stabilizer (HALS) designed for long-term protection of polymers against photo-oxidative degradation. Its effectiveness is critical for maintaining the mechanical properties, color, and surface integrity of materials exposed to harsh environmental conditions. This additive is essential for formulators and manufacturers in the plastics, coatings, and automotive industries seeking to enhance the durability and lifespan of their products.

Application

• Primary stabilization of polyolefins (PP, TPO, PE) for automotive exterior parts, garden furniture, and agricultural films.
• Protective coatings for automotive clearcoats, industrial paints, and wood finishes to prevent gloss loss, cracking, and chalking.
• Stabilization of engineering plastics such as polyamides (PA) and thermoplastic polyurethanes (TPU) used in demanding applications.
• Additive in adhesives and sealants to improve weatherability and prevent embrittlement.
• Protection for synthetic fibers and textiles against UV-induced strength loss and color fading.
• Use in masterbatch formulations for consistent and efficient dispersion in final polymer processing.

Quality Control

Our Tinuvin-1130 is manufactured under a strict quality management system to ensure batch-to-batch consistency and high performance. Each lot is tested against rigorous internal specifications, which typically include assay, color, and melting point analysis. A Certificate of Analysis (COA) detailing the specific results is provided with every shipment to guarantee compliance with your formulation requirements.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated place at room temperature (15-25°C). This product is hygroscopic (moisture-sensitive); keep the original container tightly sealed to minimize exposure to atmospheric humidity.
