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 stability, and aesthetic appearance of materials exposed to harsh outdoor environments. This additive is essential for formulators and manufacturers in the plastics, coatings, and synthetic fiber industries seeking to enhance the durability and lifespan of their products.

Application

• Primary stabilization of polyolefins (PP, TPO, PE) for automotive parts, stadium seating, and outdoor furniture.
• UV protection in industrial and automotive coatings, including clearcoats and pigmented systems.
• Enhancing weatherability in engineering plastics such as polyamides (PA) and thermoplastic polyurethanes (TPU).
• Stabilization of adhesives and sealants for construction and automotive applications.
• Protection of synthetic fibers and textiles used in outdoor applications like tarps and awnings.
• Use in masterbatch formulations for consistent and easy dispersion in polymer processing.

Quality Control

Every batch of Tinuvin-1130 is manufactured and tested under a strict quality management system to ensure consistent performance and purity. Our products undergo rigorous quality testing to ensure compliance with industry standards. Certificates of Analysis (COA) detailing key parameters such as assay, melting point, and appearance are available upon request to support your quality assurance protocols.

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). Due to its hygroscopic (moisture-sensitive) nature, the container must be kept tightly sealed after opening to prevent moisture absorption, which can affect product performance.
