Molecular Structural Formula:

Note: Items marked with * are control indicators when customers have special requirements.

Properties: This product is a white to pale yellow waxy solid or liquid, with a melting point above 28°C, boiling point of 400°C, specific gravity of 0.895. It is insoluble in water but easily soluble in organic solvents such as toluene. The typical addition amount is 0.1-3.0%.
Applications: This product is a hindered amine light stabilizer, primarily used as an ultraviolet light stabilizer for thermoplastic polymer materials such as polyacetal, acrylonitrile-butadiene-styrene copolymer (ABS), and styrene-acrylonitrile copolymer (SAN); engineering plastics such as polyethylene (PE), polypropylene (PP), polyamide (PA), acrylonitrile-styrene-acrylate copolymer (ASA), and high-impact polystyrene (HIPS); thermoplastic polyolefin elastomers (TPO), and polyurethane (PU). It is widely used in fibers, films, sheets, pipes, belts, moldings, and other products made from the above materials. Additionally, this product serves as an antioxidant additive for ashless lubricants.

This product features the following characteristics: 1. It exhibits good synergistic effects with other hindered amine light stabilizers, especially high molecular weight hindered amine light stabilizers (such as 944, 119) and benzoate UV absorbers (such as UV328). 2. In polyolefin-based products, it provides excellent color stability, gloss retention, and durability. 3. Compared to other low molecular weight hindered amine light stabilizers, it has good compatibility and solubility with polyolefins.

Storage: Store in a sealed container in a cool, dry place.

Packaging: 25kg, 180kg/drum or as per customer requirements.

Shelf Life: 1 year.
