Bis-(1-octyloxy-2,2,6,6-tetramethyl-4-piperidinyl) Sebacate

Product Overview

Light Stabilizer 123 is a high-efficiency hindered amine light stabilizer (HALS) specifically engineered to protect polymeric materials from photodegradation. Chemically known as Bis-(1-octyloxy-2,2,6,6-tetramethyl-4-piperidinyl) sebacate, this advanced additive provides exceptional durability against UV radiation. Its unique liquid physical state facilitates easy handling and integration into various formulation systems, making it a preferred choice for manufacturers seeking consistent quality and performance.

As a premium specialty chemical, this stabilizer operates through a regenerative cycle that scavenges free radicals generated during UV exposure. This mechanism significantly extends the service life of coated surfaces, preventing common failure modes such as chalking, cracking, and gloss loss. The compound is particularly valued in demanding environments where long-term aesthetic and structural integrity are paramount.

Key Specifications

Our manufacturing process ensures strict adherence to international quality standards. Each batch is rigorously tested to guarantee purity and performance consistency. The following table outlines the critical physical and chemical parameters:

Performance Advantages

Light Stabilizer 123 offers distinct advantages over conventional solid stabilizers, primarily due to its liquid form and chemical structure. Key benefits include:

• Superior compatibility with high solids and water-borne coating systems.
• Excellent solubility in organic solvents and resin binders.
• Low volatility ensures long-term protection without evaporative loss.
• Enhanced resistance against hydrolysis in acid-catalyzed environments.
• Synergistic effects when combined with UV absorbers for maximum protection.

Industrial Applications

This stabilizer is extensively used in the protective coatings industry. It is especially effective in two-component metallic thermosetting acrylate systems and one-component opaque thermosetting formulations. Primary application sectors include automotive OEM finishes, industrial maintenance coatings, and decorative wood stains. In automotive refinish paints, it prevents gloss reduction and color change caused by prolonged sun exposure. For wood coatings, it protects against delamination and blistering when used alongside compatible UV absorbers.

The liquid nature of this product enables easy emulsification into water-borne systems, aligning with modern environmental regulations regarding VOC emissions. Manufacturers can incorporate this stabilizer into both base coats and clear coats to ensure comprehensive protection throughout the coating layers.

Storage and Handling

To maintain optimal quality, store containers in a cool, dry place away from direct sunlight. Ensure lids are tightly closed to prevent contamination or moisture absorption. Our company provides comprehensive technical support, including safety data sheets and certificates of analysis for every shipment. As a global manufacturer, we are committed to supplying high-purity functional additives that meet the rigorous demands of the modern chemical industry.
