Physicochemical Properties

Typical Applications

Typically used in:

• Plastics and Polymers: Integrated into synthetic resins, plastics, toys, and molded parts to inhibit UV degradation, preventing yellowing and mechanical deterioration from sunlight exposure.
• Industrial Coatings and Finishes: Formulated into clear coats, lacquers, and furniture finishes to preserve surface integrity and color stability underneath light exposure.
• Inks and Adhesives: Functions as a photo-initiator or stabilizer component in specialized UV-curable inks and packaging adhesives to accelerate drying and maintain bond performance.
• Synthetic Fibers: Added during the masterbatch process of textiles and synthetic materials to provide structural UV protection.

Packaging

Supplied in standard commercial 25kg fiber drums lined with double PE bags, or specialized bulk packaging setups designed to protect the crystalline powder from compaction and atmospheric moisture.

Storage

Store in a cool, dark, and dry warehouse with temperatures preferably kept below 30°C. Keep containers tightly sealed to prevent contamination. Keep separated from strong oxidizing agents and direct heat or light sources to avoid degradation.

FAQ

Are batch-specific documents provided upon commercial procurement?

Yes, a comprehensive Certificate of Analysis (COA) detailing purity, melting range, and ash content is generated for every shipment batch, along with standard TDS and SDS.

What is the primary function of Benzophenone-3 in plastic manufacturing?

It acts as a competitive UV absorber, absorbing harmful ultraviolet radiation and dissipating it as harmless thermal energy, thereby preventing polymer chain scission, discoloration, and embrittlement.

Is this grade suitable for direct food contact applications?

Specific migration limits and local regulations apply to substances leaching from food packaging. Please consult our technical department with your exact regulatory framework to verify compliance.

What is the solubility profile of Benzophenone-3 for solvent-based formulations?

It is highly lipophilic (oil-soluble) and dissolves easily in standard organic solvents like alcohols, esters, ketones, and aromatic hydrocarbons, making it highly compatible with solvent-borne resins.
