Aluminum benzoate

Aluminum benzoate (CAS 555-32-8), also known as aluminium tribenzoate, is an organometallic compound used industrially as a rheology modifier and cross-linking agent.

It functions by coordinating with polymer chains and binder systems to control flow behavior and build structural integrity in coatings and specialty formulations.

In printing inks and packaging coatings, it acts as a gelling agent to adjust viscosity and prevent pigment settling during production and storage. This ensures consistent application.

Plastics and polymer compounders use it as a cross-linking promoter to improve dimensional stability and mechanical performance in finished parts. It is essential for high-performance materials.

In textile and leather finishing, it contributes to binder cross-linking, helping fix coatings and treatments that must withstand mechanical stress and washing over time.

Paper treatment processes also employ it where controlled rheology in coating slurries is critical to uniform surface coverage. This allows for high-quality finishes in paper production.

Aluminum benzoate is typically supplied as a white to off-white powder. It is available primarily in technical grade, suited for industrial coating, ink, and polymer processing applications.

Packaging options generally range from small laboratory quantities to bulk industrial quantities depending on supplier. This flexibility supports both research and large-scale manufacturing.
