Calcium octanoate

Calcium octanoate (CAS 6107-56-8), also known as calcium octoate or calcium caprylate, is a calcium salt of caprylic acid used as a functional additive across polymer processing, coatings, and lubrication applications.

It acts primarily as a catalyst, crosslinking agent, and lubricant component in industrial formulations. In coatings and sealants, it functions as a drier co-catalyst, supporting metal drier systems to promote oxidative curing.

This additive is essential for alkyd-based paints and varnishes. Polymer processors use it as a stabilizer and processing lubricant in PVC and other thermoplastic compounds, where it reduces friction and improves melt flow.

During extrusion or calendering, it ensures consistent material behavior. In adhesive and elastomer formulations, it contributes to crosslinking and curing reactions, influencing final bond strength and elasticity.

Lubricant manufacturers incorporate it as a metal soap component in grease formulations and metalworking fluids. Calcium octanoate is supplied as a liquid or paste, with solid forms available depending on concentration.

The Technical grade is the standard offering for industrial applications in coatings, polymers, and lubricants. Specifications and active metal content vary by supplier, so buyers typically request a certificate of analysis.

This documentation confirms the specific calcium content and purity levels required for production. The material remains a versatile choice for manufacturers seeking reliable performance in demanding chemical environments.
