Description

Monohexacosyl Terminated Polydimethylsiloxane, 45 Cst is a specialized organosilicon fluid featuring a long-chain hexacosyl group at each polymer terminus, which imparts unique surface-active and compatibility properties. This specific 45 centistoke viscosity grade offers an optimal balance between flow characteristics and film-forming ability, making it a valuable performance additive. It is primarily utilized in the formulation of advanced lubricants, release agents, and surface treatments where enhanced slip, hydrophobicity, and thermal stability are required.

Application

• As a high-performance internal/external lubricant and slip agent in plastics and polymer processing.
• As a key component in high-temperature, non-carbonizing mold release agents for rubber and plastics manufacturing.
• In the formulation of specialized polishes, coatings, and surface treatments to impart water repellency and a smooth feel.
• As a compatibilizer and processing aid in silicone-modified organic polymer blends.
• In fiber and textile treatments to reduce friction and improve fiber handling.
• As a base fluid or additive in specialty lubricants for demanding industrial applications.
• For surface modification of pigments and fillers to improve dispersion in organic matrices.
