Description

Lodyne S is a specialized fluorochemical surfactant and surface modifier, identified by CAS No. 66039-00-7. This high-performance additive is engineered to impart exceptional oil, water, and soil repellency to a wide range of substrates. It is a critical component for industries requiring advanced surface properties, such as enhanced durability, reduced surface energy, and improved chemical resistance. Key users include manufacturers in the textile, paper, and polymer processing sectors.

Application

• As a key ingredient in high-performance textile finishes for water-repellent, stain-resistant, and oil-repellent fabrics.
• As a surface treatment agent for paper and paperboard to provide grease resistance and barrier properties.
• As an additive in polymer coatings and films to lower surface energy and improve release characteristics.
• As a processing aid and anti-fog agent in the production of plastic films and packaging materials.
• For imparting soil and stain resistance to carpets, upholstery, and other treated surfaces.
• In the formulation of specialty cleaners and polishes where surface protection and repellency are desired.
