Description

Siloxanes And Silicones, Ethoxy Hydroxy Phenyl is a specialized organosilicon compound featuring a phenyl ring modified with ethoxy and hydroxy groups, attached to a siloxane backbone. This unique structure provides a blend of silicone-like properties, such as thermal stability and water repellency, with the reactivity and polarity of phenolic and ethoxy functionalities. It is a critical intermediate and performance additive for industries requiring advanced material properties, including high-performance coatings, adhesives, and release agents. The compound is identified by CAS No. 70955-49-6.

Application

• As a reactive intermediate in the synthesis of advanced silicone resins and polymers for high-temperature coatings.
• As a surface-modifying agent and coupling agent in composite materials to improve adhesion between organic polymers and inorganic fillers.
• As a key ingredient in the formulation of specialty release agents and anti-stick coatings for industrial and food-contact applications.
• As a performance additive in personal care products, such as hair conditioners and skin creams, to provide conditioning and film-forming properties.
• As a component in the production of pressure-sensitive adhesives (PSAs) and sealants to enhance flexibility and environmental resistance.
• As a building block for creating functionalized silicones used in textile finishing for water and stain repellency.
