Description

Siloxanes And Silicones, 3-(2-Aminoethyl)Aminopropyl Me, Di-Me, Hydroxy-Terminated is a specialized amino-functional silicone fluid with a reactive hydroxy-terminated backbone. This unique bifunctional structure provides excellent surface activity and compatibility, making it a versatile intermediate for demanding industrial applications. It is particularly valued in the formulation of advanced coatings, adhesives, and release agents where enhanced adhesion, wetting, and durability are required.

Application

• As a key coupling agent and adhesion promoter in epoxy, polyurethane, and acrylic coating systems.
• Formulation of high-performance pressure-sensitive adhesives (PSAs) and sealants for improved substrate bonding.
• Manufacture of silicone-modified polymers and resins to enhance flexibility and surface properties.
• Production of release coatings for labels and industrial tapes, offering controlled release characteristics.
• Used as a surfactant and flow control additive in specialty ink and paint formulations.
• Intermediate in the synthesis of custom silicone polyethers and other organomodified siloxanes.
• Fiber treatment and textile finishing agent to impart softness, hydrophobicity, and durability.
