Dialkoxy-terminated silicone fluid is a functional polysiloxane featuring alkoxy groups at both molecular chain ends. It combines the excellent properties of silicone, including flexibility, weather resistance, hydrophobicity and low surface tension, with the reactivity of alkoxy functional groups. Upon exposure to moisture, the alkoxy groups can hydrolyze and condense to form durable siloxane networks.

Due to its unique reactive structure, dialkoxy-terminated silicone fluid is widely used in sealants, adhesives, coatings, surface treatment agents and silicone-modified materials. It serves not only as a performance-enhancing silicone component but also as a reactive intermediate that contributes to crosslinking, improving adhesion, durability, flexibility and weather resistance of the final formulation.
