Applications of bis(3-aminopropyl)-terminated polydimethylsiloxane in multiple industries

Bis(3-aminopropyl)-terminated polydimethylsiloxane is an amino‑terminated silicone oil that, on the one hand, inherits the low surface energy, excellent thermal stability, and outstanding flexibility characteristic of polydimethylsiloxane backbones; on the other hand, the aminopropyl functional groups at both ends of the molecule confer high reactivity and versatile functionalization potential, making it an indispensable material across a wide range of applications.

(1) Polymer Material Modification: The “Performance Amplifier” for Engineering Materials

Amines can react with epoxy groups, isocyanate groups, aldehydes, ketones, and other functional groups, providing a key pathway for the “customized modification” of materials such as polyimides, polyamides, polyurethanes, and epoxy resins. This enables the modified materials to simultaneously exhibit the low surface energy, excellent thermal stability, and superior aging resistance characteristic of organosilicon compounds, while retaining the strength and rigidity inherent to the base substrate.

(2) Personal Care Sector: The “Invisible Caregiver” for Hair

Amino-terminated silicone oil is an important additive in personal care products such as shampoos, conditioners, and hair‑conditioning treatments. Due to its strong adsorption properties and its relatively long siloxane molecular chains, it can interact with hydroxyl, carboxyl, and other functional groups on the hair surface. ^[1] It forms a smooth, protective film on the hair’s surface, tames frizz and split ends, and leaves hair feeling moisturized, silky, and flowing. It also improves combability when wet or dry and provides deep repair for damaged hair.

(3) Textile Industry: The “Softness Magician” of Fabric Softening Finishing

The demand for textile fabrics that are “soft, skin-friendly, and wash‑resistant” can be precisely met by amino‑terminated silicone oil. The high reactivity of the amino groups enables efficient bonding with fiber surfaces, allowing siloxane chains to adsorb in an oriented manner and reduce the coefficient of friction between fibers. This imparts a soft, smooth, and full hand feel while delivering excellent wash durability and breathability.
