Aminopropyl Terminated Polydimethylsiloxane
Aminopropyl-terminated polydimethylsiloxane (CAS 106214-84-0) is a reactive silicone oligomer with primary amine groups at both chain ends. The structure is commonly represented as H₂N(CH₂)₃Si(CH₃)₂O[Si(CH₃)₂O]ₙSi(CH₃)₂(CH₂)₃NH₂, with the siloxane chain length n varying by grade. The amine functionality enables covalent incorporation into epoxy, polyurethane and polyamide networks.
• Epoxy and polyurethane modification: reacts with epoxy resins and isocyanates to introduce flexible, hydrophobic siloxane segments.
• Release and anti-stick coatings: reactive additive to lower surface energy and improve mold-release performance.
• Textile and fiber treatment: imparts softness and smooth hand to synthetic and natural fibers.
• Reactive silicone intermediate: for networks requiring amine-functional siloxane segments.
