Description

Silanetriol, [3-(Dimethylamino)Propyl]- (9Ci) is a specialized organosilicon compound featuring a reactive silanetriol head group and a tertiary amine-functionalized propyl linker. This unique bifunctional structure makes it a highly effective coupling agent and surface modifier, bridging organic polymers with inorganic substrates. It is essential for formulators and material scientists in the coatings, adhesives, and composites industries seeking to enhance interfacial adhesion and material performance. The compound is supplied under strict quality control to ensure batch-to-batch consistency for demanding industrial applications.

Application

• Adhesion Promoter in epoxy, polyurethane, and acrylic-based coatings and adhesives for metals, glass, and plastics.
• Surface Modification Agent for silica, glass fibers, and other mineral fillers to improve dispersion and compatibility in polymer composites.
• Crosslinking Agent and co-monomer in the synthesis of specialty silicone resins and hybrid organic-inorganic polymers.
• Primer Component for pre-treatment surfaces to significantly improve the durability and water resistance of subsequent layers.
• Catalyst and Intermediate in organic synthesis and pharmaceutical manufacturing due to its reactive silanol and amine groups.
• Textile and Paper Treatment to impart water repellency, softness, or specific functional properties to fibers.
