The formulation of high-performance adhesives and sealants relies heavily on specialized chemical additives that can bridge dissimilar materials and enhance long-term durability. Bis(3-triethoxysilylpropyl)amine (CAS 13497-18-2) has emerged as a critical component in this sector, offering significant improvements in adhesion, moisture resistance, and crosslinking capabilities. As a leading manufacturer and supplier, we are dedicated to providing formulators with this essential silane coupling agent.

At its core, Bis(3-triethoxysilylpropyl)amine is a bifunctional molecule designed to optimize interfacial interactions. The triethoxysilyl end of the molecule readily hydrolyzes in the presence of moisture to form reactive silanol groups. These silanols can then chemically bond with hydroxyl groups present on inorganic surfaces such as glass, metals, and ceramics, creating a strong, covalent link. This effectively primes the surface for better adhesion.

The amine functional group on the other end of the molecule is highly reactive with various organic polymer systems commonly found in adhesives and sealants, including epoxies, polyurethanes, and silicones. It acts as an adhesion promoter by forming chemical bonds or strong physical interactions with the polymer matrix. This dual action – bonding to the substrate and integrating with the adhesive/sealant matrix – is what makes it such a powerful coupling agent.

Furthermore, the amine group can also serve as a catalytic site or actively participate in crosslinking reactions, particularly in moisture-curing systems. This leads to enhanced cohesive strength and improved resistance to water and environmental degradation, extending the service life of the bonded assembly. Procurement managers looking to buy this essential intermediate can rely on our consistent supply and quality assurance. We are committed to being a dependable supplier for manufacturers across various industries, ensuring you have access to the critical building blocks for your advanced adhesive and sealant formulations.
