Amino Silane Oligomer

1. Characteristics

Silane oligomers are synthesized from specific silane coupling agents as the base material, combined with selected end-capping agents, catalysts, and stabilizers, resulting in a polymerization degree of 3–5. Compared to conventional silane coupling agents, they feature longer molecular chains, enhanced chain flexibility, improved system stability, and offer superior adhesion, boiling water resistance, chemical resistance, abrasion resistance, heat resistance, weatherability, and unique flexibility.

Amino silane oligomers are low-molecular-weight polymers formed by controlled hydrolysis and condensation of amino silane monomers. They combine the reactivity of organic amine groups with the excellent properties of the siloxane backbone. Compared to traditional silane monomers, they provide more uniform film formation, higher storage stability, and improved functionality, acting as a “molecular bridge” between organic systems and inorganic substrates. They hold irreplaceable value in various industrial fields such as metal surface treatment, baking paints, and waterborne coatings.

2. Features

It contains no volatile organic components. Compared with monomeric silanes, it provides more uniform film formation, longer storage life, and higher stability. The typical addition level is 0.5–5%, and it can be directly diluted with water for use. Substitute of Evonik Dynasylan? HYDROSIL 1151 and Momentive Silquest Y-15744
