JADEWIN 699 Amino‑Functional Silane Coupling Agent

Poor interfacial bonding between organic resins and inorganic substrates, poor filler dispersion, high system viscosity, insufficient adhesion and inferior water/corrosion resistance are common bottlenecks limiting product performance in coatings, adhesives, composites and rubber‑plastic modification. JADEWIN 699 is an amino‑functional organic silane coupling agent specially developed to solve organic‑inorganic interfacial compatibility challenges. It acts as a molecular bridge connecting inorganic substrates and organic resins to comprehensively upgrade material performance.

JADEWIN 699 is an amino‑functional organic silane coupling agent with dual reactive groups in its molecular structure. The alkoxy groups on one end react with inorganic materials such as glass, metals and mineral fillers. The reactive amino functional groups on the other end can react or achieve good compatibility with organic resins including epoxy, polyurethane and acrylics. It bonds two phases at molecular level to optimize interfacial performance.

It is a pale‑yellow transparent liquid with high solid content and stable performance during storage and application. In filled modification systems, it effectively improves the dispersion of inorganic fillers in polymer matrices and reduces system viscosity for better processing flowability. It also enhances mechanical strength and interfacial stability of composites and mitigates performance deterioration caused by phase separation.

For coatings and adhesives, JADEWIN 699 works as an efficient adhesion promoter. It greatly improves bonding strength of coatings and adhesives onto inorganic substrates like glass, metal and ceramic. Meanwhile it boosts water resistance and corrosion resistance of films, reducing defects such as blistering, peeling and delamination and extending service life of finished products.
