Features Of Fadian Chemical FD-450 Silane Coupling Agent

  1. Highly reactive amino-functional silane with dual functionality for covalent bonding to both inorganic substrates and organic polymers.

  2. Excellent hydrolytic stability in neutral to mildly acidic aqueous systems, enabling reliable storage and processing.

  3. Low volatility and favorable handling safety profile compared to chlorosilane-based alternatives.

  4. Enhances interfacial adhesion, mechanical strength, and moisture resistance in filled composites and coatings.

  5. Compatible with common solvents (e.g., isopropanol, ethanol, acetone) and easily dispersible in water at controlled pH.

Typical Applications Of Fadian Chemical FD-450 Silane Coupling Agent

  1. Surface modification of silica, glass fibers, and mineral fillers in rubber and thermoplastic composites.

  2. Adhesion promoter in automotive and industrial primers for metal-to-paint or plastic-to-coating systems.

  3. Performance enhancer in high-strength epoxy and polyurethane adhesive formulations.

  4. Moisture-cure additive in silicone sealants and RTV elastomers to improve substrate bonding.

  5. Functionalization agent for nanoscale fillers (e.g., nano-silica, clay) in advanced polymer nanocomposites.
