Features Of Evonik Dynasylan Isocyanurate 88445 1,3,5-Tris(3-trimethoxysilylpropyl)isocyanurate

  1. Highly crosslinkable tri-functional silane with isocyanurate core enabling robust 3D network formation in hybrid coatings and composites.

  2. Excellent hydrolytic stability due to sterically hindered isocyanurate ring and optimized alkoxy group reactivity.

  3. Enhanced adhesion promotion between organic polymers (e.g., epoxies, polyurethanes) and inorganic substrates (glass, metals, minerals).

  4. Low volatility and favorable handling characteristics compared to mono- or di-functional alkoxysilanes.

  5. Enables covalent integration into sol-gel systems without significant premature condensation under ambient processing conditions.

Typical Applications Of Evonik Dynasylan Isocyanurate 88445 1,3,5-Tris(3-trimethoxysilylpropyl)isocyanurate

  1. Adhesion promoters in high-performance automotive clearcoats and primerless coating systems.

  2. Hybrid matrix modifiers for fiber-reinforced polymer composites (e.g., carbon/glass fiber epoxy prepregs).

  3. Crosslinking agents in moisture-curable silicone-modified polyurethane sealants and adhesives.

  4. Surface functionalization additives for silica-based nanofillers in engineering thermoplastics.

  5. Stabilizing agents in colloidal silica dispersions for advanced ceramic casting and refractory binders.
