Features Of Evonik Dynasylan SIVO 214 Blend of primary and secondary aminofunctional silanes

  1. Optimized dual-amine functionality combining primary (–NH₂) and secondary (–NH–) amine groups for balanced reactivity and crosslink density.

  2. Enhanced hydrolytic stability compared to mono-aminosilanes, enabling longer shelf life and improved formulation robustness.

  3. Excellent compatibility with epoxy, polyurethane, and acrylic resin systems without phase separation or gelling.

  4. Promotes strong covalent bonding between organic polymers and inorganic substrates such as glass, metals, and mineral fillers.

  5. Reduces moisture sensitivity during curing, supporting reliable performance in humid processing environments.

Typical Applications Of Evonik Dynasylan SIVO 214 Blend of primary and secondary aminofunctional silanes

  1. Adhesion promoters in structural adhesives and automotive bonding systems.

  2. Surface modifiers for silica, clay, and calcium carbonate fillers in high-performance composites.

  3. Hybrid coupling agents in epoxy-based encapsulants and electrical potting compounds.

  4. Functional additives in waterborne and solventborne industrial coatings for metal and concrete substrates.

  5. Reactive dispersants in pigment concentrates and rheology-modified polymer dispersions.
