Evonik Dynasylan 4148 Nonionic Polyether Silane

Evonik Dynasylan 4148 is a non-ionic polyether silane designed to enhance the wetting, dispersion, and rheological properties of fillers and pigments in various polymer and solvent systems. It acts as a highly effective compatibility agent without covalent bonding activity.

Features Of Evonik Dynasylan 4148 Nonionic Polyether Silane

  1. Superior Dispersion – Ensures excellent filler and pigment wetting in resins and solvents.

  2. Viscosity Reduction – Lowers viscosity in highly filled polymer systems (e.g., aluminum hydroxide-filled polyesters).

  3. Water Compatibility – Functions as a dispersant in aqueous systems without chemical reactivity.

  4. Non-Coupling Action – Provides polar compatibility without forming covalent bonds, ideal for rheology control.

Typical Applications Of Evonik Dynasylan 4148 Nonionic Polyether Silane

  1. Composite Materials – Reduces viscosity in SMC/BMC and aluminum hydroxide-filled unsaturated polyesters.

  2. Coatings & Inks – Enhances pigment dispersion and gloss in water-based formulations.

  3. Coolant Systems – Prevents settling of anticorrosion components in glycol-based coolants.

  4. Glass Fiber Processing – Acts as a lubricant and wetting agent alongside coupling agents.

  5. High-Loading Systems – Enables higher filler/pigment loading while maintaining workable viscosity.
