Name: Evonik Dynasylan Si 264 Silane
Brand: Guangzhou Eric Wei Chemical Co., Ltd.

Features Of Evonik Dynasylan Si 264 Silane

Reactive bifunctional silane with both methoxy and epoxy functional groups for covalent bonding to inorganic and organic substrates.
Enhances adhesion between silica fillers and polymer matrices in rubber and thermoset composites.
Improves mechanical properties such as tensile strength, tear resistance, and dynamic performance in filled elastomers.
Enables reduced filler–filler interaction and lower compound viscosity during processing.
Offers hydrolytic stability under controlled storage conditions due to its alkoxysilane structure.

Typical Applications Of Evonik Dynasylan Si 264 Silane

Silica-reinforced passenger car and truck tire tread compounds.
High-performance rubber hoses, belts, and vibration dampers.
Epoxy and phenolic resin composites with mineral fillers or glass fibers.
Adhesion promoters in sealants and structural adhesives for metal–polymer bonding.
Surface treatment of pigments and fillers for improved dispersion in coatings and plastics.
