Glass and fiber materials are everywhere - but their performance depends on what’s beneath the surface. Whether in architectural glazing, automotive composites, or high-speed fiber production, Evonik empowers manufacturers with advanced surface modification and fiber sizing technologies that elevate durability, compatibility, and sustainability.
With trusted brands like DYNASYLAN® and VPS, Evonik develops and sells high-performance solutions that make glass and fiber materials smarter, stronger, and more sustainable.
Solutions by Application
Glass Surface Modification
Glass is more than transparency - it’s a high-performance material that demands protection and functionality. Evonik’s silane technologies enable durable bonding between inorganic glass surfaces and organic coatings or adhesives.
- DYNASYLAN® – Silanes that chemically bond to glass surfaces, improving scratch resistance, enabling mirror coatings, and enhancing durability in packaging and construction applications.
- VPS – Specialty siloxanes and surfactants that optimize wetting, spreading, and protection in glass coating formulations.
Benefits:
- Increased surface durability and scratch resistance
- Improved adhesion for multilayer safety glass
- Enhanced sustainability through longer product lifecycles
Fiber Sizing & Protection
Glass fibers are the backbone of modern composites—but they’re fragile during production and must bond effectively with resins. Evonik’s silane-based sizing agents and specialty additives ensure fiber integrity and compatibility from the furnace to the final composite.
- DYNASYLAN® – Used at multiple stages of fiber production to prevent breakage and enable strong bonding with polymer matrices.
- VPS – Customized additives for wetting, antifoaming, and filament protection in fiber sizing formulations.
Benefits:
- Reduced fiber breakage at high production speeds
- Enhanced resin compatibility for composite performance
- Tailored solutions for diverse fiber sizing challenges
