Solutions by Application
Surface Protection & Corrosion Resistance
Ideal for concrete, stone, and metal surfaces exposed to moisture, pollution, and wear.
- Protectosil® – Silane-based treatments that penetrate deeply into mineral building materials to protect against water ingress, corrosion, and weathering. Protectosil® CIT, WA CIT, WS CIT 200 and DRY CIT are corrosion inhibitors for steel-reinforced concrete.
- VESTANAT® H12MDI – Cycloaliphatic diisocyanate used to produce polyurethanes exhibiting excellent light stability, weatherability and mechanical properties.
Roofing Membranes & Sealants
Used in waterproofing systems, flexible membranes, and construction sealants.
- VESTINOL® – Very effective, high-molecular-weight plasticizer with a very balanced property profile.
- ELATUR® – Plasticizers for demanding applications. ELATUR® TM offers very low volatility and an excellent migration profile; ELATUR® DINCD combines low-temperature flexibility with very low volatility.
Films, Fibers & Sheets
Applied in packaging, textiles, and industrial films requiring strength and adaptability.
- Butene-1 & Isobutene – Key monomers for producing polyolefins with tailored mechanical properties.
The Evonik Advantage
- Reliable Chemistry: Engineered for performance, trusted by global manufacturers.
- Waterborne Options: Protectosil® WS 610 is an organofunctional siloxane-based waterborne emulsion with almost no volatile organic components; further waterborne emulsions are available across the Protectosil® WS range.
- Expert Collaboration: Our teams work with you to optimize formulations and unlock new possibilities.
