  • Corrosion protection

  • Adhesion promotion

  • Suitable selection for every application 

Metal pretreatment is essential in industries such as automotive, engineering and construction to produce corrosion-resistant, durable products. Silane-based formulations, such as Evonik’s DYNASYLAN® brand, offer an effective and environmentally friendly solution. Silanes perform two main functions: corrosion protection and adhesion promotion. Mixed with corrosion inhibitors, silanes form a protective layer against corrosion. They are a sustainable alternative to heavy metal additives, reducing disposal costs and environmental impact. The unique chemical structure of silanes makes them ideal adhesion promoters. Organofunctional silanes bond to metal surfaces, providing strong adhesion for paints and coatings, preventing premature flaking, and extending coating service life.

The treatment’s effectiveness depends on choosing the right silane. DYNASYLAN® products offer tailor-made solutions for various metal surfaces and applications, from simple rust prevention to the highest protection class C5. By using silanes, manufacturers can improve product quality and durability while making production more environmentally friendly, chromium-free, and cost-effective.
