Features Of Evonik Dynasylan HYDROSIL 2926 Epoxy-functional oligomeric siloxane aqueous solution

  1. Water-based, VOC-compliant formulation enabling sustainable surface modification without organic solvents.

  2. Epoxy-functional siloxane oligomers provide covalent bonding to both inorganic substrates (e.g., glass, metals, minerals) and organic polymers.

  3. Enhances adhesion, corrosion resistance, and hydrophobicity while maintaining substrate breathability.

  4. Stable aqueous dispersion with pH-adjusted neutrality for compatibility with waterborne coatings and adhesives.

  5. Enables one-step priming and functionalization—reducing processing steps and energy consumption.

Typical Applications Of Evonik Dynasylan HYDROSIL 2926 Epoxy-functional oligomeric siloxane aqueous solution

  1. Primer additive for waterborne automotive OEM and refinish coatings on metal and composite substrates.

  2. Adhesion promoter in architectural silicone and hybrid sealants for concrete, masonry, and aluminum.

  3. Surface modifier for fiber-reinforced polymer (FRP) composites in wind energy and transportation sectors.

  4. Functional binder in mineral-based renders and facade systems to improve water repellency and durability.

  5. Pre-treatment for galvanized steel and aluminum prior to powder coating or cathodic electrodeposition (EDP).
