New, aqueous silane emulsion for improving the adhesion of waterborne paint systems, especially on glass and other critical substrates. Aquasil 20 is a VOC-free, storage-stable emulsion of an organofunctional silane in water.

🌊 Aquasil 20 – Aqueous, Hydrolysis-Stable Silane Emulsion

Unlike traditional silanes that are hydrolysis-sensitive, Aquasil 20 is a ready-to-use, stable silane emulsion that enhances adhesion of water-based coatings to challenging substrates like glass, aluminum, and steel.

🔍 Key Features

  • 💧 Water-based and stable
    Can be added in the let-down phase of paint formulations—unlike conventional silanes that degrade easily in water.

  • 💪 Excellent adhesion promoter
    Provides strong adhesion on glass, aluminum, and metal—without additional primers or complex steps.

  • 🧪 Single-component (1K) system
    Replaces 2K systems by enabling direct incorporation into the formulation, simplifying manufacturing.

  • 🧷 Long shelf life
    Excellent storage stability, even after 1 week of being pre-mixed.

  • 🔥 Strong hot water resistance
    Withstands 320+ minutes of hot water steaming without delamination (compared to 120 minutes with competitors)*.
