Features Of Evonik Dynasylan LT20 Environmentally friendly neutral crosslinker

  1. Neutral pH formulation eliminates acid-catalyzed corrosion risks to metals and sensitive substrates.

  2. Low-VOC and solvent-free composition supports compliance with stringent environmental regulations (e.g., EU REACH, VOC directives).

  3. Hydrolytically stable silane-based chemistry enables extended shelf life and consistent performance in aqueous systems.

  4. Enables room-temperature curing without external catalysts, reducing energy consumption and processing complexity.

  5. Enhances adhesion between organic polymers and inorganic surfaces (e.g., glass, metals, minerals) via covalent siloxane bonding.

Typical Applications Of Evonik Dynasylan LT20 Environmentally friendly neutral crosslinker

  1. High-performance silicone sealants and RTV adhesives for construction and automotive assembly.

  2. Waterborne acrylic and polyurethane coatings requiring improved substrate wetting and interfacial durability.

  3. Mineral-filled composites and grouts where alkali-sensitive fillers (e.g., calcium carbonate, wollastonite) are used.

  4. Hybrid sol-gel formulations for protective anti-corrosion primers on steel and aluminum substrates.

  5. Functionalized silica dispersions and nanocomposite matrices for advanced elastomers and encapsulants.
