VESTANAT® EP-MF 204

VESTANAT EP-MF 204 is a solvent-free and ready-catalyzed polymethoxysilane developed by Evonik. Here are the key details about this product:

1. Chemical Composition: It is a polyfunctional methoxy silane with a non-volatile constituent of 100% by weight and an NCO-content of ≤ 0.1% by weight.
2. Physical Properties:
   • Viscosity: Approximately 1000 - 2000 mPas at 23°C.
   • Color: ≤ 100 mg Pt/l (Hazen scale), indicating its color.
3. Applications: VESTANAT EP-MF 204 can be used as a sole binder or in combination with appropriate resins, such as acrylate resins, to formulate highly scratch-resistant coatings for various substrates like wood, plastic, maintenance coatings, and potentially car refinish applications.
4. Isocyanate-Free: Similar to other products in the VESTANAT EP-MF series, VESTANAT EP-MF 204 does not require isocyanate-based hardeners for curing. It cures from 0°C, and accelerated drying above 40°C can interfere with its reactivity.
5. Storage: It can be stored in unopened containers for at least one year at ambient temperature without loss of quality. Due to its sensitivity to moisture and elevated temperatures, it should be stored in tightly sealed containers at room temperature to prevent increased entry of water and yellowing.
6. Safety: During curing, methanol is formed, so appropriate provisions to protect workers must be in place. Safety data sheets are available for detailed safety information.

VESTANAT EP-MF 204 offers a convenient solution for formulating scratch- and chemical-resistant coatings without the need for isocyanate-based hardeners, making it suitable for various coating applications across different industries. However, it's important to note that this product is still at the experimental stage of development, so definitive statements regarding its performance characteristics or production parameters cannot be made, and its commercialization and continued supply are not assured.
