Technical Textiles

Silicones are suitable for coating almost any kind of fabric. The art of formulation requires a great deal of experience and creativity, and a wealth of knowledge about relevant chemical and processing relationships. This is an area in which WACKER’s technical service excels: we will help you with the often tricky task of matching product, coating system and substrate to obtain the best results.
