Обработка
Dynasylan® A is a ready source of silicic acid for many applications. Silicic acid in usually obtained by hydrolysis, or thermally by condensation at elevated temperature. The resulting silicic acid bonds well to many inorganic substrates and can be deposited in situ in a controlled manner. The surfaces of glass, metals, pigments, fillers and synthetic fibres can be coated with a very thin SiO2 layer in order to improve chemical and thermal stability and mechanical properties.
