Silico® HF2020 Methyl Hydrogen Silicone Fluid
Silico® HF2020(CAS 63148-57-2) is a trimethylsilyl-terminated methyl hydrogen silicone fluid designed for use in a variety of industrial applications requiring reactive hydrogen groups. It offers excellent thermal stability, water repellency, and compatibility with a wide range of organic and inorganic materials. Its unique structure enables it to act as a crosslinking agent or surface modifier in coatings, water-repellent treatments, and silicone rubber formulations.
