Hydrogen Silicone Fluids: Guide

Hydrogen silicone fluids are a type of silicone oil containing reactive Si-H bonds, making them highly versatile in various applications. These fluids are commonly used as crosslinkers in the production of addition-cure liquid silicone rubber (LSR), enhancing properties like elongation and tear strength. They also serve as waterproofing agents for materials such as fabrics, glass, ceramics, leather, and concrete, forming durable hydrophobic coatings. Additionally, hydrogen silicone fluids find applications in textile softeners, release agents, and as intermediates in organo-modified silicone synthesis. Their reactivity can be tailored by adjusting the Si-H content, offering flexibility in formulation.
