Highly reactive Si–H end groups enable efficient hydrosilylation with alkenes, alkynes, and functional silanes.
Controlled molecular weight distribution ensures consistent reactivity and predictable crosslinking behavior.
Low volatility and excellent thermal stability support high-temperature processing without premature degradation.
Hydrogen termination provides superior compatibility with platinum-catalyzed silicone systems and specialty polymers.
Non-ionic, solvent-free liquid form facilitates easy handling, metering, and integration into formulation processes.
Base polymer in addition-cure liquid silicone rubber (LSR) for medical devices and precision elastomers.
Crosslinker and functional modifier in silicone pressure-sensitive adhesives (PSAs) for high-performance tapes.
Reactive diluent and chain extender in silicone resins for heat-resistant coatings and encapsulants.
Building block for synthesizing silicone surfactants, coupling agents, and hybrid organic-inorganic materials.
Key ingredient in platinum-catalyzed release coatings for paper, film, and composite manufacturing.
