High-purity, low-viscosity hexamethyldisiloxane (HMDSO) fluid with controlled volatility and excellent thermal stability.
Ultra-low water content (< 10 ppm), ensuring compatibility in moisture-sensitive silicone synthesis and catalyst systems.
Non-reactive siloxane backbone provides inertness toward acids, bases, and common organic reagents under standard processing conditions.
Low surface tension and high spreading capability, facilitating uniform wetting in coating and release agent formulations.
Meets stringent VOC regulations—non-halogenated, non-toxic, and fully compliant with REACH and RoHS directives.
Silicone polymer chain termination agent in the production of polydimethylsiloxanes (PDMS) and functional silicones.
Carrier solvent and diluent for silicone-based antifoams, defoamers, and foam control agents in industrial process streams.
Key component in high-performance mold release coatings for precision rubber, polyurethane, and composite manufacturing.
Surface modifier in specialty coatings to enhance hydrophobicity, slip, and abrasion resistance on plastics and metals.
