High-purity hydrogen-terminated polydimethylsiloxane (H-PDMS) with controlled reactive Si–H functionality.
Low-viscosity fluid (20 cSt at 25°C) enabling excellent flow, wetting, and processability in formulation systems.
Thermally stable and chemically inert under standard processing conditions, supporting consistent performance in catalytic and crosslinking applications.
Low volatility and minimal residue, suitable for high-vacuum and precision coating environments.
Compatible with platinum-catalyzed hydrosilylation reactions, offering reliable reactivity for silicone elastomer and resin synthesis.
Base fluid for addition-cure liquid silicone rubber (LSR) formulations.
Crosslinker or functional modifier in silicone gels and soft encapsulants.
Surface treatment agent for enhancing adhesion of silicone coatings to substrates such as glass, metal, and plastics.
Reactive diluent in high-performance silicone resins and release coatings.
Key component in optical-grade encapsulants and LED packaging materials requiring clarity and thermal stability.
