High active hydrogen content (≥4.5 wt%) enabling efficient hydrosilylation reactions.
Low viscosity (30–50 cSt at 25°C) for excellent processability and uniform dispersion.
Excellent thermal stability up to 200°C, supporting high-temperature curing processes.
High purity with minimal cyclic siloxane residues (<0.5%), ensuring consistent crosslinking performance.
Compatible with platinum-based catalysts and common functional silicones (e.g., vinyl-terminated PDMS).
Hydrosilylation-curable liquid silicone rubber (LSR) formulations.
Crosslinking agent in heat-cured silicone gels for electronics encapsulation.
Functional additive in pressure-sensitive adhesive (PSA) modifiers for enhanced cohesion.
Surface treatment agent for silica fillers in high-performance silicone elastomers.
Key component in optical-grade silicone resins for LED lens encapsulation.
