LK-SIL 100ST (100–12,500 cSt)
High-Performance Industrial Grade Silicone Fluids
Product Overview
LK-SIL 100ST series represents our high-quality range of industrial-grade Polydimethylsiloxane (PDMS) fluids, available in viscosities ranging from 100 cSt to 12,500 cSt. These clear, odourless, non-reactive fluids are formulated to deliver excellent thermal and chemical stability, lubricity, and dielectric properties—making them suitable for a wide range of industrial applications.
Manufactured under stringent quality controls, LK-SIL 100ST fluids are designed to meet global regulatory standards with ultra-low cyclic siloxane content (D4, D5, D6 each <1000 ppm). These fluids are also soluble in a variety of hydrocarbon, chlorinated, and aromatic solvents, providing formulation flexibility.
