Polymethylhydrosiloxane

Polymethylhydrosiloxane (CAS 63148-57-2 ), commonly abbreviated as PMHS, is a hydrogen-functional silicone polymer used across industrial and specialty chemical markets. Its reactive Si-H groups make it a practical crosslinker, reducing agent, and surface treatment agent in formulations where durable hydrophobic performance is required. In textile and leather finishing, PMHS delivers soft-hand effects and water-repellent coatings that withstand repeated washing cycles for high-performance materials. Building and construction formulators use it to impregnate masonry, concrete, and stone surfaces, creating long-lasting moisture barriers without altering substrate appearance. Personal care manufacturers incorporate PMHS as a conditioning and slip agent in hair and skin formulations where a lightweight, non-greasy feel is the target. In lubricant and metalworking applications, it functions as an anti-foam additive and process aid, controlling foam in cutting fluids and industrial oil systems. PMHS is supplied as a clear to slightly hazy liquid, with viscosity grades ranging from low to medium to suit different coating and formulation processes. It is available in technical grade , which covers the majority of industrial applications across construction, textiles, and lubricants for global buyers.
