LF-H101L Low Hydrogen Silicone Fluid

Name: LF-H101L Low Hydrogen Silicone Fluid
Brand: Nanjing Silfluo New Material Co., Ltd.
Availability: InStock

Silfluo LF-H101L is a methylhydrogen-dimethylsiloxane copolymer (CAS 63148-57-2), a partially hydrogenated silicone fluid in which Si–H-bearing methylhydrogensiloxane units are interspersed with non-reactive dimethylsiloxane units along the backbone.

The dimethylsiloxane co-units dilute Si–H site density relative to LF-H101H (high-hydrogen PMHS), providing controlled, lower crosslink density upon cure — producing softer, more flexible elastomeric networks and reducing steric hindrance during hydrosilylation grafting of bulky organic side chains.

Viscosity (10–1,000 mPa·s) and hydrogen content (0.1–1.5 wt%) are independently customizable, allowing precise tuning of crosslink density, cure kinetics, and chain flexibility for specific formulation requirements.

Applications of Low Hydrogen Silicone Fluid LF-H101L

Controlled Crosslinker for Soft LSR and Silicone Encapsulants
Used as crosslinking agent in platinum-catalyzed addition-cure LSR and silicone encapsulant systems where reduced crosslink density is required to achieve higher elongation at break, lower hardness (Shore A), and improved tear strength compared to systems crosslinked with high-hydrogen PMHS. Si–H to vinyl ratio and hydrogen content selection determine the mechanical profile of the cured elastomer. Avoid contact with Pt catalyst inhibitors (sulfur, phosphorus, tin compounds, amines).
Synthetic Intermediate for Modified Silicone Fluids
Used as Si–H reactive backbone for synthesizing polyether-modified, epoxy-modified, and long-chain alkyl-modified silicone fluids via Pt-catalyzed hydrosilylation. Lower Si–H density reduces inter-site steric interference during grafting of bulky side chains (e.g., polyether or long alkyl groups), improving grafting efficiency and product uniformity relative to high-hydrogen PMHS.
Dry Powder Anti-Caking Treatment
Used as moisture-proof, anti-caking surface coating for dry chemical fire extinguishing powders. Controlled Si–H content provides sufficient surface hydrophobing while the copolymer backbone imparts flexibility to the treated powder particle coating, maintaining flowability and discharge performance under long-term storage.
Hydrophobing Agent for Construction and Industrial Substrates
Applied neat or in dilute solution to glass, ceramics, cement, marble, metals, and leather. Dehydrogenative condensation with surface hydroxyl groups under acid or metal salt catalysis deposits a hydrophobic siloxane film. Lower crosslink density of LF-H101L-derived films provides a more flexible coating layer suited to substrates that undergo dimensional change or flex in service. Ensure adequate ventilation — hydrogen gas is released during condensation with hydroxyl surfaces.

Package & Storage of Low Hydrogen Silicone Fluid LF-H101L

In 50kg, 200kg drum and 1000kg IBC.
Keep in cool, dry and ventilated place. Keep away from sunlight and fire sources. Keep in unopened containers, shelf life is 12 months from the date of production. It is shipped as non-hazardous substance.
Storage beyond the shelf life does not necessarily mean that the product is no longer usable. In this case however, the properties required for the intended use must be checked for quality assurance reasons.
