Methyl hydrogen silicone fluid is offered as a multi-grade product series rather than a single fixed specification. The range includes standard methyl hydrogen silicone fluid, low hydrogen silicone fluid, and hydrogen-terminated silicone fluid grades to support different formulation and processing requirements.

Grade selection is primarily based on hydrogen content, viscosity, solid content, and whether terminal hydrogen functionality is required. The 1-000 series covers standard methyl hydrogen grades, the 1-100 series provides lower-hydrogen options across multiple viscosity ranges, and the 1-200 series provides hydrogen-terminated grades.

Refer to the Technical Specifications table below to compare individual models and confirm final suitability through testing in the intended formulation or production process.

It is colorless and odorless with the properties of weather resistance and hydrophobicity. The Si-H bonds it contains can crosslink into waterproof films or react with substances containing double bonds, hydroxyl groups, or other functional groups, thereby generating silicone products with diverse specialized properties.

It is widely used as:
1. Additive for water-resistant gypsum boards and advanced waterproofing materials;
2. Crosslinking agent for addition-cure silicone rubber products;
3. Moisture-proof/waterproofing agent for fire-extinguishing powder, glass, ceramics, and marble;
4.Water-repellent finishing agent for textiles;
5. Key raw material for modified silicone oil synthesis;
6. Hydrophobic agent, lubricant, and anti-adhesive in cosmetic oil-based foundations.

Equivalent to Dow MHX-1107.

Key Features

Reactive Si–H Functionality

The Si–H bonds in selected methyl hydrogen and hydrogen-terminated silicone fluid grades can participate in compatible crosslinking or modification reactions. Under suitable processing conditions, they can react with materials containing double bonds, hydroxyl groups, or similar functional groups.

This reactivity supports their use in addition-cure silicone rubber systems, modified silicone oil synthesis, and other compatible silicone-material applications.

Water Repellency and Film Formation

Methyl hydrogen silicone fluid grades in the 1-000 series are described as colorless and odorless, with weather-resistance and hydrophobic properties. Their reactive Si–H functionality can support the formation of water-repellent films on suitable substrates.

Suitable grades can be considered for textile finishing, waterproof gypsum-board additives, advanced waterproofing materials, and compatible treatment systems for glass, ceramics, marble, and fire-extinguishing powder.

Multiple Hydrogen Content and Viscosity Options

The series provides high-, low-, and terminal-hydrogen options with different viscosity and solid-content ranges. This allows formulators to select a grade according to the required reaction activity, processing conditions, and performance target.

Final compatibility, dosage, reaction conditions, and finished-product performance should be verified in the intended formulation before commercial production.

Applications and Formulation Notes

Water-Repellent Treatments and Waterproofing Materials

Methyl hydrogen silicone fluid can be used in compatible water-repellent treatment systems for textiles, gypsum boards, fire-extinguishing powder, glass, ceramics, marble, and other suitable substrates.

Its reactive Si–H functionality can support the formation of a water-repellent film under appropriate application conditions. Evaluate substrate compatibility, water repellency, appearance, and durability in the final application before production-scale use.

Silicone Rubber Crosslinking and Modified Silicone Oil Synthesis

Selected grades can be used as crosslinking agents in compatible addition-cure silicone rubber systems. Hydrogen-terminated silicone fluid can react with compatible substances containing double bonds, hydroxyl groups, or similar functional groups under suitable catalytic conditions.

These materials can also be used as raw materials for modified silicone oil synthesis. Confirm the reaction mechanism, catalyst system, viscosity, hydrogen-content requirement, and finished-product properties before scale-up.

Oil-Based Foundation Formulations

According to the current product information, suitable methyl hydrogen silicone fluid grades can be considered as hydrophobic additives, lubricants, and anti-adhesive components in compatible oil-based foundation formulations.

Finished-product stability, sensory performance, ingredient compatibility, and applicable market-compliance requirements should be verified before product launch.

Packaging, Storage & Handling

Packaging Options

Methyl hydrogen silicone fluid is available in 200 L plastic drums, 200 L plastic-coated iron drums, and 1,000 L IBC containers to meet different commercial procurement and production requirements.
