Handling

1. Avoid breathing vapors or mist.

2. Avoid contact with skin, eyes, and clothing.

3. Use only in well-ventilated areas or with local exhaust ventilation.

4. Wear appropriate PPE: chemical-resistant gloves, safety goggles/face shield, and protective clothing.

5. Flammable material — keep away from heat, sparks, open flames, and hot surfaces.

6. Ground and bond containers during transfer to prevent static discharge.

7. Do not eat, drink, or smoke while handling.

8. Wash thoroughly after handling.

9. Keep away from strong oxidizing agents, acids, and moisture.

Storage

1. Store in a cool, dry, well-ventilated area.

2. Keep container tightly closed when not in use.

3. Protect from heat, direct sunlight, and ignition sources.

4. Store away from oxidizing agents, acids, and moisture.

5. Use approved containers suitable for flammable silicone fluids.

APPLICATION SCENARIOS

1. Crosslinking Agent in Silicone Elastomers (Primary Application)

MH Fluid functions as a hydrosilylation crosslinker in platinum-catalyzed addition-cure systems, including:

RTV silicone rubber

HTV silicone rubber

Liquid silicone rubber (LSR)

It reacts with vinyl-functional polysiloxanes to form three-dimensional elastomer networks with controlled crosslink density and mechanical properties.

2. Water-Repellent and Hydrophobic Treatment

Used for surface treatment of:

Concrete

Masonry

Gypsum

Natural stone

Textiles

Si–H groups react with surface hydroxyl groups to form durable hydrophobic siloxane layers, improving water resistance while maintaining substrate breathability.

3. Silicone Emulsions and Textile Finishing

Applied in:

Fabric water repellents

Soft finishing agents

Anti-sticking treatments

Provides durable hydrophobicity and improved surface feel.

4. Release Agents and Anti-Adhesion Systems

MH Fluid is incorporated into:

Mold release formulations

Rubber and plastic processing aids

Paper release coatings

It enhances release efficiency and surface lubrication.

5. Reactive Intermediate in Silicone Modification

Used in hydrosilylation reactions to synthesize:

Functionalized polysiloxanes

Modified silicone resins

Silicone surfactants

Specialty organosilicon intermediates
