Features
Chemical Name: Hydrogen-Terminated Polydimethylsiloxane
Abbreviations: H-Terminated PDMS, Hydride-Functional Silicone Oil
Appearance: Colorless to pale yellow liquid
Odor: Mild characteristic silicone odor
Viscosity: Low to medium, depending on molecular weight
Solubility: Insoluble in water; soluble in organic solvents
Flammability: Flammable; reacts with moisture and acids to release hydrogen
Handling
1. Flammable and reactive — handle away from heat, sparks, open flames, and hot surfaces.
2. Avoid breathing vapors or mist.
3. Avoid contact with skin, eyes, and clothing.
4. Use in well-ventilated areas with local exhaust ventilation.
5. Wear appropriate PPE: chemical-resistant gloves, safety goggles/face shield, and protective clothing.
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. Avoid contact with acids, strong oxidizing agents, and moisture, as reactions may release hydrogen gas.
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 acids, strong oxidizers, and moisture.
5. Use containers suitable for flammable and reactive liquids.
6. Follow local regulations for storage of flammable and moisture-sensitive chemicals.
1. Crosslinker in Addition-Cure Silicone Systems
H-PDMS reacts with vinyl-functional polysiloxanes in the presence of platinum catalysts to form elastomeric networks.
Used in:
RTV-2 silicone rubber
Liquid Silicone Rubber (LSR)
High-temperature vulcanized (HTV) silicone
