107 High Viscosity Silicone Rubber
107 High-Viscosity Methyl Silicone Rubber, also known as Room Temperature Vulcanized Silicone Rubber (RTV-107/OH Polymer), is a silicone polymer with terminal hydroxyl groups. Its chemical name is α,ω-dihydroxy polydimethylsiloxane. This colorless, transparent, viscous liquid reacts with cross-linking agents and catalysts at room temperature, making it an ideal base polymer for silicone rubber.
Viscosity Classification:
- Low-viscosity silicone rubber： 350-1100 mPa·s
- Medium-viscosity silicone rubber: 2500-80,000 mPa·s
- High-viscosity silicone rubber: Above 80,000 mPa·s
Widely used in industrial molding, coatings, adhesives, and sealants, RTV-107 offers excellent durability, flexibility, and chemical resistance, making it ideal for high-performance silicone applications.

| Storage | storage at ventilating and dry place and prevention from water, heat and fire |
| Shelf Life | 24 Months |
| Usage | 1. Normally it is used with addition of curing agent for cross-linking and curing. When used in treatment of anti-stick paper, coupling agent should be added.
2. Normally content of curing agent is 3~5% of basic gum. Content of coupling agent is 0.5~1% of basic gum. 3. It is recommended to dilute the basic gum to 10 times of original volume before adding the curing agent or coupling agent. Agitate until uniform before coating on the substrate surface. The curing reaction typically performed at normal or elevated temperature. Curing needs more than 30 min under normal room temperature and 30 sec if temperature is between 120℃~150℃. 4. Solvent-free for sealant and mould basic gum. After adding curing agent, agitate un |
