Product Overview
Terminal alkoxysilane groups hydrolyze and condense on exposure to moisture to form a crosslinked siloxane network. The TDS describes one- and two-component formulation routes.
Key Features
- Base polymer for moisture-curing elastic sealing.
- High-modulus formulation direction.
- Can be formulated without solvents or free isocyanates.
Physical Properties
| Property | Reported value |
|---|---|
| Viscosity (25°C) | 7,000–10,000 mPa·s |
| Flash point | Above 237°C |
Selected values from the original TDS. Refer to that document for conditions and whether values are typical or specification limits.
Typical Applications
- Moisture-curing elastic sealant for construction glass-to-metal joints.
Technical Considerations
Use as a base polymer in a qualified complete formulation; control moisture exposure during storage and processing. Final adhesion, modulus and curing must be verified for the substrate and joint design. Typical values are not specifications; consult the SDS.
