Product Description
Momentive RTV31 is high-temperature two-part silicone elastomer. It is supplied ready-to-use with a base compound and dibutyl tin dilaurate (DBT) as the standard curing agent. While DBT is generally appropriate for most applications, alternative catalysts are available to facilitate deep section cure, faster cure and automated mixing.
The series includes RTV31, RTV60, RTV88. They differ primarily in viscosity in the uncured state.
Key features and benefits of Momentive RTV31
- Variable work times and cure rates (via adjusting the amount and type of curing agent)
- Room temperature cure
- Solvent-less formulation (no solvent odor)
- Excellent adhesion capabilities with primer
- Excellent release properties
- Retention of elastomeric properties at temperatures from -54°C (-65°F) up to 260°C (500°F) continuously; up to 316°C (600°F) for short periods of time
Applications of Momentive RTV31
- Potting and encapsulating electric motors and transformers
