Momentive Red High Temperature Flowable Sealant

The Momentive RTV31 is a high-temperature two-part silicone elastomers. 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 three silicone elastomers differ primarily in viscosity in the uncured state. RTV31 and RTV60 are flowable sealants; RTV88 is a paste sealant.

Potential Applications

Typical high temperature applications for these products include, but are not limited to:

• Potting and encapsulating electric motors and transformers
• Fabricating rubber parts
• Casting molds for low-melting point metals
• Release applications such as rubber rollers
• Thermal insulation
