Technical Data Sheet
Silicone Rubber Compounds for High Temperature
Product Description
RTV31, RTV60 and RTV88 silicone rubber compounds are high
temperature two-part silicone elastomers. They are supplied ready-to-use
with a base compound and DBT (dibutyl tin dilaurate) as the standard
curing agent. DBT is suitable for most applications, however other
catalysts are available to facilitate deep section cure, faster cure and
automated mixing.
RTV31, RTV60 and RTV88 silicone rubber compounds differ primarily in
viscosity in the uncured state.
Key Performance
Properties
• Variable work times and cure rates by adjusting the amount and
type of curing agent
• Room temperature cure
• Composition free of solvents and solvent odour
• Excellent adhesion capabilities with primer
• Excellent release properties
• Retention of elastomeric properties at temperatures from -54°C
up to 260°C continuously, and up to 316°C for short periods of
time
•
Applications
Typical high temperature applications for these products include, but are
not limited to:
• Potting and encapsulating electric motors and transformers
• Fabrication of rubber parts
• Casting moulds for low-melting point metals
• Release applications such as rubber rollers
• Thermal insulation

Bonding
If adhesion is an important application requirement, RTV31, RTV60 and
RTV88 silicone rubber compounds require a primer to bond to non-
silicone surfaces. Thoroughly clean the substrate with a non-oily solvent
such as naphtha or methyl ethyl ketone (MEK) and let dry. Then apply a
uniform thin film of a suitable silicone primer such as SS4004P and
SS4155 silicone primer and allow the primer to air dry for one hour or
more. Finally, apply freshly catalyzed RTV silicone rubber compound to
the primed surface and cure as recommended.
Handling and
Safety
Material Safety Data Sheets are available upon request from Momentive
performance materials. Similar information for solvents and other
chemicals used with the Momentive performance materials products
should be obtained from your supplier. When solvents are used, proper
safety precautions must be observed.
Storage and
Warranty Period
The warranted shelf life will be indicated by the ' use before date' on the
associated documents with a minimum of 4 months when stored in the
original unopened containers at following temperatures :
RTV 31 and RTV 60 : 2 – 10 °C
RTV88 : < -18 °C
Availability
RTV31/60/88 are available in 227 kg drums for which the catalyst needed
has to be ordered separately. Further in 450 g, 5.5 kg and 23 kg
containers all supplied with the DBT amount needed to catalyze the
material. If other catalysts are desired for a specific application this
should be ordered separately.
