SS-25 Product Description
SS-25 is an electrically conductive, moisture curing silicone RTV. SS-25
is a 1-Part silicone that when applied to the substrate allows handling of
the assembly after 1 hour. When cured, the elastomer resists weathering, ozone,
moisture, UV and high temperature. SS-25 works well in manual and automatic
dispensing equipment.

Method of Application
Dispense sealant onto part. Mate parts, and be sure not to squeeze all of
the product out of flange assembly. Allow to cure.
Chemical cure system
Oxime cure system
Curing
Cure speed can be accelerated with increased humidity and heat to very rapid
cure times. Typical utilization involves dispensing in open air and after
exposure to ambient humidity, a room temperature cured rubber with electrically
conductive properties is formed.
Packaging
SS-25 is available in 10.3 oz. cartridges and 70 lb. pails. This product is
also available in customer defined packaging sizes upon request.
Solids
98% solids
Adhesion
Primerless adhesion to most metals and typical substrates.
Service temperature
-65 to 260C
Limitations
Allow to fully cure before putting assembly into service. Ensure enough product
remains between flanges to be effective in an assembly.
Handling and safety
For maximum shelf life, keep containers sealed when not in use. Keep out of
the reach of children. Uncured sealant irritates eyes and skin. Refer to MSDS.
Shelf-life
Sealed containers are guaranteed for 6 months from the ship date when stored
in a cool dry area below 70 F.
