SS-27 Product Description
Download PDF
SS-27 is an electrically conductive, moisture curing silicone RTV. SS-27 is
a 1-Part silicone that when applied to the substrate allows handling of the
assembly within an hour. When cured, the elastomer resists weathering, ozone,
moisture, UV and high temperatures. SS-27 works well in manual and automatic
dispensing equipment.

Method of Application
Dispense sealant onto part. Mate parts, ensuring not all of the product is
squeezed out of flange assembly. Allow to cure.
Chemical cure system
Oxime cure system
Solids
98% solids, contains no solvents
Curing
Cure speed can be accelerated with increased humidity 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.
Adhesion
Primerless adhesion to most plastics, metals and typical substrates.
Limitations
Do not use product in solvent or fuel immersion applications. Allow to fully
cure before putting assembly into service. Ensure enough product remains between
flanges to be effective in an assembly.
Packaging
SS-27 is available in 10.3 oz. cartridges and 40 lb. pails. This product is
also available in customer defined packaging sizes, upon request.
Handling and safety
For maximum shelf life, keep containers sealed when not in use. Keep out of
the reach of children. Uncured sealant can irritate eyes and skin. Refer to
MSDS.
Shelf-life
Sealed containers are guaranteed for 1 year from the ship date when stored
in a cool dry area below 70 F.
