SS-3146 Product Description
Download PDF
SS-3146 is a high strength, neutral curing silicone RTV adhesive rubber. This
product was developed for applications requiring fast development of physical
properties and fast unprimed adhesion. SS-3146 is a 1-Part silicone that allows
handling of the bonded assembly within one hour of application to the substrate.
When cured, the elastomer resists weathering, ozone, moisture, UV and high
temperatures. SS-3146 works well in manual and automatic dispensing equipment.

Method of Application
Dispense sealant onto part and mate parts. Do not squeeze all of the product
out of flange assembly. Allow to cure.
Curing
Cure speed can be accelerated with increased humidity to very rapid cures
exhibiting surprisingly fast adhesion. Typical utilization involves dispensing
in open air with exposure to ambient humidity. This method of application
will result in a room temperature cured elastomer with very high adhesive
properties.
Chemical cure system
Oxime cure system
Solids
98% solids, contains no solvents
Adhesion
Primerless adhesion to most plastics, metals and glass
Service temperature
-65 to 260C
Limitations
Do not use product on head gaskets, 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-3146 is available in 10.3 oz. cartridges, 50 lb. pails and 500 lb. drums.
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 irritates 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.
