SS-69 Product Description
Download PDF
SS-69 is a high strength, high temperature silicone RTV
engineered for applications requiring fast development
of physical properties and excellent adhesion. SS-69 offers the highest temperature resistance of any acetoxy cure silicone currently available. When cured, the elastomers resist weathering, ozone, moisture,
UV and high temperatures. SS-69 work well in manual and automatic
dispensing equipment.
Product Features
Fast R.T. cure
Thixotropic paste
Excellent unprimed adhesion to plastic, metal and glass
Convenient, Heat Accelerated
Instant Cure Capability
Typical Applications
Assembly line adhesive
Form in place gaskets
Adhesive Sealant
Heat Accelerated Curing
Typical utilization involves dispensing in open air and ambient humidity to
result in a high strength adhesive rubber. However, cure speed can be accelerated
with hot air to nearly instant cures exhibiting very fast adhesion. A one
minute hot air stream exposure, followed by a one minute cool down in a humid
environment, results in cured elastomer condition exhibiting outstanding adhesion.
Method of Application
Dispense dressing onto gasket and flange surface. Install component and tighten
fasteners to the manufacturer’s torque specifications, thus sealing
all surface irregularities with the fastener clamping force.
Chemical cure system
Acetoxy cure system

Method of Application
Dispense sealant onto part and mate parts. Do not squeeze all of the product
out of flange assembly. Allow to cure.
Chemical cure system
Acetoxy cure system
Solids
98% solids, contains no solvents
Adhesion
Primerless adhesion to most plastics, metals and typical substrates.
Limitations
Do not use product on head gaskets, fuel or solvent immersion applications.
Allow sealant to fully cure before putting assembly into service. Ensure enough
product remains between flanges to be effective in an assembly.
Packaging
SS-69 is available in 10.3 oz. cartridges, 40 lb. pails and 400
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.
Applicable standards
