Flowsil
is a flowable self levelling RTV silicone sealant
which cures at room temperature in reaction with moisture
to form a tough but flexible silicone rubber. Unlike
many other RTV's this product does not give off any
acid and is therefore safe to use in electronics and
applications where non corrosion of
the substrate is paramount. A further benefit of this
is that there is no offensive vinegar like odour.
Industrial applications include:
Bonding,
sealing, insulating and Coating electronic components,
copper coils & bare wires
High
temperature adhesive applications especially when bonding
materials with different CTE rates
Making
temperature, vibration and chemical resistant seals
/ gaskets
High
temperature sealing in air ducting and flexible hosing
Flowsil
is one of the few adhesives which will stick silicone
rubber, use it for bonding silicone gaskets and end
caps in place. Repairing splits in moulding rubber and
making O rings with silicone rubber strip

Adhesion
Flowsil
bonds well to glass,silicone rubber, metals including
copper & aluminium and most rigid plastics. Primers
are available for maximum adhesion on more difficult
substrates such as stainless steel.
Flowsil
is not suitable for bonding PTFE, polyethelene,
polypropylene, plasticised PVC . Please contact our
technical department for further information.

tolerance to alkalis, mineral oils, ethyl alchohol,
dilute acids, boiling water, ozone and UV light.
Incidental
contact with fuels is acceptable but not recommended
for continuous immersion.
