What does RTV mean?
Despite the low-temperature connotations conveyed by this
name, RTV silicones consist of both Room Temperture Cure and
Heat Cure grades.
What is the cure mechanism of a condensation cure
product?
atmospheric moisture. Moisture in the air is generally required to
cure (or vulcanize) condensation cure products. The cure process
begins from the outer surface, and therefore time is required
for complete cure. The cure time is affected by the reaction
mechanism and viscosity of the material. Generally, at 25C and
50%RH, condensation cure RTV silicones cure through in 24 to 48
hours. Full physical properties may take up to 7 days to develop.
What is the depth (bead thickness) limitation for a
condensation cure grade?
thickness) limitation is approximately 6mm (1/4"). For 2-part,
condensation cure products, the depth (bead thickness)
limitation is approximately 25mm (1").
Can I accelerate the cure time of a 1-part product?
silicone thickness, and to a smaller degree heat. Increasing the
relative humidity around the silicone or reducing the thickness of
the material will reduce the time to cure the material. Increased
heat (not over 50C) will somewhat reduce cure time but as
mentioned will do so to a much smaller degree than humidity or
thickness.
What is the cure mechanism of an addition cure product?
cure when exposed to heat. Although some heat cure products
can cure at room temperature, higher heat greatly accelerates
the cure. 1-part heat cure products typically have an inhibitor
in the formulation that stops the product from curing until an
activation temperature, greater than room temperature, is
achieved and the inhibitor is driven off and the cure reaction is
allowed to proceed.
What does "tack free time" mean?
condensation cure silicone product to form a cured outer layer
(the cured outer layer is not tacky like uncured material).
What is "mix ratio"?
to be in a multi-component material. The mix ratios for 2-part
products are described on the individual product data sheets
and are given as a ratio by weight of each material.
What does "pot life" or "work life" mean?
curing agent that it will remain useful or pliable.

uncured paste. Wipe the area clean with isopropyl alcohol to
remove any leftover residue. After it is cured: First mechanically
remove as much of the silicone as you can with either a knife
or a razor. A solvent (mineral spirits, toluene, xylene, acetone)
can them be used to remove any oily residue or any remaining
silicone, It may be necessary to soak the silicone in a solvent
overnight to break it down.
Can I thin a silicone?
is miscible, generally an aromatic solvent such as toluene or
xylene. As always, be sure to follow the producer's instructions
when using solvent products and always use in a well-ventilated
area. The shrinkage of the silicone and the cure time will increase
with the addition of solvent. Alternative suggestions would
include non-reactive fluids or an RTV with a lower viscosity.
What can I do to improve the adhesion of the silicone
adhesive to my parts?
the silicone to bond to. For difficult-to-bond-substrates, GE -
Advanced Materials, Silicones offers a number of primers that
can be used to improve and maximize adhesion.
How do I ensure that air is removed from 2-part grades?
during the mixing process. Vacuum de-airing is most effective
in removing air prior to use. Automated mixing equipment that
utilizes a static mixer can eliminate the need to de-air prior to
dispensing.
trapped under components during the potting process. Where
this is a concern, potting under vacuum or vacuum de-airing
after potting can remove the trapped air. An alternate approach
may be to use a grade with a low viscosity and longer potlife
and to cure at lower temperatures (if heat-cure grade), allowing
entrapped air to escape prior to the cure of the material.
What is cure inhibition, and how do I prevent it?
addition-cure grades. These materials use a platinum catalyst
to drive the curing reaction. Surfaces containing water, sulphur,
nitrogen compounds, organic metal compounds, or phosphate
compounds, may inhibit cure.
appearance of the silicone at the interface between the silicone
and offending substrate. Inhibition can be prevented by
application of a barrier coat, cleaning of the offending material
prior to application of the silicone material, replacing the
offending material with a suitable alternative, or selection of a
condensation cure grade.
Before it is cured: use a putty knife to remove any of the
