RTV 2 Transparent Electronic Silicone Potting Compound For LED
Lights
Description of RTV 2 Transparent Electronic Silicone Potting Compound For LED
Lights
Silicone MCSIL-E184 is supplied as a two-component 10 to 1 liquid
silicone addition cure system. It consists of Part A and Part B.
When two components are thoroughly mixed, the mixture cures to a
flexible elastomer, which is well suited for the protection of
electrical/electronic applications.

Preparing Surfaces
In applications requiring adhesion, priming will be required for
many of the silicone encapsulants. For best results, the primer
should be applied in a very thin, uniform coating and then wiped
off after application. After application, it should be thoroughly
cured prior to application of the silicone elastomer.
Processing & Curing
MC Silicone E184 part A and Part B should be thoroughly mixed at a
10:1 ratio , may be poured/dispensed directly into the container in
which it is to be cured. Care should be taken to minimize air
entrapment. When practical, pouring/dispensing should be done under
vacuum, particularly if the component being potted or encapsulated
has many small voids. If this technique cannot be used, the unit
should be evacuated after the silicone encapsulant has been
poured/dispensed. MC silicone encapsulants may be either room
temperature (25°C/77°F) or heat cured. Room temperature cure
encapsulants may also be heat accelerated for faster cure. Ideal
cure conditions for each product are given in the product selection
table.
Pot life and curing rate of RTV 2 Transparent Electronic Silicone Potting Compound For LED
Lights
Cure reaction begins with the mixing process. Initially, cure is
evidenced by a gradual increase in viscosity, followed by gelation
and conversion to a solid elastomer. Pot life is defined as the
time required for viscosity to double after base and curing agent
are mixed and is highly temperature and application dependent.
Please refer to the data table.
Useful Temperature Ranges
For most uses, silicone elastomers should be operational over a
temperature range of -45 to 200°C (-49 to 392°F) for long periods
of time. However, at both the low and high temperature ends of the
spectrum, behavior of the materials and performance in particular
applications can become more complex and require additional
considerations and should be adequately tested for the particular
end-use environment.
