Liquid Grey Silicone Encapsulants Potting Compound Silicone
Description
MC-RTV160 Silicone compound is supplied as a two-component addition
cure system. It consists of Part A and Part B. The component A is
grey and component B is white for easy identification and
inspection of complete mixing.(colors can be adjusted as per
customer requirement.) When the components are thoroughly mixed in
a 1:1 ratio by weight or volume, the liquid mixture cures to a
flexible elastomer, which is suited for electrical/electronic
potting and encapsulating applications.
Applications
MC-RTV160 Silicone Compound is a general purpose compound suited
for adhesive and coating. This cost-effective silicone can be used
in a variety of electronic potting applications including the
adhesive and coating for solar power, HID, LCD displayers, circuit
board and electronic components, etc.

Features
Silicone compound has a excellent electrical property features in
resistant to temperature, corrosion, radiation, insulation,
waterproof, damp proofing, shock resistance, thermal conducting,
inflaming retarding and weather ability, etc. It can be long-term
used under -50℃～200℃.
Thermal expansion properties
The coefficient of thermal expansion ranging of silicone compound
is 5.9-7.9 x 10-4/°C. The coefficient of linear thermal expansion
is about 1/3 of the coefficient of volume thermal expansion; it can
be used for the overall linear thermal expansion calculation of
rubber parts under a certain limits of temperature.
Using Instructions
Silicone compound part A and Part B should be thoroughly mixed at a
1:1 ratio (weight or volume) before using. Pour into the electronic
components after vacuum de-airing. Silicone compound may be cured
at room temperature or accelerated with heat.
Packing and Storage
- Silicone rubber is shipped as kits that Part A and B liquid
components in separate containers. It is available in packing in
5kg or 20kg,200kg per pail.
- Silicone rubber must be tightly sealed in cool and dry place,
prevented from sun and rain. Transport by non-dangerous goods.
