160 Liquid Grey Silicone Encapsulants Potting Compound For LED Solar Cell Circuits
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.
