832C
Translucent Epoxy
Encapsulating & Potting Compound
832C Technical Data Sheet
Description
The 832C Translucent Epoxy Encapsulating and Potting Compound is an electric grade epoxy. It is simple
to mix and easy to use. This two parts clear epoxy provides great insulation and protection value.
It protects against static discharges, shocks, vibrations, and mechanical impacts. It insulates against heat
and conductivity. It is extremely resistant to environmental humidity, salt water, and many harsh
chemicals.
Applications & Usages
The 832C epoxy is used to pot or encapsulate printed circuit assemblies in protective blocks. The cured
epoxy improves reliability, operational range, and lengthens the life of electrical and electronic parts.
Its primary applications are in the automobile, marine, aerospace, aviation, communication,
instrumentation, and industrial control equipment.
Benefits
Extreme impact resistance (contains a form of nylon)
Extreme resistance to water and humidity allowing submersion if needed
Strong chemical resistance to brine, acids, bases, and aliphatic hydrocarbons
Good protection of electronics against corrosion, fungus, thermal shock, and static discharges
Easy 2A:1B mix ratio compatible with most dispensing equipment
Negligible Volatile Organic Content (VOC)
