New Black Epoxy Potting Compounds
Techsil introduces 2 new black encapsulation resins- MG 832FX and MG 832HD for PCB potting, manufactured by MG Chemicals. These epoxies due to their low viscosity can easily penetrate small gaps and cavities. They also provide excellent electrical insulation and protect components from-
  • Electrostatic Discharges (ESD)
  • Vibration 
  • Abrasion
  • Thermal Shock 
  • Environmental Humidity 
  • Salt Water 
  • Fungus and 
  • Many Harsh Chemicals…. 

Key Features of Two New Black Epoxy Potting Compounds

The 2 New Black Encapsulation Resins are- MG 832FX and MG 832HD

  • MG 832FX- It is flexible like silicone but with the Durability and Cost-effectiveness of Epoxy. It forms a tough bond that flexes to provide impact and vibration resistance and offer excellent physical, chemical, and electrical protection. This Epoxy is particularly effective where severe thermal shocks occur in the components' environment or where devices are in a submersion state.

  • It is designed for applications where minimizing the physical stress on components is critical. Classed as a ‘low temperature epoxy’, it is also good in arctic environments, as well as applications that involve temperature cycling or rapid temperature changes.

  • MG 832HD- An economical, general purpose, flowable, electronic-grade black potting epoxy that provides extreme environmental, chemical, and physical protection for circuit boards and electronic assemblies.

  • It is Harder than most Epoxies to give Extreme Protection. The hard shell (harder than standard black epoxy resins) provides greater protection against extreme impacts and vibrations. It has excellent electrical insulating characteristics, a broad service temperature range of -40 to 140 °C and adheres to most substrates including metals, composites, glass, ceramics and many plastics.

Epoxies Developed for Various Fields

These epoxies have a convenient 1:1 volume mix ratio, making them compatible with most dispensing equipment. They can be cured at room temperature or higher and are available in dual cartridge format. Being black in colour means that they help to restrict access to proprietary electronics and hide electrical circuit designs.

They are developed for use in different fields like-
  • Manufacture of printed circuit boards (PCBs)
  • Electronic devices and
  • Many Types of Electrical Assemblies like protection, impact protection, environmental protection, chemical protection or to protect your intellectual property.

These two new black potting compounds can deliver a robust solution.
