SUMMARY

The discussion centers on the search for an electrically inert adhesive that is both strong and easy to apply. United Resin F-82 epoxy is highlighted as a suitable option for potting electronic components due to its durability and compatibility with electronics. While Electronics grade RTV is mentioned, it lacks the strength required for demanding applications. Important considerations for reliability in electronic assemblies are also noted, emphasizing the need for careful application.

PREREQUISITES
  • Understanding of epoxy and adhesive properties
  • Familiarity with electronic component potting techniques
  • Knowledge of electrical conductivity and its implications for circuit integrity
  • Basic skills in applying adhesives safely and effectively
NEXT STEPS
  • Research the specifications and applications of United Resin F-82 epoxy
  • Explore the properties and limitations of Electronics grade RTV
  • Learn about best practices for potting electronic assemblies
  • Investigate alternative electrically inert adhesives suitable for electronics
USEFUL FOR

Electronics engineers, product designers, and technicians involved in the assembly and protection of electronic components will benefit from this discussion.

Hi I'm looking for a super glue/epoxy that meets the following requirements:

1) when hardens is very very strong and durable and very resistance to abuse either mechanically or chemically etc

2) needs to be electrically inert, meaning that it should not be conductive or affect electronic circuitry in any way when applied on top of it, i.e. trace wires or chips etc...

3) be relatively easy and safe to apply


So does such a wonder glue exist?

Thanks

Electronics grade RTV is used commonly, but it is not all that strong.

We use United Resin F-82 epoxy for potting some of our products. It is quite hard and strong, and is compatible with electronics applications:

However, if you are potting electronics assemblies or components, there are some *very* important considerations, in order to avoid some reliability problems. Can you say more about the application?
