Abstract: Electronic devices protected by an organic polymeric encapsulant and placed in a corrosive environment can have added protection by dispersing in the encapsulant particles of a solid buffer which tend to neutralize the effect of the corrosive agent. This approach is quite effective when strong acids are the corrosive agents, and when solid acid-base buffers are dispersed in the polymeric material. The encapsulant may be elastomeric, and silicone elastomers containing solid acid-base buffers are quite effective in protecting the underlying electronic device from corrosion by strong acids.
