A common problem associated with the production of electrical potting compounds is the formation of CO2 bubbles within the formula. These bubbles look unattractive, and they also lower the strength of the potting compound, which can lead to electrical component failure – as a result of moisture ingress.
To solve this issue, producers of electrical potting compounds typically use a Zeolite Powder such as 3A SUPERSIV, to absorb any water that may be present in the Isocyanate or Polyol components. Once this water has been removed, the remaining reactants will bond with each other, to form a bubble-free compound.
For those manufacturers who don’t own the processing equipment required for the dispersion of fine powders into liquids, there is an alternative product which they can use, this is called 3A SUPERSIV Paste. This product is a pre-blended and viscose liquid, that chemists can just pour-in to their formulation. It’s simple to use, and it mixes into polymers with create ease.
