Sodium Stearate - an overview | ScienceDirect Topics

It has good electrical and heat insulation properties and dimensional stability. It docs not wet well and sticks in the mold; it needs to be used with a wetting agent such as sodium stearate, sodium lauryl sulfate, sodium lignin sulfonate, or silicone coupling agents. The wetting agent reduces interfacial tension between filler and resin.
