Various embodiments of the teachings herein include an apparatus for voltage equalization in square-wave voltages of electric motors. The apparatus may include: a terminal board circuit wherein phases U, V, and W each comprises input and output cabled conductors summing to at least 6 cables; and a bridge between two of the at least six cables connecting two or more of the at least 6 cable inputs and outputs. The bridge is partially conductive such that its electrical resistance markedly reduces above a threshold value. The partial conductivity results from filler particles in an embedding matrix determining a reduction of the resistance in the bridge above the threshold value.

A one-part primer composition is provided. The one-part primer composition includes a first epoxy resin that is a liquid under ambient conditions a particulate corrosion inhibitor present in an amount of from 5 wt % to 30 wt % relative to the overall weight of the composition excluding carrier solvents and water, a curative comprising a primary aromatic amine, a silane coupling agent, a carrier solvent; and water homogeneously mixed with the carrier solvent and present in an amount sufficient to hydrolyze the silane coupling agent while preserving solubility of the first epoxy resin and curative in the carrier solvent/water mixture. The corrosion inhibitor is pre-dispersed in a liquid epoxy to break the agglomeration of the inhibitors, mitigate settling of the pigment and improve primer performance.

A filler for wall coating compositions, wherein said filler consists of particles, wherein said particles are fired mixtures of 40 to 70% by weight of clay minerals 5 to 32% by weight of crystalline silicic acids 10 to 45% by weight of feldspar 0 to 20% by weight of other aggregates,
and wherein said particles have a d50 grain size of from 1 μm to 40 μm.
