We have been unable to prevent the formation of microfoam in anti-corrosive systems with conventional silicabased thickening agents, nor with cellulose derivatives. What would you advise us to do?
The obvious solution would seem to be use bentonites, i.e. layer-lattice silicates of the montmorillonite type, organically modified. These products impart an easily controllable degree of thixotropy which can be adjusted so that perfect flow is achieved on the one hand, and on the other that decaration can proceed unhindered. The decisive factor here is that the sodium ions which are loosely bound to the layer crystals can be replaced by organic radicals of varying length and structure (in line with the film-forming substance).
