Walker Emulsions Limited

Purpose

The gypsum industry uses polysiloxanes or paraffin wax to impart water resistance to their products. These additives are highly effective in providing water-resistance but have limitations. For example, polysiloxanes are subject to regulatory pressures. Conversely, paraffin wax dispersions suffer from relatively high cost as they are manufactured and transported at relatively low solids content. We propose a disruptive alternative to these traditional manufacturing methods by producing an on-site, on-demand paraffin wax emulsion for the manufacture of water-resistant gypsum wallboard.
