| In the surface coating industry waxes are widely used to modify surfaces by providing water repellency, scratch and mar resistance. These waxes are provided in different forms such as wax emulsion, wax dispersion & micronized powders. Wax emulsion is a stable homogenous dispersion of wax (mix of paraffin & polyethylene wax and various additives) and water with no solvent. The particle size of a wax emulsion is normally less then on one micron. The main functions of wax emulsion in the water borne exterior coating are by adding or modifying the following properties. |
To improve weather ability & slip.
Water resistance.
Rub resistance.
Lubricity.
Eggshell finish.
Anti fungal.
Corrosion resistance.

| Order of Addition |
| The order of addition of various materials is very important. Agglomeration
can be prevented and over all stability is maximized if preferably Wax Emulsion is added at last
under controlled pH. |
