Coal Tar vs. Asphalt Emulsion. What's the Difference .
Because coal tar is an extremely easy and forgiving product to use. Since coal tar does not have as high of a solid content as asphalt emulsion, coal tar does not clog tanks and spray systems nearly as much as asphalt emulsion does. The high solid content in asphalt emulsion causes the sealer to set-up fast if not cared for in these systems.
Asphalt Emulsion Additives
* DOSAGE: The quantity of the emulsifier depends, among other issues, type of asphalt, and dust quantity contained in aggregates. The emulsifier dosage is generally from 0.25 to 0.35 % w (from 2.5 to 3.5 Kg per ton of finished emulsion) * PRESENTATION: Iron drums of 200 Kg each one.

Asphalt - Wikipedia
Asphalt emulsion. A number of technologies allow asphalt to be mixed at much lower temperatures. These involve mixing with petroleum solvents to form "cutbacks" with reduced melting point or mixing with water to turn the asphalt into an emulsion. Asphalt emulsions contain up to 70% asphalt and typically less than 1.5% chemical additives.

agents. Asphalt emulsions used for road purposes have from 55 to 75% asphalt by weight dispersed in water. They also contain from 0.15 to 3.0% chemical emulsifiers usually added through the water phase. In many ways the chemical surface active agent appears to be the most important ingredient in an asphalt emulsion.
Dealing with and Coating Asphalt Emulsion Coated Roofs
Some asphalt emulsions are so heavily laden with emulsifiers and surfactants ("soapy stuff") that they can even reemulsify. This can be checked by applying a spot of water to the dried asphalt and rubbing with one's finger. If the water turns black and feels slippery, then the asphalt emulsion contains too much residual "soaps" to .
