  • Method for coating carriers, emulsion used therein, resulting coated materials, and devices for producing and laying coated materials
    Patent number: 5919573
    Abstract: A process for the bituminous coating of any supports by providing a cold coating of the supports by bituminous emulsions, comprising first obtaining a hydrophobic powder of positive electric charge by the conjoint action of a metallic salt soluble in water and a long chain organic acid, then introducing this powder, either into a mass of the supports to be coated, or into a bituminous anionic emulsion and then mixing the supports and bituminous emulsion in a mixer so as to effect cold coating. An anionic emulsion is mixed with a hydrophobic powder of positive electric charge so as to confer on the emulsion a cationic behavior and coating and covering properties.
