Abstract
A method and apparatus for electrostatically spraying a plural component fast set polymer is disclosed. The system comprises a spray gun and at least two hoses connected to the head of the spray gun. The system also includes a proportioner connected to an end of the at least two hoses and a high voltage generator electrically and pneumatically in communication with the spray gun. The electrostatic spray system will allow for a fast set polymer to be imparted with electrical charge after mixing of a first and second component in a spray head thereof prior to expulsion via a nozzle to a grounded target that is being coated with the electrostatic spray coating.
