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.

An electrostatic spray system for spraying plural component fast set polymers, said system comprising:
- a spray gun;
- at least two hoses connected to a head of said spray gun;
- a proportioner connected to an end of said at least two hoses;
- and
- a high voltage generator electrically and pneumatically in communication with said spray gun.
A method of electrostatically spraying a fast set polymer material, said method comprising the steps of:
- connecting a spray gun to a high voltage generator and a proportioner;
- grounding a target which is being sprayed;
- triggering said spray gun to begin a predetermined spray pattern;
- activating said high voltage generator to send a predetermined voltage to a spray head of said spray gun;
- charging the material as it passes through said spray head;
- and
- releasing a trigger of said spray gun to stop said spray pattern and said voltage from being sent to said spray head.
