Definitions

  • the technical field of the invention is that of methods for applying or dispersing an active material.
  • Active material will be understood to mean a material fulfilling a certain function when it is applied to a target or else dispersed over an area of ground.
  • the active materials are used either in the form of a powder or in the form of a liquid.
  • the liquids are generally dispersed by means of a pressurized gas, which requires the implementation of security and seals for storage.
  • compositions in liquid form also poses sealing problems.
  • the active material is a powder mixed with a carrier liquid
