what will you be applying your topical solution to, is it a medical application, an industrial application, an ink application, etc. Furthermore, will it be applied to the skin, paper, a rough surface, etc.?
*Each customer should have an idea of what type of flow they want the applicator to generate. We sell control flow applicators and in order to control the flow of a solution, we use various types of springs and coverings. It is a good idea to let us know what the viscosity of the solution is as well as what type of flow you are looking for our applicator to dispense. Is it a glue, an alcohol base, an ink type, etc.
