Abstract
The invention relates to a method for coating a substrate with a fluid. This method comprises the steps: (i) of supply of a substrate and of a yield point fluid; and (ii) of shearing of the fluid and of application of the fluid to the substrate, the fluid supplied comprising a solvent-free reactive polyurethane mixture.
