Waterborne PU Coating as DMF-Free Alternative
topic
Water-based polyurethane dispersion coating applies aqueous PU at 30 to 50 percent solid content by knife or gravure coating followed by drying at 100 to 140 degrees Celsius that coalesces the PU dispersion particles into a continuous film, producing coatings that approach the performance of DMF-based systems for most applications while eliminating DMF handling, recovery, and residue compliance requirements through solvent-free formulation.
Role
Provides the increasingly preferred environmentally compliant alternative to DMF-based solvent coagulation by producing PU coatings through aqueous dispersion technology that eliminates the reproductive toxin DMF from the production process, with waterborne PU adoption being driven by regulatory tightening of DMF exposure limits and customer sustainability requirements that increasingly specify DMF-free production for consumer-facing textile products.
