polyurethane and
fluorine-contained
acrylic resin are grafted innovatively, and the synthesized environmentally-friendly resin has the excellentee
emulsion. The unsaturated double-linked water-based polyurethane and fluorine-contained acrylic resin are grafted innovatively, and the synthesized environmentally-friendly resin has the excellentperformance of both
