Preparation and characterization of antiglare waterborne polyurethane

A new method to fabricate an antiglare (AG) coating on glass substrates was demonstrated by controlling the content of 2-[(2-aminoethyl) amino] ethyl sulfonic acid sodium (A95) and hydrazine hydrate in waterborne polyurethane (WPU). The structure and morphology of the WPU coating were characterized by Fourier transform infrared spectrometer (FTIR) and scanning electron microscope (SEM). Antiglare properties of coated glass slides were measured by the 60 degrees glossiness and transparency. Results showed that the coated glasses possessed low gloss and high light transmission properties in the presence of nano-spheres. These characteristics signify its strong potential in various glass surfaces.
