Application of Polymeric Microspheres from Non-aqueous Dispersion to Coatings Area

摘要

The NAD coatings composed of a mixture of NAD/solution acrylic polyol/melamine formaldehyde resin(MFR) give a typical two-phase structured system not only in liquid enamel but also in crosslinked films with discrete polymer particles, which brings out specific fcatures in the coatings performance. The functions of NAD in high solids coatings are demonstrated: as a rheology control agent of the liquid, as a fortifier and as a stress relaxation agent of the film.
