Hydrophilic anti-fog coatings

The present invention relates to hydrophilic anti-fog coatings. In particular, the coatings use two types of nanoscale particles, colloidal silica and porous organosilicate micelles, in a polyurethane matrix. The invention is an anti-fog coating for optically clear substrates (polycarbonate, polyurethane, nylon, polyester and other clear plastics) without the need for a primer and glass substrates with an additional primer layer, comprising monosized colloidal silica nanoparticles and porous organosilicate micelles in a polyurethane matrix. The silica is preferably 1-5% by weight and the micelles are loaded at 0.1 to 10% volume percentage by volume. The polyurethane prepolymer is dissolved at 10-40% by weight in a mixture of tertiary amyl alcohol and diacetone alcohol to customize for dip, flow or spray coating processes.

Urethane Acrylic Hybrid Polymer Dispersion with Robust Dry/Wet Adhesion and Basecoats Prepared Therefrom

This invention relates to urethane acrylic hybrid polymer dispersion with robust dry/wet adhesion and the basecoats prepared therefrom for automotive applications. In this system, the polyurethane dispersion (PUD) prepolymer is based on a combination of polyols and aliphatic diisocyanates. The acrylic portion is based on (meth)acrylated monomers. A combination of this hybrid polymer dispersion and other resins having defined glass transition temperature (T.sub.g) values, organic and/or inorganic rheology modifiers, and different additives including pigment, dispersant, and defoamer are used to prepare waterborne basecoats having modified appearance and performance. The final coatings show excellent dry/wet adhesion to the primer for automotive applications.

Method for producing a multicoat paint system on plastics substrates

The present invention relates to a method for producing a multicoat paint system on a plastics substrate, in which a basecoat film or a plurality of directly successive basecoat films are produced on a plastics substrate, a clearcoat film is produced directly on the one basecoat film or on the topmost of the plurality of basecoat films, and subsequently the one or more basecoat films and the clearcoat film are jointly cured, this method being a method wherein at least one basecoat material used for the production of the basecoat films comprises at least one aqueous polyurethane-polyurea dispersion (PD) comprising polyurethane-polyurea particles, where the polyurethane-polyurea particles present in the dispersion (PD) comprise anionic groups and/or groups which can be converted into anionic groups, and have an average particle size of 40 to 2000 nm and also a gel fraction of at least 50%.
