Beschreibung
Zusammenfassung:	Propellant free amino resin foam (I) comprises amino resin and at least a hydrophobic nanoparticle of an inorganic and/or organic material at the surface. An independent claim is included for a prepartion of propellant-free amino resin foam comprising dispersing a mixture of an aqueous solution containing at least an amino resin foam-prepolymer and at least a surface hydrophobic nanoparticle of an inorganic and/or organic material; condensating the amino resin prepolymer by simultaneous intensive interfering of air to produce a ternary dispersion of amino resin/nanoparticles/air; and thermally inducing the dispersion to the amino resin foam.
