Aminoharz-Dispersionen, deren Verwendung und Verfahren zu ihrer Herstellung

DE 10226789 A UPAB: 20040218 NOVELTY - An amino resin dispersion including a disperse phase and a continuous phase containing hydrophilic and hydrophobic components where the disperse phase contains a hydrophobic component based on amino resin and the continuous phase a hydrophilic amino resin or a precondensate of this dissolved in a polar solvent, or the continuous phase contains a hydrophobic phase based on amino resin and the disperse phase contains a hydrophilic amino resin or a precondensate of this dissolved in a polar solvent is new. DETAILED DESCRIPTION - An amino resin dispersion including a disperse phase and a continuous phase, where either (a) the disperse phase contains or consists of a hydrophobic component based on amino resin and the continuous phase comprises a hydrophilic amino resin or a precondensate of this dissolved in a polar solvent, or (b) the continuous phase contains or is a hydrophobic phase based on amino resin and the disperse phase is or contains a hydrophilic amino resin or a precondensate of this dissolved in a polar solvent is new. INDEPENDENT CLAIMS are included for: (1) a method for preparation of the dispersion by introduction of the hydrophilic amino resin dissolved in a polar solvent or a precondensate of this optionally in the presence of one or more additives, and dispersion in the mixture of the amino resin based hydrophobic component; (2) a cured aminoplast obtainable by curing the amino resin dispersion. USE - The amino resin dispersion is useful in the preparation of decorative surfaces, boards, or commercial laminates (claimed). ADVANTAGE - The polymer dispersion has a decreased volatiles and increased polymer content.
