Beschreibung
Zusammenfassung:	The present invention relates to a filler composition comprising A) at least one hydroxy group-containing polyacrylate comprising 40-70 wt. % aromatic vinyl monomers and/or methyl methacrylate, 25-40 wt. % hydroxy-functional (meth)acrylic monomers, 0-20 wt. % (meth)acrylic monomers having at least 2 carbon atoms in the alkyl group, and 0.5-2.5 wt. % (meth)acrylic acid, wherein the hydroxy group-containing polyacrylate has a hydroxy value of between 100 and 160 mg KOH/g solid resin, an acid value between 5 and 20 mg KOH/g solid resin, a Mw higher than 15,000 and a Tg between 25 and 100° C., B) at least one polyisocyanate compound, and C) at least one pigment, the filler composition having a pigment volume concentration ranging from 40 to 80 % on solids. The filler composition of the present invention may be used for sanding and non-sanding applications, cured with a large variety of polyisocyanates, and covered with conventional top coats. The filler may be used within a broad temperature and humidity range. Its properties are equal to those of commercial fillers or an improvement thereon.
