| 摘要 |
<p>The invention relates to the use, in an aqueous-phase alkyd resin formulation, of a dispersant/thickener pairing: the dispersant is a copolymer of (meth)acrylic acid with an alkoxylated monomer possessing a polymerizable function and terminated by hydrogen or an alkyl group having 1 to 4 carbon atoms, and the thickener is an associative thickener containing at least one hydrophobic group which is a polystyrylphenyl, preferably selected from distyrylphenyl, tristyrylphenyl and mixtures thereof, and which very preferably is tristyrylphenyl. This combination makes it possible to enhance the gloss retention of the paint film over time, while providing the aqueous formulation with the desired rheology.</p> |
