低放出塗装組成物用結合剤
Document Type and Number:
Japanese Patent JP3986617
Kind Code:
B2
Abstract:
Binders comprising at least one aqueous polymer dispersion with a minimum film-forming temperature less than 10 degrees C are prepared by radical aqueous emulsion polymerisation of monomer mixtures that contain the following components :(A) 45-70 parts by weight at least one monomer whose homopolymer has a glass transition temperature (Tg) less than 20 degrees C ; (B) 30-55 parts by weight at least one monomer whose homopolymer has a Tg greater than 50 degrees C ; (C) 0-1 part by weight at least one monomer with acidic groups ; and (D) 0-2 parts by weight at least one extra monomer chosen from amides, alpha , beta -unsaturated 3-6C carboxylic acids (or their hydroxy-(2-6C alkyl)-esters) and/or N-vinyl lactams. Low emission, solvent-free coating materials containing at least one of these binders are also claimed.
