Abstract (en)
[origin: WO2020216850A1] The invention relates to an aqueous polymer dispersion, with said polymer comprising in its structure incorporated monomer units, from a monomer composition comprising: a) at least one (meth)acrylic monomer which is a C1-C18 (meth)acrylic ester, with no ionic group; b) at least one ethylenically unsaturated monomer having at least one carboxylic acid group; c) at least one ethylenically unsaturated monomer having a tertiary amine, and with said polymer additionally having blocked silane grafted groups in the form of -Si(OR1)3 or -Si-R2(OR1)2 or -Si-(R2)2(OR1), preferably -Si(OR1)3 or -Si-R2(OR1)2 with R1, R2 being the same or different C1 to C4 alkyl, and with said blocked silane graft groups being incorporated by at least one of the following two paths or the combination thereof; d) presence with the monomers a), b) and c) of at least one ethylenically unsaturated comonomer d) having, in addition to said ethylenic unsaturation, at least one blocked silane group as defined above and/or e) presence with the monomers a), b) and c) of, or after-treatment of the aqueous dispersion by, at least one silane compound e) having at least one blocked silane group as defined above and at least one functional group selected from: epoxy, amino, thio, hydroxy, isocyanate, preferably epoxy, the latter group being capable of reacting, at least in part, with the carboxylic groups of said monomer b). The invention also relates to a coating composition comprising said dispersion of the invention and the use thereof for aqueous protective coating compositions for wood.
