Abstract
A rheology control agent for water-based resins may include: 1 mass % or more and 30 mass % or less of an active matter (X) containing a diamide compound (A) and/or a hydrogenated castor oil (A′), the diamide compound (A) being obtained by reacting a diamine component (A1) selected from the group consisting of diamines having 2 to 12 carbon atoms with a monocarboxylic acid component (A2) selected from the group consisting of monocarboxylic acids having at least a hydroxyl group; and 5 mass % or more and 99 mass % or less of a first solvent (C) having at least one substituent selected from the group consisting of a hydroxyl group, an ether group, an ester group, an amide group and a ketone group.
Claims11
A rheology control agent for water-based resins, the rheology control agent comprising:
- 1 mass % or more and 30 mass % or less of an active matter (X) based on a total mass of the rheology control agent, the active matter (X) containing a diamide compound (A) and/or a hydrogenated castor oil (A′), the diamide compound (A) being obtained by reacting a linear or branched diamine component (A1) selected from the group consisting of diamines having 2 to 12 carbon atoms with a monocarboxylic acid component (A2) selected from the group consisting of monocarboxylic acids having at least a hydroxyl group;
- and
- 10 mass % or more and 99 mass % or less of a first solvent (C) based on the total mass of the rheology control agent, the first solvent (C) having at least one substituent selected from the group consisting of a hydroxyl group, an ether group, an ester group, an amide group and a ketone group, wherein
- a total content of the diamide compound (A) and the hydrogenated castor oil (A′) is 60 parts by mass or more when a total amount of the active matter (X) is 100 parts by mass,
- the first solvent (C) is at least one solvent selected from the group consisting of glycol-based solvents, diglycol-based solvents, triglycol-based solvents, ester-based solvents and amide-based solvents,
- the ester-based solvents are at least one selected from the group consisting of dibasic esters, propylene glycol monomethyl acetate, amyl propionate, ethyl ethoxypropionate, and 2,2,4-trimethyl pentanediol monoisobutyrate, and
- optionally, the active matter (X) further contains a polyamide compound (B) obtainable by reacting a diamine component (B1) with an excess of a dicarboxylic acid component (B2) relative to the diamine component (B1), the polyamide compound (B) has an acid value of 30 or more and 140 or less, and a content of the polyamide compound (B) is 40 parts by mass or less when a total amount of the active matter (X) is 100 parts by mass.
