Abstract
Official abstract text for this publication.
A paint composition contains (A) a binder component, (B) a first rheology control agent, and (C) a second rheology control agent, wherein the first rheology control agent (B) contains a reaction product of (b1) a polyisocyanate compound, (b2) a primary monoamine having a number average molecular weight of 300 or less, and (b3) a polyether amine having a number average molecular weight of more than 300 and less than 6000; the proportion of the polyether amine having a number average molecular weight of more than 300 and less than 6000 (b3) is 0.5 mass % or more and less than 10 mass % based on the total amount of the components (b1) to (b3); the second rheology control agent (C) contains a reaction product of (c1) a polyisocyanate compound, (c2) a primary monoamine having a number average molecular weight of 300 or less, and (c3) a polyether amine having two or more amino groups and having a number average molecular weight of 1000 or more and less than 6000; and the proportion of the polyether amine having two or more amino groups and having a number average molecular weight of 1000 or more and less than 6000 (c3) is within a range of 10 to 30 mass % based on the total amount of the components (c1) to (c3).
First claim
Opening claim text (preview).
The invention claimed is: 1. A paint composition comprising (A) a binder component, (B) a first rheology control agent, and (C) a second rheology control agent, wherein the first rheology control agent (B) contains a reaction product of (b1) a polyisocyanate compound, (b2) a primary monoamine having a number average molecular weight of 300 or less, and (b3) a polyether amine having a number average molecular weight of more than 300 and less than 6000, the proportion of the polyether amine having a number average molecular weight of more than 300 and less than 6000 (b3) is 0.5 mass % or more and less than 10 mass % based on the total amount of the components (b1) to (b3), the second rheology control agent (C) contains a reaction product of (c1) a polyisocyanate compound, (c2) a primary monoamine having a number average molecular weight of 300 or less, and (c3) a polyether amine having two or more amino groups and having a number average molecular weight of 1000 or more and less than 6000, and the proportion of the polyether amine having two or more amino groups and having a number average molecular weight of 1000 or more and less than 6000 (c3) is more than 15 mass % and 30 mass % or less based on the total amount of the components (c1) to (c3). 2. The paint composition according to claim 1 , wherein the polyether amine having two or more amino groups and having a number average molecular weight of 1000 or more and less than 6000 (c3) has three or more amino groups. 3. The paint composition according to claim 1 , wherein the binder component (A) contains a hydroxy-containing resin (A1) and a crosslinking agent (A2). 4. The paint composition according to claim 1 , wherein the content of the first rheology control agent (B) is within a range of 0.1 to 2 parts by mass, per 100 parts by mass of the solids content of the binder component (A), and the content of the second rheology control agent (C) is within a range of 0.1 to 2 parts by mass, per 100 parts by mass of the solids content of the binder component (A).
