摘要： A coating composition can be applied with excellent high-speed coating properties and surface smoothness in a paint, an ink, and an adhesive which mainly contain polymers, or is a coating liquid for a positive electrode, a negative electrode, a separator, and the like of a lithium-ion secondary battery. The coating composition contains a filler, a binder, a thickener, and a solvent, wherein an aspect ratio of the filler is 2 or more, the binder is at least one selected from a diene rubber and a (meth)acrylate polymer, a viscosity of the coating composition is 1.0×106 Pa·s or less as measured at a shear rate of 0.01/s, and the following thixotropy index (TI) is 1.1×106 or more: [thixotropy index (TI)]=[viscosity of the coating composition as measured at a shear rate of 0.01/s]/[viscosity of the coating composition as measured at a shear rate of 10000/s].

摘要： Provided is a coating liquid composition that is less likely to deform even when heat is applied to a coating liquid for a paint mainly containing a polymer, an ink, an adhesive, and an anode, a cathode, or a separator of a lithium ion battery, for example. The coating liquid composition includes a filler, a solvent, a dispersant, and a thickener. When the coating liquid composition is applied to a substrate to form a coating film having a thickness of 0.5 to 20 μm, the coating film has a shrinkage rate of 20.0% or less when heating at 200° C. for 15 minutes.

摘要： Provided is a composition capable of forming an easy-drying coating on an application surface in a paint, an ink, and an adhesive which mainly contain polymers, or a coating liquid for a positive electrode, a negative electrode, a separator, and the like of a lithium-ion secondary battery. The coating composition containing a filler, a binder, a thickener, and a solvent, wherein the binder is at least one selected from a diene rubber and a (meth)acrylate polymer; a viscosity of the coating composition is 1.0×106 Pa·s or less as measured at a shear rate of 0.01/s; and the following thixotropy index (TI) is 1.1×106 or more: [thixotropy index (TI)]=[viscosity of the coating composition as measured at a shear rate of 0.01/s]/[viscosity of the coating composition as measured at a shear rate of 10000/s].

摘要： Provided is a composition that can form a coating film having excellent surface smoothness and high heat deformation resistance in a coating liquid for a paint mainly containing a polymer, an ink, an adhesive, and an anode, a cathode, or a separator of a lithium ion battery, for example. A coating liquid composition includes a filler, a solvent, a dispersant, and a thickener. When the coating liquid composition is applied to a substrate to form a coating film having a thickness of 0.5 to 20 μm, the coating film has a shrinkage rate of 15.0% or less after heating at 170° C. for 15 minutes.
