Title:
WATER-BASE COATING COMPOSITION
Document Type and Number:
Japanese Patent JPH0753907
Kind Code:
A
Abstract:

PURPOSE: To shorten the drying time of a coating compsn. comprising a synthetic resin dissolved or dispersed in a water-sol. solvent by mixing the compsn. with a specific carboxyalkylcellulose nitrate.

CONSTITUTION: A coating compsn. comprising a synthetic resin dissolved or dispersed in water or a water-sol. solvent mainly comprising water (e.g. a water- base acrylic resin coating compsn.) is compounded with 0.1-80.0 wt.% (based on the solid content of the compsn.) carboxyalkylcellulose nitrate having a degree of nitration per anhydrous glucose unit of 0.2 or higher and a degree of carboxyalkyl-etherification per anhydrous glucose unit of 0.05 or greater. The compsn. is further compounded with a cross-linker, a pigment, a filler, a flow improver, a defoamer, a flame retardant, an antioxidant, etc. First the carboxyalkylcellulose nitrate is mixed with water and a small amt. of an org. solvent to prepare an aqua soln. or dispersion, which is added to the coating compsn. Then, the compsn. is mixed with other additives and adjusted to specified solid content and viscosity.
