Abstract

PURPOSE: To enhance dispersibility of a magnetic paint by performing admixing and dispersion of each component in two specified steps, in the preparation of the magnetic paint contg. a polyurethane resin and nitrocellulose as binders.
CONSTITUTION: In the preparation of a magnetic paint contg. said two polymers as finders, a magnetic powder and nitrocellulose are primarily dispersed, and then secondarily dispersed with addition of a polyurethane resin. A polyurethane resin of softening point ≤ about 150°C and average MW about 10,000W20,000 and "type RS" nitrocellulose manufactured by DAICELL Co. are used.
