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 by use of a polyurethane resin and nitrocellulose as binders.
CONSTITUTION: In the preparation of a magnetic paint consisting of a magnetic powder, binder, lubricant, abrasive material and additive by use of said two polymers as said binder, the magnetic powder and nitrocellulose are primarily dispersed and then secondarily dispersed with addition of the lubricant and a polyurethane resin. A 14W20C saturated fatty acid (e.g., myristic acid) in an amt. of about 0.01W10pts.wt./100pts.wt. said magnetic powder, is used as lubricant.
