Paint Formulation
Sodium Tetraborate (anhyd.)/156
Color WDB 4675/200
Water/94.7
"Carbopol" 934/200
Masterbatch/5.3
Brookfield Visc., 20 rpm/28,600 mPa.s or cP

配制方法:

Ball mill the masterbatch until desired pigment fineness. Carefully disperse the ball-milled masterbatch in the water in the proportion noted.
Note: The paint has excellent stability, and after it has dried it can be rewet and reworked. If the masterbatch is to be stored more than a few days, anhydrous sodium tetraborate must be used. Hydrated borax will cause the masterbatch to ball up into a tough, rubbery mass. Also pigments containing antimony oxide will react with "Carbopol" resins pigments containing antimony oxide will react with "Carbopol" resins and form an unusable, rubbery mass. Use pigments that are relatively inert.
