Mineral Oil Base Black, or "MOBB" for short, is a dispersion of 25% carbon black in a severely hydrotreated, low-odor, zero-VOC mineral oil. MOBB is intended primarily as a commodity item for the manufacture of newsink, but finds many other uses as well.
Among them, MOBB serves as an excellent starting point for typewriter ribbon inks, computer printer ribbon inks, and special never-dry marking and fingerprinting inks. MOBB is excellent for any application where intense black color is needed in a base which will never dry out. When approximately 30% hydrocarbon varnish is added to 70% MOBB, a web offset newsink is obtained. When the base is cut with petroleum oil and resinated slightly with varnish or pitch, a letterpress newsink is obtained. The carbon black pigment in MOBB is thoroughly milled down to micron particle size, so no further processing beyond thorough mixing with diluting agents is necessary, as the base has been more than adequately milled by us.
MOBB is compatible with petroleum-based oils and solvents and also with vegetable oils such as soybean oil and linseed oil. MOBB cannot be used with lower alcohols, ketones or esters.
