68 Marking Ink Black, 1 Quart

Specifications:  Meets or exceeds Specification RBO125-011 / ABO290-002 Type 1 Class 1

Recommended Substrates:  Most non-porous surfaces such as metals, plastics, packaging film and some rubber products. When marked on a clean, dry surface it is waterproof and resistant to some oils.

Adherence: Even though it is a non-etching ink the adherence qualities are good on cleanbare metals of all kinds, glass, most plastics, and rubber compounds with the exception o fsilicone. Prior to testing adherence, we recommend an air-dry period of 24 hours. An application of heat (when the surface temperature reaches 250°F) for 30-45 minutes will give even better adherence and greater solvent resistance.

Resistance:  It is resistant to water, salt spray,gasoline, lubrication oils, alipathics, hydrocarbons, many alkaline and detergent compounds,as well as some degreasing solvents. Exposure to temperatures up to 350°F does not appreciably affect adherence although the shade of some colors may change slightly.

Corrosion: Since the ink is not compounded with toxic or harmful acids, it is noncorrosive on aluminum alloys, magnesium, stainless, titanium, and many of the exotic space-metals.
