1.1 These practices describe laboratory procedures for preparing an oil-based ink resin solution in a high-boiling solvent using four pieces of lab equipment; (1) a hot oil bath (Sections 4 to 11),
(2)a stirrer/hot plate (Sections 12 to 16),
(3)an industrial blender (Sections 17 to 22), and
(4)a hot air gun (Sections 23 to 27 ). ASTM Subcommittee D01.37 recommends using the hot oil bath procedure (Practice D 5597) where possible.
1.2 These practices use laboratory equipment generally available in a normal, well-equipped laboratory.
1.3 One or several of these practices allows for rapid resin solution preparation (under 30 min, typical), can regulate the maximum temperature, can be done under an inert atmosphere, and can prevent the random solvent loss during preparation.
1.4 These procedures are for use with ink resins intended mainly for oil-based offset and letterpress inks. The type of resins are typically, but not limited to C
1.5 The typical high boiling solvents to be used include C
1.6 To avoid fire or injury, or both, to the operator, these practices should not be used with low flash point solvents such as toluene or xylene. The minimum flash point of the solvents used should be 60°C (140°F) as determined by Test Method D 56. (
1.7 The values stated in SI units are to be regarded as the standard. The values given in parentheses are for information only.
1.8 This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety and health practices and determine the applicability of regulatory limitations prior to use.
