Significance and Use | ||||||||||||||
5.1 These practices provide means of preparing small quantities of resin solution (in some procedures in an inert gas atmosphere using uniform, controlled heating). 5.2 This practice provides quick ways to prepare a resin solution for quality control testing during the manufacture of resin solutions and vehicles. Samples can usually be prepared in approximately 30 to 45 minutes or less. 5.3 These practices can be used to prepare commonly specified ink test solutions such as 33.3 % resin in alkali refined linseed oil, and 50 % resin in heat-set ink solvent (that is, C12 to C16 hydrocarbon petroleum distillate with initial boiling point (IBP) about 470°F). |

1. Scope | ||||||||||||||
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; ((2) a stirrer/hot plate (Sections 12 to 16), (3) an industrial blender (Sections 17 to 22), and (4) a hot air gun (Sections 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 C1.5 The typical high boiling solvents to be used include C12 to C16 petroleum distillates, 2,2,4 trimethyl 1,3-pentanediol di-isobutyrate,2 alkali refined linseed oil, tridecyl alcohol, or combinations of the above. 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 D56. (Warning—Users of this practice should be aware that the flash point of many solvents used for this test (as defined in Test Methods D56 and D1310) is exceeded in the heating cycle of this test method. Take safety precautions since there is the potential for vapor ignition. Do the methods outlined in a shielded exhaust hood, where there is access to a fire extinguisher if needed.) 1.7 The values stated in SI units are to be regarded as 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.
