Scope

1.1 This practice covers a laboratory procedure for preparing an oil-based ink resin solution in a high boiling solvent using a hot oil bath.

1.2 This practice uses laboratory equipment generally available in a normal, well equipped laboratory.

1.3 This practice allows rapid resin solution preparation (typically 30 to 45 min) and regulates the maximum temperature under an inert atmosphere, preventing the random solvent loss during preparation.

1.4 The procedure is for use with ink resins intended mainly for oil-based offset and letterpress inks. The types of resins are typically, but not limited to, C 9 aromatic hydrocarbon resins, modified dicyclopentadiene resins, rosin pentaerythritol or glycerin esters, phenolic-modified rosin esters, maleic anhydride-modified rosin esters, and naturally occurring resins such as gilsonite.

1.5 The typical high boiling solvents to be used include C 12 -C 16 petroleum distillates, texanol isobutyrate, alkali-refined linseed oil, tridecyl alcohol, or combinations of the above.

1.6 To avoid fire or injury to the operator, or both, this procedure 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.

1.7 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.
