Lawter - Model Optilith 3094 -Anti-Oxidant Additive

Optilith 3094 may also be used beneficially in regular heatset inks that will be kept in Tote Bins. Although regular heatset inks are not readily prone to skinning, it can occur especially with Phthalo Blues. The potential problems and costs associated with contaminating a printer`s pumping lines to multiple presses and with cleaning out Tote Bins, if skinning occurs, can make it worthwhile to incorporate from 0.5% to 1.0% of Optilith 3094.

Optilith 3094 may be used in sheetfed inks but should be held to a level around 0.5% or less. Levels above 0.5% in sheetfed inks can cause problems with slow through-drying when printing heavy coverage (over 250%) of process colors. Optilith 3094; at this level, will not prevent skinning indefinitely in sheetfed inks containing driers. But, it will function as a retardant to reduce the tendency to dry up on the press rollers when the press is sitting idle for several hours.

Optilith 3094 contains 1,4 Benzenediol, CAS No. 123-31-9, which is subject to the reporting requirements of Section 313 Sara Title III.
