MAXISTAB Stabilizers OverviewRecent advances in operating techniques, equipment upgrades, and new fully enclosed systems have significantly reduced solvent losses from vapor degreasers. While solvent conservation is clearly a benefit, it does require more careful management of stabilizers. Here's why: During the degreasing process, both solvents and oils can decompose and produce acids. These acids not only can corrode the parts being cleaned, but also the cleaning equipment itself. Although chlorinated solvents are formulated with stabilizers to inactivate these acids, stabilizers are continually depleted during the normal degreasing operations. Stabilizer depletion is further accelerated with the use of exhaust air systems that employ activated charcoal. In the past, frequent addition of new solvent to the vapor degreaser would replenish the depleted stabilizer. But now, very little solvent is added. In addition, repeated distillation and recycling put even greater stress on the solvent, increasing the possibility of stabilizer loss and solvent degradation. MAXISTABChlorinated solvents contain application specific stabilizers to avoid acidification. During extended use of the solvent, stabilizer can deplete and restabilization might be needed. Depending on solvent grade and application, different MAXISTAB™ restabilizer concentrates are available from your solvent distributor to maintain proper stabilizer level.
