EnSolv Spec 490 Additive
Keep Your EnSolv 5408 Cleaning at Optimum Levels
Approved by Boeing to Re-Condition your EnSolv 5408
With Enviro Tech EnSolv Spec 490 Stabilizer Additive, you can keep your EnSolv 5408 bath well within Boeing's spec and lasting longer than ever. Although it's not required due to the superior lifespan and stability of the patented EnSolv 5408 cleaning solution, Boeing has approved the addition of Spec 490 to maintain your solvent within specification per PSD 6-62.
A 5 gallon pail of Spec 490 contains enough of the patented EnSolv 5408 stabilizer package to bring at least 55 gallons of EnSolv 5408 back to like new levels of stability and conditioning. But the bottom line is, you probably will never need to add it because EnSolv 5408 is THAT stable. We do recommend keeping one 5-gallon pail on hand in case of emergencies though.
Technical Details
General Instructions
Before adding Spec 490 Stabilizer Additive to EnSolv 5408, the acid acceptance level of the solvent should be determined using an Acid Acceptance Test Kit, available from Enviro Tech. If the solvent’s acid acceptance level is low (e.g., 0.19 weight percent sodium hydroxide or less), either fresh EnSolv 5408 or Spec 490 can be added to restore it to an acid acceptance level that is equal to or greater than 0.25 weight percent sodium hydroxide (See the Acid Acceptance test instructions link on the left for more information). Follow the recommendations on the B oeing PSD 6-62 specification in all cases. If acid acceptance falls to 0.10 weight percent NaOH or less, discard the EnSolv 5408 bath and replace with fresh solvent. Contact Enviro Tech International for assistance in disposing of spent EnSolv 5408, in many cases FREE OF CHARGE. EnSolv 5408 should never be allowed to turn acidic. The acidic condition could become evident by a reddish brown solvent color, an acrid solvent odor, or a low pH of, for example 3.0 or less.
