Weekly testing of the solvent using MAXICHECK™ Test Kits and adjustments with MAXISTAB™ Stabilisers if necessary. The bath exchange premium included in the COMPLEASE™ Chemical Leasing offer has not been utilized by Leonardo. Peter O’Shea explains: “The solvent remains in excellent condition, so there was no need to change the bath. But the security of knowing that the cost implication was addressed and prepared for in case anything untoward should happen is something that we would look to take forward now that the operation and running of the plant is fully in the hands of the operational department.” The chemistry option to be used was Aqueous cleaning systems were widely confirmed to be DOWPER™* MC in use across the Yeovil site having replaced Perchloroethylene which has widespread numerous open topped plants over several aerospace approvals.
