ProSolv ® 5408e a sustainable , economical cleaning solvent for vapour degreasing in the aerospace industries
The aircraft and aerospace component manufacturing industries face many critical cleaning applications during manufacturing processes and for finishing where surfaces need to be completely degreased leaving no residues . Although aqueous cleaning would seem to be the method of choice for environmental reasons with new advancements in cleaning solvent chemistry this is often not the case . Vapour degreasing is the most effective process , economical in use with lower energy uses , one tank needing less floor space than multi tank water-based systems and safe for users .
ProSolv ® 5408e has been developed to be used in place of the traditional chlorinated hydrocarbon solvents , trichloroethylene and perchloroethylene and those based on n-propyl bromide ( nPb ) which have been phased out for use as vapour degreasing solvents in the EU . The ProSolv ® 5408e advanced formulation , based on sustainable solvents , has been extensively tested with oils , soils greases and other contaminants from the manufacturing process and with is high KB value all these materials are easily removed to comply with aircraft standards for cleaning and degreasing to the highest levels . No titanium surface cracking or deleterious effects on other metals or composites commonly used for aircraft and aerospace component manufacture have been identified .
The innovative ProSolv ® 5408e formulation produced by Envirotech Europe ticks all the boxes with the perfect profile for vapour degreasing Soft on the environment with near zero ozone depletion potential ( ODP ) and very low global warming potential ( GWP ) its lower boiling point at 48C minimises energy requirements giving reduced process times for greater throughput and comfortably handled critically cleaned parts . The incredibly low surface tension guarantees penetration into micron sized through and blind holes and between close contact surfaces .
Stable in use ProSolv ® 5408e is safe for users with a high 8hr occupational exposure level of 220ppm . The solvent needs no additives or stabilisers and requires no testing . Sustainable , safe and secure for future use as your forever solvent .
