DUE TO n-Propyl bromide now being included in Annex 14 of REACH

EnviroTech Europe Ltd (ETE) continue to publish it as historical information and to record changes occurring in legislation which have affected decisions on formulations and equipment used in vapour degreasing - the most effective, quickest, flexible and cheapest cleaning system used in industry.

EnSolv® invented and patented by EnviroTech has been a market leader all over the world for vapour degreasing. It is based on n-bromopropane (nPB) which now cannot be used as a vapour degreaser within the UK or EU without authorisation.

Archived information about EnSolv®  can be found using the Discontinued Products & Resources navigation menu on this page.

Using experience accumulated over 40 years supplying and supporting users of the vapour degreasing process ETE specialists have developed “drop in” alternatives:
ProSolv®, ProSolv5408e®  and EnSolv CC-A® give the same or improved level of performance and economy as the original EnSolv® products.

EnSolv CC-A

The ONLY Boeing approved n-propyl bromide (npb) based vapour degreasing solvent for aerospace applications.

A safe and effective alternative is available to replace Trichloroethylene (TCE) and Perchloroethylene (PERC) for those required to meet the uncompromising standards of Boeing’s BAC 5408 vapour degreasing specification.

EnSolv®5408 was developed with a unique, patented stabilizer package, engineered to meet or exceed the stringent stability and cleaning requirements of BAC 5408.

EnSolv®5408 cleans as effectively or better than TCE and PERC, but is non chlorinated, non hazardous, non carcinogenic, environmentally friendlier and less likely to create stress corrosion or hydrogen embrittlement in titanium.

EnSolv®5408 has been approved as of June 15, 2006 by Boeing Aircraft Corporation under BAC5408 via PSD 6-59 as an alternative vapor degreasing solvent to TCE and PERC. As of February 5, 2008 PSD 6-59 has been superseded by PSDS 6-62 to permit the use of EnSolv Spec 490 Stabilizer Booster mixture.

EnSolv®5408 is the ONLY n-Propyl Bromide based solvent to succeed through the rigors of over four years of intensive testing by Boeing and is listed on the QPL of BMS 11-11.

EnSolv®5408 is the ONLY nPB based solvent approved for commercial and/or military applications.
