ChemMAX

ChemMAX coveralls have been tested against a wide range of commonly used chemicals to indicate the fabric ability to resist permeation according to EN 369. In some cases, according to the requirements of the latest version of EN14065 - 2005 seams have also been tested to show any permeation that may occur at the seam.

Note that these figures indicate laboratory test results only and are intended to provide an indication only and do not guarantee any duration of safe use in any application or against any specific chemical. Further chemical tests can be requested - please contact us at
