CHEMICAL COMPATIBILITY

A "Chemical compatibility guide"

catalogue can be downloaded from

our website:

www.francejoint.com

You can also use our online "

Chemical

compatibility" tool free of charge.

These two tools enable you to measure the behaviour of our materials that come into contact with the majority of

existing fluids. The data displayed is the result of rigorous testing at the ambient temperature and takes previous

publications into consideration. Test results are not fully representative because of the specific features of your

application. The tests performed actually do not consider additives and impurities that may exist under actual

conditions of use, nor the potential elevation of temperatures. Other parameters can also alter the behaviour of our

materials, such as the hardness, persistence, abrasion, etc. We therefore recommend performing your own tests to

verify the compatibility of our materials depending on your specific application. Our technical team can provide you

with any additional information.
