(hiips://www.dow.com/en -us/pdp.dowsil-7091-adhesive-sealant.02436621h.html), or with the
exactly the same specifications, with these recommended procedure:
Do this procedure in a clean and dry ambient, with humidity <60%
• Clean very well the contact surfaces
• Put the sealeant in the correct position

!!! ATTENTION !!!
The use of a sealant product with different specification (eg a simple silicon sealant), it could have
detrimental effects on sensors even in the short term. The expansions of materials due to
temperature variations, and the use of a non-compliant product can favor the penetration of
humidity inside the sensor box.
