*Chemical may cause tank material to discolor.
** 316SS may pit upon drying. Not recommended for SUMOs.
*** There are a wide variety of polymer chemical compositions. To confirm compatibility, secure a Safety Data Sheet (SDS) and have it reviewed by Snyder. Feel free to email us at info@tankgurus.com and we'll coordinate with Snyder. High purity chemical applications are limited to natural tank color or special hot compounded resins.

For chemicals or chemical blends not listed on the above chart, please contact us at info@tankgurus.com and we'll help you out.
