Chemical Resistance Guide for Flowchem EPN
This guide is designed to aid in the proper selection of material for every job application. Exposure to over
250 chemicals are rated for specific temperature ranges. Due to the number of variables involved in each
application, it is recommended that the Technical Department be contacted for specific recommendations.
This Chemical Resistance Guide is intended only as a guideline and does not constitute an implied warranty
for the use of our materials under the environments indicated.
Instructions for use
The chemical resistance data contained in this guide has been summarized from in-depth laboratory analysis
and actual job performance. The rating system shown below is designed to consider most application
variables. Choose the closest chart temperature, 38˚C or 66˚C. The rating gives the maximum service for a
chemical at that temperature.
Please Note:

Discoloration is not classified as chemical attack if hardness is unchanged.

Higher temperatures will reduce the chemical resistance shown in the performance table.

Some chemicals may concentrate due to evaporation and become more aggressive.

Mixtures of chemicals can be more aggressive than might be expected from the individual components alone.

Solvent resistant performances, in practice, are expected to exceed the values noted in the performance table due to
good housekeeping combined with evaporation.

The chemical resistance of Epoxy screed systems will be influenced by the integrity of the surface sealer – this being
dependent upon service conditions and housekeeping.
The assessment is based on a resin rich screed where permeation by liquid chemicals is minimal.
The use of a highly filled screed will significantly reduce the chemical resistance shown in the performance table.

Chemical resistance key
I = Resistant to Immersion
S = Resistant to Splashes or Spills
NR = Not Recommended
Notes:
• For immersion conditions over 66˚C, contact Technical Department.
• For solutions with no concentrations given, the rating is for all possible concentrations.
* Indicates chemicals where carbon filled systems are required. Consult Technical Department.
