Warning
The information in this chart has been supplied to Hayata by other reputable sources and is to be used ONLY as a guide in selecting equipment for appropriate chemical compatibility. Before permanent installation, test the equipment with the chemicals and under the specific conditions of your application.
Ratings of chemical behavior listed in this chart apply at a 48-hr exposure period.
Hayata has no knowledge of possible effects beyond this period. Hayata does not warrant (neither express nor implied) that the information in this chart is accurate or complete or that any material is suitable for any purpose.
Danger
Variations in chemical behavior during handling due to factors such as temperature, pressure, and concentrations can cause equipment to fail, even though it passed an initial test.
Serious Injury May Result
Use suitable guards and/or personal protections when handling chemicals.
