Additional Notes:
1. Performance was evaluated by determining the strength of samples before and after immersion in the
chemical solutions shown for 180 days at room temperature (22±3°C) according to the method described in
ASTM D-412.
2. Most of the results were obtained using saturated solutions of the chemical in water. Although it may
generally be assumed that a saturated solution represents the worst case, results may differ if more dilute
solutions are employed.
3. Most of the chemicals listed are solutions of inorganic compounds in water. With rare exceptions EcoProof is
not recommended for applications in which it is to be in contact with organic compounds such as oils or
solvents.
4. The list shown is not exhaustive. Please consult with your EcoProof Technical Representative for any
chemicals, or concentrations thereof which may be of interest but are not on the list.
5. EcoProof is not recommended for use with strong oxidizing agents.
6. All testing was carried using pure chemicals. In some cases the presence of even small quantities of
contaminants may dramatically affect the results.
7. Please contact your EcoProof Technical Department for information about chemicals not included on this list,
or if more than one chemical is present in the system.
8. “Limited” indicates that occasional contact with the chemical indicated may be tolerated but that continuous
exposure is unacceptable. In cases where limited acceptability is indicated, please consult with the EcoProof
Technical Department.
The information provided above was determined using EcoProof sprayed and cured using the recommended
procedures.
Samples of EcoProof were immersed in the solutions shown for 90 days at room temperature (20±2°C) before
examination.
The information is offered in good faith and is accurate to the best of our knowledge. Results may vary if the
EcoProof is incorrectly applied or if unknown contaminants are present.
The data provides no guarantee of performance and EcoProof accepts no responsibility for any problem which
might arise as a result of exposure of EcoProof to any of the chemicals described.
