An approximate shelf-life of TERATHANE® PTMEG is two years if the product is stored in the original container at ambient temperature under a dry nitrogen blanket and tightly closed. Because storage and local ambient conditions vary and INVISTA has no control over the practices, procedures and conditions at a customer’s facility, the shelf-life estimate provided should be used as guidance only. It is not provided as a guarantee of any shelf life.

TERATHANE® PTMEG contains an oxidation inhibitor (BHT) per the following:
