Safety, Storage & Handling
Please refer to the MSDS for the most current Safety and Handling information. Please refer to the Hexion web site for Shelf Life and recommended Storage information. CAUTION: Hexion has found that HELOXY 71 will have a viscosity/epoxide equivalent weight increase of about 10% per month when stored at 30 °C (86 °F). As this occurs, the compatibility with other epoxy resins, such as EPON Resin 828, will decrease. We recommend the product be stored at 13 °C (55 ° F), or lower, in order to maintain a reasonable shelf life. Also, the oldest production of HELOXY 71 should be consumed first.
Sizes Available
Available in quart, gallon, 5 gallon, and 55 gallon drum sizes.
