HELOXY 71 | Hexion Modifier
Aliphatic Epoxy Ester Resin, Increased Flexibility, Low Viscosity & Thermal Shock Resistance
HELOXY 71 is an undiluted amber colored, low-viscosity liquid, aliphatic epoxy ester resin that imparts increased flexibility and resistance to thermal shock when blended with conventional liquid bisphenol A based epoxy resins.
HELOXY 71 Application Areas/Suggested Uses
- Body solders
- Adhesives
- Caulking and sealing compounds
- Electrical casting and encapsulating
- Glass to metal glazing compositions
- Large castings
- Tooling compositions
- Filament winding
HELOXY 71 Benefits
- A low-viscosity flexibilizer that serves as a viscosity depressing agent.
- A product that improves impact strength and toughness to a conventional liquid bisphenol A epoxy resin.
FDA Status
HELOXY 71 is not listed under the Code of Federal Regulations (21 CFR); therefore, Hexion cannot recommend its use for food contact applications.

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.
