Master Bond has released EP42HT-2FG, a new foodgrade epoxy system that has been independently tested and certified by a national laboratory to meet requirements of the Food and Drug Administration’s CFR 175.300. It also was toxicologically evaluated to meet the NSF/ANSI 51.4.1 (2009) standard for food equipment materials.

Foodgrade-certified epoxy EP42HT-2FG may be used across a variety of applications in the food industry, such as bonding and sealing metals, plastics, rubbers and other substrates commonly found on foodservice equipment. Featuring high resistance to chemicals and many solvents, along with boiling water, fats, and oils, it may be readily used as a coating for storage tanks, bins, hoppers, and other containment vessels.

Capable of withstanding extreme conditions over the service temperature range of –60° to +450° F (FDA certification done at temperatures specified in the test protocol), EP42HT-2FG resists steam, radiation, and frozen storage conditions.

With a volume resistivity of more than 1014 ohm-cm, EP42HT-2FG also serves as a potting and encapsulation compound for electronic components and devices. It has a low viscosity of 55,000-110,000 cps for Part A and 75-130 cps for Part B at room temperature. This adhesive has a tensile strength greater than 12,000 psi and a tensile lap shear strength exceeding 2,000 psi at 75° F.

This two-part epoxy offers easy handling with an open time of 45-75 minutes for a 100-gram mass at 75° F. EP42HT-2FG has convenient color coding (Part A is clear, Part B is amber) for its 100:30 mix ratio by weight. The recommended cure is three to four hours at 150-200° F. Alternatively, it can be cured at room temperature overnight followed by a two- to three-hour cure at 150-200° F.

EP42HT-2FG comes in half-pint, pint, quart, gallon, and five-gallon containers. Its shelf life is one year when stored at room temperature in its original unopened container.
