Master Bond is pleased to announce the release of EP42HT-2FG, a new food grade epoxy system. EP42HT-2FG has been independently tested and certified by a leading national laboratory to meet the stringent requirements of FDA CFR 175.300. It also was toxicologically evaluated to meet the NSF/ANSI 51.4.1 (2009) standard for food equipment materials.
Food grade certified epoxy EP42HT-2FG may be used across a wide variety of applications in the food industry, such as bonding and sealing metals, plastics, rubbers and other substrates, commonly found on food service 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 wide service temperature range of -60°F to +450°F (FDA certification done at the temperatures specified in the test protocol), EP42HT-2FG resists steam, radiation and frozen storage conditions.
With a volume resistivity of over 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 and Part B is amber) for its 100:30 mix ratio by weight. The recommended cure is 3-4 hours at 150-200°F. Alternatively, it can be cured at room temperature overnight followed by a 2-3 hour cure at 150-200°F.
EP42HT-2FG is available for use in half-pint, pint, quart, gallon and five gallon containers. It has a shelf life of one year when stored at room temperature in its original unopened containers.
