Product Description

Master Bond Polymer System EP42HT-2FG Black is a two component epoxy for indirect food contact as per FDA specification 175.105. This flowable epoxy has an easy to use mix ratio of 100 to 30 by weight. After mixing, EP42HT-2FG Black has an exceptionally long working life of 105-150 minutes. The system can cure in 3-4 hours at 150-250°F. However, to optimize properties, the recommended cure schedule is overnight at room temperature followed by a post cure of 3-4 hours at 150-250°F. This system contains no solvents and has very low shrinkage upon curing.

EP42HT-2FG Black bonds well to a wide variety of substrates including metals, composites, ceramics, glass, plastics and rubbers. It is highly resistant to acids, bases, solvents, water, (including boiling water), as well as many other harsh chemicals. It is a robust thermal and electrical insulator. The system resists thermal cycling while retaining good dimensional stability. It has an attractive array of desirable physical properties including high tensile strength and modulus. Additionally, EP42HT-2FG Black has a high Tg with a service temperature range of -60°F to 450°F. The color of Part A is black and Part B is amber clear. Also, this epoxy is lower exotherm and can be used for potting and encapsulation. EP42HT-2FG Black should be considered for indirect food applications particularly when the surrounding environment is aggressive.
