Master Bond‘s EP42HT-2FG Black is a two-part, moderate heat-cured epoxy with high-temperature resistance that complies with FDA 21 CFR 175.105 for indirect food contact applications.
This epoxy withstands exposure to a range of harsh chemicals, including acids, bases, and solvents. It possesses good flow properties and can be employed for bonding, sealing, potting, and casting.
This new compound has a relatively long working life of 105 to 150 minutes for 100 grams of the mixed material at 75° F. The color of Part A is black, and Part B is light amber, with a mix ratio of 100 to 30 by weight.
EP42HT-2FG Black cures optically opaque, and the recommended cure schedule is overnight at room temperature, followed by a heat cure at 150° to 250° F for three to four hours.
This thermally stable system offers a glass transition temperature of 145° to 150° C and is serviceable over a wide temperature range from -60° to 450° F. It has a high tensile strength of 11,000 to 12,000 psi at room temperature and a tensile modulus of 400,000 to 450,000 psi. It’s electrically insulative with a volume resistivity greater than 1014 ohm-cm and a dielectric constant of 4.6 at 60 Hz, at room temperature. These attributes make EP42HT-2FG Black suitable for potting and encapsulation type applications.
The system is recommended for indirect food applications particularly where the surrounding environment may be exposed to aggressive chemical washdowns or antibacterial agents. It is available in 1/2 pint, pint, quart, and gallon kits. Specialty packaging is also available in premixed and frozen syringes.
Master Bond EP42HT-2FG Black is a two-component, moderate heat-cured epoxy system that offers chemical resistance to a range of bases and solvents. It’s notable for complying with the FDA 21 CFR 175.105 requirement for indirect food contact and can thereby be used in food processing applications and assembly.
