EP42HT-2ND2MED (Black) is an excellent electrical insulator with a volume resistivity over 1012 ohm-cm, a thermal expansion coefficient of 35 to 40 in/in x 10-6/°C, a dielectric constant of 3.8, and a tensile strength exceeding 12,000 psi at ambient temperatures. Heat resistant up to 450°F, it also withstands chemicals such as inorganic and organic acids, alkalis, organic solvents, and aromatic hydrocarbons.
This epoxy conveniently cures at room temperature in 48 to 72 hours. Its optimal curing schedule is overnight at room temperature followed by 2 to 3 hours of heat curing at 100°C to 125°C. EP42HT-2ND2MED (Black) has a noncritical mix ratio of 100:40 by weight or 100:50 by volume, and a paste consistency with minimal flow when applied. It offers a lengthy working life of 30 to 45 minutes for a mixed 100 gram batch at ambient temperatures, which can be increased by using shallow mixing vessels or mixing smaller batches. Parts A and B for EP42HT-2ND2MED (Black) are available for use in syringes, half pints, pints, quarts, gallons, and five gallon containers.
Medical grade EP42HT-2ND2MED (Black) offers high temperature resistance and high strength for bonding, sealing, and coating applications. This non-drip adhesive features outstanding electrical insulative properties.
