Master Bond Releases EP21ARHTND-2 Epoxy
Master Bond's EP21ARHTND-2 two-part epoxy adhesive is designed to withstand prolonged exposure to a wide range of chemicals.
Is said to be a reliable electrical insulator with a volume resistivity greater than 1014ohm-cm at 75°F, and dielectric strength of 440V/mil at 75°F for a 1/8-inch test specimen. Also features a tensile strength of 9,000-10,000psi, and a Shore D hardness of 75-85. Provides good heat resistance and is serviceable from -60°F to +400°F. Is capable of curing at room temperature, but to optimize its acid resistance properties, a cure schedule of overnight at ambient temperatures, followed by a heat cure of 150-200°F for 2-4 hr. or longer is typically recommended. Does not contain solvents and is RoHS compliant. Is said to bond well to metals, ceramics, composites, rubbers and plastics, and features a smooth paste-like consistency and will not flow or sag once applied, making it ideal for bonding and sealing applications.
