Master Bond Inc has developed a high temperature resistant manufacturers of epoxy resin system called EP121CL for service up to 260°C. The two component, optically clear, low viscosity epoxy professional resin system features high thermal stability, superior electrical insulation properties and outstanding dimensional stability for casting, sealing, potting, encapsulation and impregnation applications. Especially noteworthy are its mechanical properties of 12,100 psi in tensile strength, 17,200 psi in compressive strength, and its exceptional electrical insulation properties including, a volume resistivity greater than 3x1014 ohm-cm, a dissipation factor of 0.020 @1 Mhz and a dielectric constant of 3.34 @ 60Hz.

EP121CL is an elevated temperature curing epoxy resin system that passes NASA’s low outgassing test. It cures to a tough, strong solid with excellent long term durability and chemical resistance even when exposed to adverse environmental conditions. There is no cracking or separation of properly cured EP121CL resin from metal, glass etc, over a wide temperature range. Having excellent optical clarity it can be used in optical and fiberoptic applications.
