| New high temp thermally conductive epoxy  Aremco Products introduced Aremco-Bond 805, a new high temperature, thermally conductive epoxy system. Aremco-Bond 805 is a two component, 100% solids, aluminum-filled, epoxy ideal for bonding, potting and tooling applications to 572ºF. Aremco-Bond 805 exhibits excellent adhesion to a variety of high temperature plastics such as polyimides and composites, as well as glass, ceramic, and high expansion metals. Aremco-Bond 805 is mixed in a ratio of 10 parts resin to 1 part activator by weight and cures at room temperature in 24 hours or at 200ºF in 2 hours.After curing, it exhibits a thermal conductivity of 12.5 Btu-in/hr-ft2-ºF and dielectric strength of 50 volts/mil. The tensile shear and flexural strengths are 1,800 and 15,500 psi, respectively. A linear shrinkage of .003 in/in and Shore D Hardness of 87 are exhibited. Aremco-Bond 805 is easily machined, drilled, tapped, or polished. Typical applications include the bonding of heat sinks and fins used in heat exchangers as well as producing vacuum molds, dies, drill jigs, injection molds, and other high temperature fixtures. Aremco-Bond 805 is supplied in pre-measured pint, quart, gallon and five gallon containers from stock. write your comments about the article :: © 2007 Construction News :: home page |
