Thermally Conductive Epoxies and Thermally Conductive Grease - OMEGA - #1

Text version of the page

Epoxies and Thermally Conductive Pastes OMEGABONDTM epoxy and OMEGATHERMTM thermal conducting pastes are high temperature and high thermally conductive epoxies and silicone products. They are specially formulated for permanent and temporary bonding of thermocouples, thin film RTDs, thermistors and other temperature sensors. The pastes are also formulated to most surfaces–metals, ceramics, glass, plastics, and paper products. OMEGABONDTM and OMEGATHERMTM products are compounded and packaged for convenient, easy mixing and application. Each formulation exhibits important characteristics necessary for accurate, fast, reliable temperature measurement. These are: good adhesion and strength, high temperature rating, high thermal conduction, high electric insulation, thixotropic consistency, fast cure, and easy application. To assist in your selection, a summary of each product’s properties are shown in the accompanying table. “Twin pak” packaging is supplied to ensure the user with accurate proportioning of resin and catalyst, as well as to provide a clean, fast means of mixing. The “Twin Pak” is a flexible, transparent plastic pouch, separated into two isolated compartments by means of a removable external divider. In one compartment is the resin, in the other compartment is the pre-measured catalyst. To use, remove the divider, mix the two components by kneading the pouch, then snip-off a corner to dispense. Each “Twin Pak” comes with an instruction sheet, enclosed in a clear, heat-sealed plastic envelope.
