Overview
Rave Scientific offers M-Tec conductive silver epoxies enable embedding and cementing samples and parts providing high conductivity and good mechnical strength. When the epoxy is cured, the sample can undergo further preparation steps such as polishing, lapping, thinning, etc. The epoxies are not suitable for soldering, but create conductive contact. The EM-Tec silver filled epoxies are a two component system supplied in two syringes. To improve conductivity and to make mixing easy, both components are silver loaded. The amounts of the EM-Tec silver epoxy sets are chosen for affordability, yet sufficient for experiments, sample preparation and prototyping. The EM-Tec range of high-end silver filled conductive epoxies include:
EM-Tec AG 30 long pot life, extreme conductivity silver filled epoxy
EM-Tec AG30 conductive silver filled epoxy combines excellent conductivity, good thermal conductivity, good mechanical strength, long pot life and relatively low curing temperature. Excellent choice for high end applications where excellent conductivity is needed. The low curing temperature of 65°C provides compatibility with temperature sensitive materials or devices. Easy mixing ratio of 1:1 by volume
EM-Tec AG 31 fast setting, conductivity silver filled epoxy
EM-Tec AG31 is a fast setting silver filled epoxy and ideal when time is the limiting factor. Gives 10 minutes working window and cures in 15 minutes at the relatively low curing temperature of 65°C. Conductive and mechanical properties will be suffcient for most for non-critical applications. The Em-Tec AG31 represents the most economical silver filled epoxy. It should not be used for applications where shrinkage is a limiting factor.
EM-Tec AG 32 long pot life, high conductivity silver filled epoxy
EM-Tec AG32 conductive silver filled epoxy is an all-round long pot life type epoxy for applications where extreme conductivity and/or highest thermal conductivity are not needed. It is the strongets of the three epoxies and should be used where mechanical strength is needed. Best conductive epoxy for cross sectioning.
