Storage

ET 1608 has a shelf life of at least 6 months when stored below 25°C in the originally sealed container. The 'Best use before end' date of each batch appears on the product label. Storage beyond the date specified on the label does not necessarily mean that the product is no longer usable. In this case however, the properties required for the intended use must be checked for quality assurance reasons.

Characteristic

ET 1608 is a thermally conductive epoxy adhesive for electronic applications. It is two components with 2:1 mixing ratio, and can be cured at room temperature or elevated temperature after mixing. It provides strong bonding to metals such as aluminum, copper, plastics, FR4 PCBs, ceramics, glass, etc, with excellent thermal conductivity. The cured material also has very low CTE that can provide better thermal cycle performances. ET 1608 is dispensable.

Processing Instruction

Important! Only components A and B with the same lot number may be processed together! For the package in a container (not in a cartridge), to ensure homogeneity of the material, the components must be stirred thoroughly before they are removed or processed in order to uniformly disperse any fillers that might have settled during storage. For long-term storage, it is recommended to store the material in –40°C freezer to prevent filler from settling.. We recommend running preliminary tests to optimize conditions for the particular application. Comprehensive processing instructions can be obtained by contacting directly to United Adhesives, Inc.
