Characteristics EP1611 is a flexible epoxy adhesive for sealing or encapsulating electronic devices. It is a twocomponent, non-slump, rubber-toughened formulation that cures at elevated temperature to provide strong bonding to various plastics, ceramics and metals. The flexibility reduces thermal stress and provides better thermal cycle performances. EP1611 is dispensable.
- Special Features & Benefits
- Flexibility for stress reduction
- Fast cure and room temperature curable
- Flowable for potting / encapsulation
- Strong fracture toughness
- Strong bonding to various substrates
- Low bleeding, low volatile

- Processing Instruction
- 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 potting applications, it is recommended to warm the parts to ~60°C, and then do potting. Any possible air bubbles in mixing or potting process can be removed by vacuum.
- 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.

- Safety
General hygiene regulations should be observed.
Storage & Handling
- Storage
EP1611 has a shelf life of at least 12 months when stored in ambient 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.
