USG149 is a flexible epoxy adhesive for sealing or encapsulating electronic devices. It is a two-component, flowable formulation that cures at room or elevated temperature to provide strong bonding to various plastics, ceramics and metals. The flexibility reduces thermal stress and provides better thermal cycle performances. USG149 is dispensable.
