TIM Gel (Two Part)


Brief Introduction

Flextein MG SERIES is a thermally conductive liquid gap filling material two-component, cured either at room or elevated temperature. Prior to curing, the material maintains good thixotropic characteristics, and is easy to dispense. The result is a soft, form-in-place elastomer ideal for combining fragile components with high topography and / or stack-up tolerances to general heat sink or housing. After curing, it won't pump from the interface as a result of thermal cycling and is dry to the touch.
