Technical Data Sheet LOCTITE TCF 4000 PXF April-2014 PRODUCT DESCRIPTION LOCTITE TCF 4000 PXF provides the following product characteristics: Technology Phase Change Appearance Gray Application Method Manual application Product Benefits ● Low thermal resistance ● Non silicone ● No pump-out, dry-out or pull-out Phase change temperature 45 °C Application Thermal management Typical Assembly Thermal grease replacement in computing applications, Lidded and bare die processor applications and Used between any heat generating electrically isolated component and a heat sink LOCTITE TCF 4000 PXF is a reworkable phase change thermal interface material suitable for use between a heat sink and variety heat dissipating components. The material flows at the phase change temperature, conforming to the surface features of the components. Upon flow, air is expelled from the interface, reducing thermal impedance, performing as a highly efficient thermal transfer material. Custom parts are also available upon request with low cost tooling.

Currently supplied in two compound thicknesses, multiple thicknesses will soon be available to match surface finishes and flatness considerations in the interface area. LOCTITE TCF 4000 PXF is completely reworkable without solvents and is easier to remove than previous formulations. If a clean surface is required, any compound present can easily be removed with mineral spirits. No silicones are utilized in the formulation of the phase change compound. Unlike previous versions of Powerstrate, LOCTITE TCF 4000 PXF does not require adhesive edge strips for heatsink attach applications. The "tacky" nature of the product allows for it to naturally adhere to the heatsink surface. Storage Store product in the unopened container in a dry location. Storage information may be indicated on the product container labeling.
