TIG780-38S — Product overview
TIG™780-38S Is the use of environmentally safe thermal silicone grease, with good agitation and thixotropy. When the external force is applied, the consistency of the silicone grease decreases, showing a good stirring ability. However, after the removal of the external force, the silicon grease is in a static state, and the consistency of the silicone grease increases, showing good thixotropy and no flow drawing phenomenon. The thixotropic thermal conductive silicone grease has better scratch and coating property in the use process, will not appear the hanging phenomenon, is more conducive to the operation of the glue, has good fine and thermal conductivity, and has the advantages of good storage stability
