It fills the microscopic air gaps between mating metal parts so heat moves through the joint instead of stalling at it.\u003c\/p\u003e\n\n\u003ch2\u003eIt Is Not a Lubricant\u003c\/h2\u003e\n\u003cp\u003eWorth saying plainly, because the name causes genuine confusion: thermal grease does not lubricate anything. It is a thermal interface material, and its only job is conducting heat between two surfaces that are clamped together. If you are after something for lead screws, rails or smooth rods, you want our \u003ca href=\"\/products\/lubricating-oil\"\u003eLubricating Oil\u003c\/a\u003e instead. Thermal grease on a lead screw does nothing useful, and lead screw grease inside a heater block is considerably worse.\u003c\/p\u003e\n\n\u003ch2\u003eWhy a Hot End Needs It\u003c\/h2\u003e\n\u003cp\u003eTwo machined metal surfaces never really touch. Up close the contact is a handful of high spots with air trapped in the valleys between them, and air is a poor conductor of heat. That matters most where the heater cartridge sits inside its block. A cartridge with air gaps around it has to run hotter to push the same heat into the nozzle, and that shows up as temperature swinging mid-print, sluggish heat-up, and occasionally a thermal runaway error that ends the job. A thin film of grease displaces the air and closes the gap.\u003c\/p\u003e\n\n\u003ch2\u003eWhere to Use It\u003c\/h2\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eHeater cartridge into the heater block.\u003c\/strong\u003e The important one, and the most common cause of unstable hot end temperatures\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThermistor into the block.\u003c\/strong\u003e Better contact means the temperature the printer reads is closer to the temperature the nozzle is actually at\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eHeatbreak into the heatsink and block\u003c\/strong\u003e, for consistent heat transfer across the threaded joint\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch2\u003eHow to Apply\u003c\/h2\u003e\n\u003cul\u003e\n  \u003cli\u003eLet the hot end cool completely and switch the printer off at the wall\u003c\/li\u003e\n  \u003cli\u003eClean old compound and residue from both surfaces with isopropyl alcohol\u003c\/li\u003e\n  \u003cli\u003eApply a thin film.
