Thermal Grease Silicone Grease is metal-free and non-electrical conductivity, eliminating the risk of strong thermal conductivity, short-circuit, and enhances the protection of your CPU and VGA card. It can also protect other precision equipment such as IC better Use a small syringe to apply silicone greases, and a scraper at the bottom is convenient for debugging. The clean design makes it very easy to use even for beginners. (The silicone grease will harden when exposed to sunlight for a long time, so it is recommended to store it in a cool place away from direct sunlight. (Can be refrigerated and not freezed.)
If there is anything after you receive the product, please feel free to contact us at any time. After using the silicone grease, the packaging bags and tubes can be stored for a long time. Bags can be sealed after opening. Small black lids can be sealed for storage
Highly durable, 3KS grease will not damage over time. No need to use repeatedly after one use. Silicone grease maintains stable properties without hardening for a long time. It is non-conductive, so you don't have to worry about short circuits
High quality silicone grease Thermal conductive grease Product Specifications Thermal conductivity: 16W/m·k Heat resistance: -50°C to 350°C Color: Light gray Thermal resistance: 0.05°C cm²/W Thermal Conductivity: 16W/m·k, Density: 3.42g/cm³, Grease Capacity: 10g (4.2ml) (Thermal paste is more denser than water and does not match grams and milliliters. )
