characteristic GD900 thermal paste Proportion: 2.3 G/Cc Thermal conductivity: 4.8 W/MK Working temperature: -58~392 degrees Fahrenheit Product features: Comply with RoHS and REACH environmental protection requirements. High thermal conductivity, high insulation, high temperature resistance, low oil content, non-corrosive. Working principle: Fill the gap between the heating element and the cooling device; increase the contact area to achieve the best heat conduction effect. How to use: A small amount of silicone oil floating on it is normal. Please stir well before use. Keep the coating surface clean and apply directly with tools (such as scrapers, finger cots, etc.). Reminder: Keep children away from it. If swallowed or accidentally get into the eyes, ears, nose, mouth, please rinse with water or send to the hospital if necessary. Storage: Store at room temperature. Please cover it after use to avoid impurities such as dust that have an adverse effect on thermal conductivity.
