TGR series is a high-performance thermal grease based on silicone resin, designed to provide excellent heat dissipation. With superior wetting characteristics, it effectively fills the irregular micro-structures on component surfaces, forming an interface with very low thermal resistance. The grease is highly reliable, and it will not dry, precipitate, or harden over time. Its typical coating thickness ranges between 0.05 to 0.15mm.
TGR is ideal for addressing heat dissipation challenges in general components. In its viscous liquid form, it evenly fills gaps on the surfaces of components, ensuring optimal thermal transfer. With low thermal resistance, it can be applied via silk screen printing or squeegee coating onto heat sinks or thermal modules. Additionally, the material is RoHS compliant and meets other environmental standards, making it safe for both components and the environment.
