HY410 10g White Thermal Conductive Grease Silicone Paste

Product Overview

The HY410 White Thermal Conductive Grease is a professional-grade silicone-based thermal interface material (TIM) engineered to optimize heat transfer between high-power electronic components and their respective heatsinks, heat spreaders, or liquid cooling blocks. Formulated with a precise matrix of micro-fine metal oxide particles suspended in high-stability silicone fluid, HY410 effectively displaces microscopic air pockets and surface irregularities at the mating interface. By minimizing interfacial thermal resistance, this compound ensures continuous, high-efficiency heat transfer, preventing localized thermal throttling and extending the operational lifespan of sensitive semiconductor devices.

Technical Specifications and Material Characteristics

Engineered for demanding thermal management challenges, HY410 boasts a thermal conductivity rating exceeding 1.42 W/m-K coupled with a low thermal impedance of less than 0.252 degree C-in2/W. The compound retains its optimal consistency, viscosity, and dielectric properties across a broad operating temperature range of -30 degrees Celsius to 300 degrees Celsius. Crucially, HY410 is electrically non-conductive, offering high dielectric breakdown resistance to eliminate the risk of short circuits across dense PCB traces, surface-mount components, or exposed microchip pins. Its non-curing, non-drying, and non-bleeding formulation guarantees long-term performance stability without phase separation or hardening under continuous, severe thermal cycling.

Target Applications and Integration Use-Cases

Packaged in an ergonomic 10g applicator syringe with an included plunger, HY410 allows for accurate, clean, and controlled dispensing across varied hardware platforms. It is ideally suited for desktop CPU integrated heat spreaders (IHS), graphics processing units (GPUs), laptop thermal modules, high-output LED arrays, power MOSFETs, voltage regulator modules (VRMs), solid-state relays (SSRs), motor drivers, automotive electronic control units (ECUs), and 3D printer hotend heater blocks. Whether deployed in automated industrial control systems, server arrays, or custom PC hardware builds, HY410 provides reliable interface cooling for high-density electronic assemblies.

Application Guidelines and Compatibility

To achieve peak thermal dissipation efficiency, contact surfaces must be thoroughly cleaned of old residue, oil, and dust prior to application. Dispense a minimal amount onto the center of the component surface; mechanical pressure applied during heatsink installation will spread the paste evenly across the entire surface area, creating an ultra-thin bond line. The non-corrosive chemical profile ensures complete safety and material compatibility with aluminum, copper, nickel-plated copper, and ceramic substrate materials.
