2.5 W/m·K Thermal Conductive Grease

Inquiry

The ALOS-SILI-429 thermal grease is a highly efficient thermal grease made from advanced composite materials, designed specifically as a thermal interface material. Renowned for its excellent thermal conductivity and extremely low interfacial thermal resistance, it effectively fills the microscopic gaps between electronic components and heat sinks. This ensures the rapid and stable transfer of heat. The product maintains a stable paste-like consistency at room temperature, making it easy to apply without curing, dripping, or cracking. This guarantees a consistently reliable thermal path. It is ideally suited for a wide range of electronic cooling applications that demand superior thermal performance, reliability, and ease of use.

Properties

Stable thermal conductivity. With a thermal conductivity rating of 2.5 W/m·K, this grease ensures rapid heat transfer from the heat-generating source to the heat sink. This efficiency is crucial for maintaining optimal operating temperatures in electronic components.
Low interfacial thermal resistance. Thanks to its excellent wetting properties, ALOS-SILI-429 can fully fill the microscopic irregularities on contact surfaces. This significantly reduces thermal resistance at the interface, enhancing overall thermal performance.
Low volatility. The material is formulated to have an extremely low content of volatile compounds and can effectively protect sensitive electronic components.
Long-term reliability. The grease exhibits superb resistance to high and low-temperature cycling, as well as weathering. It maintains stable performance over extended periods, without drying out or hardening, ensuring consistent thermal management.
Eco-friendly composition. Compliant with RoHS and other environmental standards, ALOS-SILI-429 is safe and non-toxic. It is suitable for applications where environmental safety is a priority, supporting sustainable practices.

Directions for Use

Surface preparation: Begin by thoroughly cleaning the surfaces to be coated. Remove any oils, dust, and debris to ensure a flat and even interface. A clean surface is crucial for optimal heat transfer efficiency.
Even application: Apply the thermal grease manually using a spatula. Ensure the grease is spread evenly across the component's contact surface for maximum effectiveness.
Assembly and fixation: Carefully align and attach the heat sink to the component. Apply light pressure to eliminate any trapped air bubbles, ensuring full contact between surfaces.
Excess material cleanup: Use a lint-free cloth to wipe away any excess grease that may ooze from the edges. This step helps prevent contamination of the motherboard and other parts.
