Product Description
- 1:1 mixing ratio; curable at room temperature or via heat-assisted curing.
- Excellent fluidity, insulation, and thermal shock resistance.
- Soft, low hardness
- Manual dispensing: To use, unscrew the nozzle cap, attach the static mixing tube, and then clip the glue tube onto the AB glue gun’s latch. Firmly squeeze the glue gun to mix the A and B components evenly through the static mixing tube. In line with the thermal dissipation structure design, dispense the uniformly mixed thermally conductive adhesive onto the heat-generating area and allow it to fully cure for 12 hours.
- Automatic dispensing: After unscrewing the nozzle cap, slide the glue tube onto the dispensing machine’s cartridge and then screw it onto the dispensing machine. Refer primarily to the dispensing machine’s operating instructions.
- Storage conditions: Temperature 5~35℃; Humidity 0~75%
- Shelf life: 12 months
- Packaging specifications: 50 mL, 400 mL
- Choosing the right thermal conductive gel requires considering several aspects. Here are some key factors:
- Thermal conductivity is measured in W/m·K. The higher the value, the stronger the material's ability to conduct heat. However, it’s important to note that a high thermal conductivity often comes with increased costs. Therefore, you should select an appropriate grade based on the device’s heat generation and cooling requirements—there’s no need to unilaterally pursue the highest possible values.
- Thermal resistance: Its unit is ℃·in²/W or ℃·cm²/W. The lower the thermal resistance, the better. It comprehensively reflects both the intrinsic thermal conductivity of the material itself and its thermal conductance at the interface with adjacent materials; sometimes, it’s even more important than the thermal conductivity coefficient itself.
- Viscosity and Fluidity: These factors influence how easy it is to dispense the material, whether it can fully fill tiny gaps, and whether it tends to sag or drip. The choice should be based on the size of the gap and the dispensing process (manual or automated). Curing Characteristics: For two-component gels, it’s important to pay attention to curing conditions (room temperature or heating), working time, and the time required for complete curing.
- Thixotropy and Anti-Sagging Properties: Good thixotropy means that the gel becomes thinner and easier to apply under shear force, yet thickens and resists flow once it’s stationary—this is particularly important when applying coatings onto vertical or inclined surfaces.
- Long-term Reliability (Quality Assurance): Temperature Range: Ensure the gel maintains its performance under both high and low operating temperatures of the equipment—for example, some applications require a range of -40℃ to 200℃.
- Durability and Stability: Pay attention to its resistance to aging, thermal shock cycle resistance, and whether it tends to dry out or become oily. Two-component gels generally perform better in terms of long-term reliability.
- Electrical Insulation: In most applications, gels are required to have good electrical insulation properties to ensure stability. However, there are also specially designed conductive thermal conductive gels available for specific applications.
- Other requirements may also include flame retardancy (e.g., UL94 V-0) and environmental compliance (e.g., RoHS, REACH).
- Interface and System Matching (Effectiveness): Interface Contact Pressure: Proper installation pressure helps expel air and reduce contact thermal resistance.
- Radiator performance: The radiator’s own heat dissipation capability must match the power of the heat source. If the radiator’s performance is insufficient, even using a gel with an extremely high thermal conductivity may result in only a very limited improvement in overall cooling effectiveness.
- Construction thickness: Under the premise of adequately filling the gap, the thinner the adhesive layer, the lower the thermal resistance typically is. It is recommended to apply the thermally conductive gel in a thin layer, with a thickness controlled within the range of 0.1 to 1 mm.
- Decisions can be made quickly based on the following core questions:
- 1. Does the product require subsequent maintenance or upgrades?
- Yes → Prioritize single-component products. Their non-curing properties make disassembly and cleaning extremely convenient.
- No → Give priority to two-component systems. After curing, they offer more durable and stable mechanical and thermal conductivity properties.
- 2. What are the expected service life and operating environment of the product? For long lifespans (>5 years) and harsh environments (wide temperature fluctuations and high vibration), prioritize two-component formulations. Their crosslinked curing structure offers superior resistance to aging, sagging, and performance degradation. For short lifespans and mild environmental conditions, a single-component formulation is sufficient to meet requirements, while also being more cost-effective and simpler to process.
- 3. What is the required fill volume or thickness of the application? For large fill volumes (e.g., >2 mm) or thick adhesive layers, a two-component system must be used. A single-component system carries a high risk of oiling out, shrinkage, or even drying out over time when applied in thick layers. For thin-layer fills (e.g., <1 mm), either system can be used; further evaluation should take into account the considerations outlined in Questions 1 and 2.
- Features: Typically does not cure (though single-component formulations for special applications can be cured), remains consistently moist, and has a relatively high oil bleed rate.
- Advantages: Easy to use—no mixing required; easy to rework and repair; achieves high compression ratios even at very low pressures, reducing stress on components.
- Disadvantage: Under long-term use, it may be slightly less reliable than two-component adhesives due to issues such as oil bleed rate.
- Features: After mixing components A and B, a curing reaction occurs, forming an elastomer with low oil bleed rate.
- Advantages: Superior long-term reliability and better resistance to sagging (more stable shape after curing), making it suitable for large-volume applications (e.g., electric vehicle battery packs).
- Disadvantages: Requires mixed use, making the operation slightly more complex; after curing, rework may be somewhat more difficult compared to single-component systems.
