Product Description
Honeywell HLT 3500 is a two-part hybrid gel product, dispensable and thermally conductive, which offers long-term reliability and superior softness. It exhibits low contact resistance, minimal oil bleeding at high temperatures and has very low thermal impedance under pressure. A balanced solution for vertical mounting that requires high TC before we go into the upper end of the product line. The enhanced bonding force between the polymer base and the filler largely improves the thermally conductive gel oil separation issue in storage. Prior to curing, the material maintains good thixotropic characteristics and low viscosity to be easily dispensed.
Related Product:
One-part hybrid gel does not requires curing, check HT3500. HT3500 shares the same thermal properties as HLT3500. However, some process properties are difference. Check the comparison between one-part and two-part hybrid thermal gel.
Key Features：
- Low contact resistance, BLT 0.1mm~5mm (TI vs Pressure curve)
- Easy to dispense (>100 g/min rate) and rework (with acetone, IPA or toluene)
- High compressibility for low stress applications (Thickness vs Pressure table)
- Long-term reliability, less oil separation, and low outgassing (<0.5%)
- No pump out, slump out and cracking
- Up to 200 °C applicable temperature
Typical Applications:
- Consumer electronics - gaming systems, portable devices
- Telecommunications equipment - routers, servers, memory modules, hard disk drives, solid state drives
- Automotive and aerospace - EV battery, power modules, capacitor cooling, lighting, charging units, ADAS
Curing Schedule:
HLT3500 can be cured at either 18 hours @room temperature or 30 minutes @100°C. You can optimize curing parameters for your own application needs. Check HLT Application Note to know storage and dispensing suggestions.

Additional Information
HLT3500 Thermal Performance
HLT 3500 exhibits great Thermal impedance the more pressure you apply. At least 10psi pressure is suggested while applying it.
Additionally the oil bleeding is minimal. The test has been conducted by pasting a 25.4 x 25.4 x 1.5mm sample on A4 paper, either at Room temperature or at 125oC
Comparison between one-part and two-part hybrid gel
The HT series is one-part hybrid gel, which is already fully cross-linked before being applied. It could save time in assembly process and has longer shelf life. The HLT series products are two-part hybrid gels that can be cured in short-time after two-component mixing at room temperature. HLT products are cured in place, thus have better adhesion to components and are suitable for both horizontal and vertical applications. In total, the two series products share similar thermal and electrical properties.
