Thermal Adhesive Silicone Compound – Heatsink Bonding Glue 5g
Thermal Adhesive Silicone Compound – Heatsink Bonding Glue 5g
Thermal Adhesive Silicone Compound – High-Strength Heatsink Bonding Glue
Keep your PC, GPU, and electronics running cool with this professional-grade thermal adhesive silicone compound. Designed for builders, modders, and technicians, this 5g viscous thermal glue delivers a fast, firm bond between heatsinks, LEDs, components, and other electronic parts — no mechanical fasteners required. Made in Mainland China.
Why Choose This Thermal Adhesive?
- High-Strength Bond: Room-temperature vulcanizing (RTV) silicone formula creates a firm, elastic, long-lasting bond superior to standard double-sided thermal tape.
- Excellent Thermal Conductivity: Efficiently transfers heat from components to heatsinks, helping maintain optimal operating temperatures for CPUs, GPUs, LEDs, and more.
- Wide Temperature Range: Rated from -60°C to 200°C, with short-term resistance up to 300°C — suitable for demanding environments.
- Fast Surface Cure: Begins curing quickly at room temperature; higher ambient humidity and temperature accelerate the cure time.
- Electrically Insulating: Safe for use directly on circuit boards and sensitive electronics without risk of short circuits.
- Non-Toxic Formula: Safe for handling and application across consumer and professional electronics.
- Airtight Vacuum-Sealed Packaging: Each 5g tube is sealed in a vacuum jacket bag to extend shelf life and keep the compound fresh until you're ready to use it.

How to Use
- Clean surfaces first: Wipe all bonding surfaces with isopropyl alcohol. Avoid detergent-based cleaners. Allow surfaces to dry completely before applying.
- Apply the compound: Squeeze a thin, even layer directly onto one surface. Aim for 0.1–0.5mm thickness — thinner layers conduct heat more efficiently.
- Press and hold: Firmly press the components together. Higher ambient temperatures and humidity will speed up curing.
- Seal immediately: Replace the cap right away after each use to prevent the compound from curing inside the tube.
Compatible Applications
- PC & GPU heatsink mounting
- LED chip bonding and heat dissipation
- Power transistor and IC heat management
- Electronic instruments and sensor housings
- General electronic component insulation and sealing

Frequently Asked Questions
Q: Is this thermal adhesive electrically conductive — could it short-circuit my components?
A: No. This thermal silicone adhesive compound is electrically insulating, not conductive. It safely transfers heat while preventing electrical shorts, making it ideal for direct application on PCBs, LED boards, and other sensitive electronic components.
Q: How long does the thermal adhesive take to cure fully?
A: Surface curing begins quickly at room temperature. Full cure time depends on ambient temperature and humidity — warmer, more humid conditions speed up curing. For best results, allow at least several hours before subjecting the bond to thermal stress.
Q: Can this compound be used instead of standard thermal paste for CPU/GPU cooling?
A: This product is a bonding adhesive designed to permanently (or semi-permanently) secure heatsinks to components. It provides thermal conductivity alongside a strong physical bond. Unlike standard non-adhesive thermal paste, it is not designed to be easily removed. It's ideal when you need the heatsink to stay firmly fixed without clips or screws.
Q: What is the shelf life, and how should I store this compound?
A: The vacuum-sealed airtight packaging extends shelf life significantly. Store in a cool, dry place away from direct sunlight. Always reseal the tube tightly immediately after use to prevent premature curing and maximise shelf life.
