Arctic Silver Ceramic Thermal Epoxy is a permanent, high-performance thermal adhesive engineered for securely bonding heatsinks to electronic components where traditional mounting hardware cannot be used. Designed with a two-part epoxy system, it combines strong mechanical adhesion with efficient thermal conductivity to ensure reliable heat transfer and long-term stability.

Formulated with aluminum oxide and boron nitride ceramic fillers, this epoxy delivers excellent thermal performance while remaining electrically insulating. Once cured, it forms a durable, permanent bond ideal for attaching heatsinks to CPUs, GPUs, RAM modules, voltage regulators, chipsets, and other integrated circuits.

This 6-gram set includes two 3 g Luer slip syringes (Part A and Part B) with a simple 1:1 mixing ratio for precise and controlled application.

Key Features

• Two-part thermally conductive ceramic epoxy (Resin A + Hardener B)

• Filler: Aluminum Oxide & Boron Nitride

• Electrically insulating formula for safe use on PCBs

• Permanent, high-strength bond after curing

• Ideal for heatsinks on CPUs, GPUs, RAM, VRMs, and ICs

• Easy 1:1 mixing ratio

• Supplied in dual 3 g syringes (6 g total)

Technical Specifications

• Type: Two-part thermal epoxy

• Mix Ratio (A:B): 1:1

• Dispenser: Luer slip syringes

• Cure Temperature: 25°C (77°F)

• Handling Strength: Approx. 5 minutes

• Full Cure Time: 24 hours

• Electrical Conductivity: Electrically insulating

Application Instructions

1. Ensure both surfaces are clean, dry, and free from grease or residue (use isopropyl alcohol if necessary).

2. Dispense equal parts of Resin (A) and Hardener (B).

3. Mix thoroughly at a 1:1 ratio until uniform.

4. Apply a thin, even layer to one surface.

5. Position heatsink carefully — bond is permanent once cured.

6. Allow approximately 5 minutes for initial handling strength and 24 hours for full cure.

Important Notes

• Permanent adhesive – not intended for temporary mounting.

• Do not apply excessively thick layers.

• Use gloves and avoid skin or eye contact.

• Store in a cool, dry place with caps sealed tightly after use.

Arctic Silver Ceramic Thermal Epoxy is the ideal solution when mechanical mounting isn’t possible and long-term, reliable thermal bonding is required.
