Loctite 384 Thermally Conductive Acrylic Adhesive 25ml

Loctite 384 Thermally Conductive Acrylic Adhesive White 25ml is a medium-strength off-white thermally conductive acrylic adhesive engineered for maximum efficacy in bonding heat-generating components to heat sinks. This industrial-grade adhesive permanently bonds components, preventing costly thermal degradation or component failure caused by poor heat dissipation. Whether you are securing transformers or transistors, this premium modified acrylic paste provides a robust, heat-dissipating seal on all electrical assemblies—including printed circuit boards and metal heat sinks.

Why Choose Loctite 384 Thermally Conductive Acrylic Adhesive?

• Excellent Heat Dissipation: The high thermal conductivity provides exceptional heat transfer for thermally sensitive components.
• Controlled Strength: Offers a medium-strength hold that secures parts firmly during operation but permits clean field and service repairs.
• Thermal Cycle Resistance: Maintains bond integrity under harsh conditions, showing zero loss in strength after 1,000 hours of thermal cycling from 15°C to 100°C.
• Ideal for Electronic Assemblies: Perfect for heavy-duty electronic manufacturing, specifically designed for transformers, transistors, and other heat-generating components.
• Easy Device Removal: Components can be safely removed or repaired while hot using a hot air jet, as bond strength decreases at temperatures between 65°C and 93°C.

Technical Specifications

• Product Type: 1-part, thermally conductive, modified acrylic paste adhesive

Simple Application Instructions

1. Clean: For optimal results, ensure all bond surfaces are clean and free from grease.
2. Apply Activator: Use an applicator to apply Loctite Activator 7387™ to one of the surfaces to be bonded. Allow the solvent to evaporate; the active ingredients will remain active for up to 2 hours.
3. Apply Adhesive & Assemble: Apply the adhesive to the unactivated surface. Secure the assembly, minimizing air entrapment within the bondline. Wait approximately 5 minutes for the adhesive to fixture before handling. Full cure occurs within 4 to 24 hours.

Frequently Asked Questions (FAQ)

What is Loctite 384 used for?

Loctite 384 is a medium-strength thermally conductive acrylic adhesive designed for bonding heat-generating components to heat sinks. It is specifically formulated to prevent thermally sensitive components from overheating or failing due to poor heat transfer.

Can Loctite 384 be disassembled?

Yes. Because it features a controlled medium strength, components or devices bonded with Loctite 384 can be disassembled for service or repair. Disassembly can be performed cleanly by using a hot air jet on the components while they are hot, since the bond strength naturally decreases at elevated temperatures between 65°C and 93°C.
