LOCTITE® 382 Instant Adhesive Ultra Clear 20g

LOCTITE 382 is a high-viscosity, water-white to slightly cloudy ethyl cyanoacrylate instant adhesive gel engineered for maximum efficacy in electronics applications. This industrial-grade adhesive permanently bonds and tacks components, preventing costly structural or electrical failure caused by component movement, vibration, or mechanical stress. Whether you are securing wire tacking to coil forms or mounting standoffs, edge guides, and stiffeners to circuit boards, this premium single-part adhesive provides a robust, impact-resistant bond on all rubbers, plastics, and metals—including difficult-to-bond substrates when paired with an activator.

Why Choose LOCTITE 382 Instant Gel?

• Rapid Component Tacking: Achieves rapid fixture times (e.g., 20 to 50 seconds on steel, 15 to 40 seconds on ABS) to ensure components remain securely positioned during assembly.
• Multi-Substrate Versatility: Exhibits exceptional bonding compatibility across a diverse range of materials, including metals, plastics, and various rubber compounds.
• High-Viscosity Gel Formula: The single-part, high-viscosity consistency prevents running and migration, making it highly effective for precise placements on circuit boards.
• Excellent Chemical & Solvent Resistance: Retains 100% of its initial bond strength after 1,000 hours of exposure to common industrial environments like motor oil, gasoline, isopropanol, and ethanol.
• Reliable Heat and Humidity Stability: Maintains 95% of its initial strength under continuous environmental stress, such as exposure to 95% relative humidity at 40°C.

Technical Specifications

Simple Application Instructions

1. Clean: For optimal results, clean all mating surfaces with a safe degreasing solvent to remove any dissolvable contamination, grease, or oil, and allow to dry completely.
2. Apply: Apply one coating of TAK PAK® accelerator to the bonding area if instant curing is required (allow 15–30 seconds to dry). Then, apply drops of the liquid LOCTITE 382 cyanoacrylate directly to the target area within 45 seconds.
3. Assemble: Assemble the parts quickly. Where possible, shift the surfaces slightly in relation to each other for a few seconds to ensure uniform distribution and maximum activation. Secure the assembly and allow it to reach fixture strength.

Frequently Asked Questions (FAQ)

What is LOCTITE 382 used for?

LOCTITE 382 is a high-viscosity instant adhesive designed primarily for specialized electronics assembly. It is specifically formulated to prevent delicate electronics components, wires, and adjusters from loosening or shifting due to environmental vibrations and operational shocks.

Can LOCTITE 382 be disassembled?

No, it forms a highly permanent bond. To break the cross-linked cyanoacrylate bond without damaging sensitive electronic substrates, mechanical shearing or specialized chemical debonding solvents are typically required, as it retains high hot-strength capacities up to 121°C.

Does LOCTITE 382 work on plastic and rubber surfaces?

Yes. LOCTITE 382 offers robust performance across a broad spectrum of plastics (like ABS, PVC, and Polycarbonate) and rubbers (such as Neoprene and Nitrile). It is highly effective on both rigid metallic surfaces as well as flexible polymeric components.

Is LOCTITE 382 safe for all environments?

While highly resilient against industrial chemicals and moisture, LOCTITE 382 is not recommended for use in pure oxygen or oxygen-rich systems. It should never be selected as a sealant for chlorine, strong acids, or other highly oxidizing materials.
