樂泰 382

產品概覽

LOCTITE 382 is a one-component, high-viscosity instant adhesive gel developed for precision bonding in electronics and industrial applications. With its ultra-clear gel consistency, it is particularly suited to tasks such as wire tacking to coil-forms, mounting standoffs or edge guides to circuit boards, and securing small hardware where controlled flow is essential. It cures rapidly (20-40 seconds) upon confinement and humidity, forming strong adhesion on metals, rubbers and common plastics—and, when used with primer (e.g., LOCTITE® SF 770), on difficult-to-bond plastics like polyolefins.

主要功能與優勢

• High-viscosity gel so adhesive remains in place and avoids run-off on vertical or small surfaces.

• Rapid fixture — typically 20-40 seconds, enabling quicker assembly throughput.

• 廣泛的基板相容性 — bonds metals, rubbers, many plastics; with primer can also bond low-energy plastics.

• Ideal for electronics/precision use — e.g., wire tacking, component mounting, tamper proofing.

• Ultra-clear cured appearance — good for visible assemblies where clarity matters.

申請

1. 表面處理： Clean all mating surfaces thoroughly — remove grease, oil, dust and old adhesives. Use an appropriate cleaning agent.

2. Primer / Activator (if needed):

   • For low-surface-energy plastics (PP/PE) use LOCTITE® SF 770 or SF 7239 primer.

   • For faster cure on difficult surfaces or larger gaps you may apply suitable activator (e.g., for wire tacking kits) — per datasheet.

3. 應用： Apply a small amount of LOCTITE 382 to one surface (because of the gel viscosity, more precise dispensing may be needed for small parts).

4. Assembly: Join parts immediately after applying adhesive. Due to the short fixture time (~20-40 s), ensure alignment is correct on first placement.

5. 固化／處理： Allow assembly to remain undisturbed until initial fixture is achieved; full strength typically develops over 24 h.

6. 拆卸／維修： For bonded parts requiring removal, refer to the SDS/TDS for recommended methods; generally mechanical separation and/or heat may be required.
   提示： Avoid over-application to prevent adhesive flash; use minimal quantity in tight assemblies. Ensure proper gap control (≤0.15 mm) for optimal performance.

常見問題

• Q: What is the typical fixture time for LOCTITE 382?
  A: Approximately 20 to 40 seconds under standard ambient conditions.

• Q: Can LOCTITE 382 bond polyolefin plastics like PP or PE?
  A: Yes — when used in conjunction with primer LOCTITE® SF 770 or SF 7239 for low-energy surfaces.

• Q: What gap size is acceptable for bonding?
  A: Up to about 0.15 mm is suitable for optimal strength and cure.

• Q: Is this adhesive suitable for electronics/PCB applications?
  A: Yes — LOCTITE 382 is designed especially for electronic assembly tasks such as wire tacking and component mounting.

• Q: What precautions should be taken during use?
  A: Because it cures rapidly and bonds skin and materials in seconds, work carefully, use protective gloves/eye protection, and provide good ventilation. Refer to SDS for detailed hazard information.
