製品概要

LOCTITE 5188 is a one-part, form-in-place anaerobic gasketing sealant formulated for sealing rigid metal flanged connections—such as gearboxes, engine casings and housings—particularly where surfaces may have slight oil or residue contamination. It cures between close-fitting metal faces in the absence of air to form a flexible, durable gasket that resists vibration, chemical attack, and thermal cycling. It is especially suitable for aluminum and steel flanges.

主な機能と利点

  • Excellent flexibility even after exposure to elevated temperatures — maintains seal integrity under movement and thermal cycling.

  • Oil-tolerant formulation — designed for flanged joints with minor contamination, avoiding costly cleaning or re-machining.

  • High chemical resistance — safeguards assemblies against fluids, oils and harsh conditions.

  • Works on aluminum and steel flanges — engineered adhesion for active and passive metal substrates.

  • Instant low-pressure seal on assembly — reducing downtime and enabling quicker commissioning.

申請

  1. 表面処理： Remove loose material, old gasket material, heavy oils or coatings; wipe surfaces clean.

  2. アプリケーション： On one flanged surface, apply a continuous bead of LOCTITE 5188 close to bolt holes; ensure coverage around the flange.

  3. Assembly: Bring mating flange faces together and tighten to specified torque. Wipe off any visible squeeze-out before curing.

  4. 硬化／取り扱い： The product begins cure when air is excluded; initial handling strength is reached in ~25 minutes on steel. Full cure strength develops over time as per the TDS.

  5. 分解／修理： Flanged joints sealed with LOCTITE 5188 may be disassembled using standard mechanical methods; if removal is required, gentle heating or solvent may be used depending on assembly conditions.

ヒント

  • Although oil tolerance is built into LOCTITE 5188, optimal bond and longevity are achieved when surfaces are as clean as reasonably possible.

  • Maintain the gap within specified range and avoid over-application to minimize cured adhesive protrusion.

FAQs (Frequently Asked Questions)

Q1: Can LOCTITE 5188 be used on aluminum flanges?
A1: Yes—it is formulated for use on aluminum and steel, with excellent adhesion to passive substrates.
Q2: What if the flange surfaces have a little oil or lubricant residue?
A2: LOCTITE 5188 is designed to tolerate minor oil contamination, reducing the need for full degreasing.
Q3: What is the maximum gap it can fill?
A3: Approximately 0.25 mm unprimed according to the manufacturer.
Q4: What temperature range does it support?
A4: It supports service from –55 °C up to +150 °C (–65 °F to +300 °F).
Q5: Is it suitable for disassembly?
A5: Yes, though it forms a durable seal—disassembly should follow guidelines for heat or mechanical separation as required.
