Keo kết cấu

High-Strength Structural Bonding Solutions for Demanding Applications

Achieve weld-like strength, lightweight designs, and lasting durability with LOCTITE Structural Adhesives.
Engineered for load-bearing assemblies, LOCTITE adhesives bond metals, composites, and plastics with exceptional strength and reliability—ideal for automotive, aerospace, electronics, and industrial manufacturing.

What Is a Structural Adhesive?

A Keo kết cấu is designed to form load-carrying joints that replace or reinforce mechanical fasteners and welds. Unlike ordinary glues, structural adhesives distribute stress evenly across bonded surfaces, improving strength, fatigue resistance, and long-term performance.

Structural adhesives are used wherever components must withstand vibration, impact, and harsh environmental conditions. They help manufacturers reduce weight, minimize machining, và enhance design flexibility without compromising strength.

LOCTITE Structural Adhesive Technologies

LOCTITE offers a complete portfolio of advanced chemistries to meet diverse engineering needs:

• Epoxy Adhesives – Maximum structural strength, high temperature and chemical resistance

• Acrylic / Methacrylate Adhesives – Fast cure, impact-resistant, excellent on metals and plastics

• Hybrid Adhesives – Combine the strength of epoxy with the speed of cyanoacrylate

• Toughened Systems – Improved flexibility and peel resistance for dynamic loads

• Non-Sag Formulas – Ideal for vertical or overhead applications

Each formulation is optimized for specific substrates, cure speeds, and operating conditions—delivering proven performance in industrial assembly lines worldwide.

Why Choose LOCTITE Structural Adhesives?

• Stronger Than Mechanical Fasteners — Replace rivets, bolts, and welds in many designs

• Bond Dissimilar Materials — Metals, composites, plastics, glass, and rubber

• Excellent Environmental Resistance — Withstand vibration, moisture, and chemicals

• Reduce Weight and Complexity — Eliminate fasteners, drilling, and surface distortion

• Faster Production — Controlled cure times and automated dispensing options

LOCTITE structural adhesives enable engineers to design smarter, lighter, and more durable assemblies across industries.

How to Select the Right Structural Adhesive?

When choosing the best LOCTITE adhesive for your application, consider:

1. Substrate type – metal, plastic, composite, glass

2. Stress type – shear, peel, torsion, impact

3. Gap size and joint design

4. Curing time and process conditions

5. Operating temperature and environmental exposure

6. Service life and reworkability

Bonding Process & Best Practices

1. Chuẩn bị bề mặt – Clean and degrease surfaces; abrade if necessary.

2. Mixing & Dispensing – Follow recommended mix ratios; use dual-cartridge systems where applicable.

3. Ứng dụng keo dán – Apply a continuous bead; avoid trapped air.

4. Lắp ráp – Align and clamp components until initial cure.

5. Quá trình làm khô – Allow full cure per product TDS (ambient or heat cure).
