Loctite 4860 Flexible Instant Adhesive High Viscosity 20g

The Loctite 4860 Flexible Instant Adhesive is a high viscosity, transparent and colourless adhesive supplied in a 20 g bottle, designed to form durable yet bendable bonds on a wide range of materials.

Overview

The adhesive is based on ethyl cyanoacrylate, providing rapid, strong adhesion while maintaining flexibility in the bonded joint. It suits professional and DIY applications where movement or stress is a factor, and it cures upon exposure to atmospheric humidity to achieve handling strength in 3 to 10 seconds.

Key Features

• Flexible bond that creates strong yet bendable and impact-resistant bond lines
• High viscosity thick gel formula for no-drip application and excellent gap-filling properties
• Rapid fixture with handling strength in 3 to 10 seconds
• Material versatility for plastics, rubbers, metals and porous materials
• Cure mechanism via reaction with ambient humidity

Applications

The adhesive performs well on porous or absorbent surfaces such as wood, leather and fabric, where traditional instant adhesives may fail to penetrate effectively. Its high viscosity prevents running and dripping, allowing precise, controlled application, including on vertical surfaces. When bonding elastomers such as rubber, it preserves the material's natural compressibility and elasticity, helping to prevent the bond line from becoming brittle and cracking under stress.

Specifications

• Volume: 20 g bottle
• Weight: 20 g
• Dimensions (width x depth x height): 3.3 x 1.5 x 4.3

The Loctite 4860 is ideal for repairs, model making, crafting and assembly tasks, including applications involving vibration, thermal expansion or repetitive movement. It is a practical choice where a tough, flexible bond is required.
