EC4000 Thick Black Rubber Toughened CA Glue

EC4000 Thick Black Rubber Toughened CA Glue handles applications requiring extreme flexibility, shock resistance, vibration resistance, and toughness. In addition, it delivers a more flexible bond than standard cyanoacrylates, making it ideal for loudspeaker repair and assembly.

How It Works

EC4000 Thick Black Rubber formula polymerizes instantly by absorbing surface moisture. As a result, it delivers fast curing qualities that make it especially desirable in high speed industrial production environments. Moreover, we have tested its performance across a wide variety of materials and applications beyond speaker building.

Features

• Shock and impact resistant
• Humidity resistant
• Good gap-filling capabilities
• 4000 cps viscosity
• Fast curing
• Bonds to plastics, rubbers, metals, composites, wood, and ceramics

EC4000 CA glue works well for the following loudspeaker applications:

• Voice coil to spider
• Triple joint ring to voice coil
• Spider to frame
• Spider spacer to frame
• Cone to voice coil
• Foam surround to frame

Curing Time

Black rubber toughened CA glues have an extended bonding time due to the added rubber compound. In some cases, it can take up to 24 hours to fully cure when you apply larger volumes of adhesive. Therefore, we highly recommend purchasing our AC1101 CA Glue Accelerator separately for time-sensitive applications.

Storage and Handling

For optimum shelf life, store at 40°F or below both before and after use. In addition, when well kept in a cold environment, this product enjoys an extended shelf life.

Notes

EC4000 works as a one-component, rapid-bonding adhesive that polymerizes instantly by absorbing surface moisture. Moreover, professionals widely use this formula in the aerospace, automotive, and electronic industries. Therefore, for gluing dust caps, we recommend using our black rubber speaker repair glue instead.

Need an Accelerator Too?

We also offer the EC4000 as a kit with the AC1101 CA Glue Accelerator included. In addition, buying the kit saves you from ordering the accelerator separately.
