It is important to keep in mind that most black rubber toughened cyanoacrylate glues have an extended bonding time due to the added rubber compound. Larger volumes of the adhesive may require up to 24 hours to fully cure. Â For these instances, use of accelerator is highly recommended.
When well kept, our product can last a longer shelf life when stored in a cold environment. Just make sure to store the bottle under 40°F before and after use.
Notes: EC905 cyanoacrylate adhesive offers a one component rapid bonding adhesive designed to polymerize instantly by absorbing surface moisture. Black rubber is ideal for use in applications that require an easily handled high viscosity adhesive.Â
For gluing dust caps we recommend using our black rubber speaker repair glue.
