It is important to keep in mind that black rubber toughened CA glues have an extended bonding time due to the added rubber compound and the higher the viscosity (CPS) the longer the bonding time is. It can take as much as 24 hours to fully cure when larger volumes of the adhesive is applied. For these instances, use of accelerator is highly recommended.
If you’re considering CA glue without an accelerator, you might wonder if an accelerator is necessary. Several factors can help you decide. Warmer temperatures speed up curing, while colder temperatures slow it down. The ideal working temperature for CA glues is around 75°F – 80°F, so if your workspace is cooler, using an accelerator can ensure proper curing. Surface energy also plays a role: denser, nonporous surfaces require more time for adhesion, but abrading the surface with sandpaper or a file can improve bonding. In such cases, an accelerator speeds up the initial bond. Wood and metal generally have high surface energy, while plastics and rubber have low surface energy. Additionally, medium-thick and thick CA glues take longer to cure, which can be inconvenient. Applying these glues in multiple thin layers and using an accelerator can hasten the process, especially for rubberized variants like Black CA glue. Ultimately, the choice to use an accelerator with CA glue depends on your personal experience and needs. Some people are satisfied with the natural curing time, while others prefer the added control and faster results that an accelerator provides.
