What is the standard open time for urethane application?

The standard open time for urethane application is set at 8 minutes. This timeframe is crucial for ensuring that the urethane adhesive can be effectively applied and that subsequent components can be properly positioned before the adhesive begins to cure. Open time refers to the period during which the adhesive can still be manipulated and bonded to another surface without losing its adhesive properties.

Understanding the significance of this timeframe is important for achieving a successful installation. If the urethane is allowed to sit for too long past its open time, it may start to cure, making it difficult or impossible to achieve a proper bond. Therefore, knowing that 8 minutes is the recommended duration helps technicians manage their workflow efficiently during the application process.
