True or False: Injection sealing is used when a continuous bead of sealant cannot be applied effectively.

Injection sealing is indeed a method used when a continuous bead of sealant cannot be effectively applied. This technique involves injecting sealant into specific areas or joints where a traditional bead application would be difficult or impossible due to space constraints, joint configurations, or access issues.

This method allows for a precise application of sealant, ensuring that the areas that need sealing are adequately treated without the requirement for a continuous line of sealant. This can be particularly useful in complex geometries or assembly situations where maintaining a clean and effective sealing surface is critical, especially in aerospace applications where the integrity of seals is paramount for safety and performance.

Using injection sealing not only improves the effectiveness of the sealing process but also helps to minimize waste and allows for a more controlled application, which is essential in maintaining the quality standards required in aerospace manufacturing and maintenance.
