What is the recommended angle when applying sealant to avoid bonding issues?

The recommended angle when applying sealant to avoid bonding issues is low. This approach helps ensure that the sealant can flow and adhere properly to the surfaces it is being applied to, minimizing the risk of trapping air or creating inconsistencies in the seal. By applying the sealant at a low angle, you further facilitate the proper wetting of the surfaces, leading to a stronger and more effective bond.

Using a low angle allows for better control of the material and assists in achieving the desired thickness and coverage, which are critical factors in effective sealing. A proper application technique is essential in maintaining the structural integrity and functionality of low observable aircraft, where sealants play a key role in preserving aerodynamic properties and reducing radar signatures.
