How should TC's (Thermal Coatings) be positioned around a repair?

The appropriate positioning of Thermal Coatings (TCs) around a repair involves maintaining an equal distance or spacing around the repair area. This approach ensures that the thermal protection is uniformly distributed, which is crucial for effective thermal management and structural integrity. Uniform spacing helps avoid areas of weakness or thermal stress concentrations, which can occur if the coatings are unevenly distributed.

Additionally, equally spaced coatings enhance the overall effectiveness of the thermal barrier, providing consistent protection against heat and ensuring that there are no points that could experience higher thermal loads due to uneven application. This method supports the intended performance of the coatings and contributes to the durability and longevity of both the repair and the surrounding structure.
