To achieve a level and deep glossy finish, __________ is added to slow dry time.

To achieve a level and deep glossy finish, a retarder is added to slow the drying time of the finish. When a finish dries too quickly, it can lead to surface irregularities such as brush strokes, uneven gloss, and an insufficient level of flow-out, which can impact the overall appearance. By incorporating a retarder, the drying process is elongated, allowing for better leveling and smoothing of the surface, ultimately resulting in a more uniform and glossy finish.

The use of a retarder is particularly beneficial in various painting and finishing applications, as it helps to optimize the finish quality. It gives the paint or coating time to settle and minimizes the risk of defects that can occur when the material dries too rapidly. This strategy is essential for achieving professional-grade results in aircraft fabric covering, where appearance and finish quality are paramount.
