Effects from an off-ratio burst can be prevented by what?

Preventing effects from an off-ratio burst is crucial in composite applications, particularly to ensure the integrity and performance of the final product. Spraying the perimeter of the flange first helps create a controlled application, which can minimize the risk of an off-ratio condition. By addressing the areas at the edges or boundaries first, the operator can manage the flow and curing of the materials more effectively, ensuring that the core structure receives the appropriate mix of resin and hardener.

This technique allows for better observation and adjustment during the initial application process, should any discrepancies in the ratio occur. Starting with the perimeter establishes a defined area that can be monitored closely for uniformity and proper mix, which ultimately leads to a more consistent and safe composite structure. In contrast, merely changing equipment, adjusting pressure settings, or altering materials might not address the core issue of ratio consistency during the critical application phase.
