BSI Mid-Cure 15-Minute Epoxy – 4.5 oz BSI203

The BSI Mid-Cure 15-Minute Epoxy (BSI203) is a two-part epoxy with a 15-minute working time — ideal for complex assemblies that require more time to position and align parts before the adhesive sets. The longer working time also results in a stronger, tougher final bond compared to 5-minute epoxy, making Mid-Cure the preferred choice for structural RC aircraft joints, wing saddles, and other high-stress applications. Full cure in 3–4 hours.
