BSI Slow-Cure 30-Minute Epoxy – 4.5 oz BSI205

The BSI Slow-Cure 30-Minute Epoxy (BSI205) is BSI's highest-strength two-part epoxy, with a 30-minute working time for large, complex assemblies that require maximum positioning time. The slow cure produces the toughest, most flexible bond in the BSI epoxy lineup — ideal for fiberglass and carbon fiber lamination, structural RC aircraft joints, and any application where maximum strength and impact resistance are required. Full cure in 8–12 hours.
