BSI SLOW-CURE™ 30 Minute Epoxy is the strongest and most durable epoxy in the BSI range, engineered for applications where maximum bond strength, waterproofing and heat resistance are essential. With a 30-minute working time, it provides ample time for precise alignment, reinforcing fillets and complex structural assemblies.

This slow-setting epoxy offers excellent surface penetration, resulting in superior bonding on high-stress joints. Once cured, SLOW-CURE™ is fully waterproof and highly resistant to heat and stress, making it ideal for demanding RC models, woodworking, composite construction and general repairs, both indoors and outdoors.
