Crackbond LR321 is a low viscosity, high modulus structural epoxy adhesive used for a variety of repair projects. With its low viscosity, it is perfect for gravity-feed horizontal cracks and can be used in temperatures between 40F and 100°F (5°C and 38°C). It can be used as a vertical crack repair using injection ports in conjunction with a capping gel. Its bonding and sealing capabilities for interior/exterior slabs are exceptional for use as an epoxy mortar spall repair when mixed with aggregate.
