A two-component, 100% solids, high modulus, ultra low viscosity structural epoxy adhesive. Formulated for use as an injection or penetrating resin system for very fine to fine cracks (1/8″ to 1/4″ width) in concrete structures. Useable temperature ranges of 50 to 100 Deg. F. Cures to a solid with no shrinkage, and bonds to both surfaces of the crack, welding the structure back to its original monolithic strength. Characteristics: – Low odor for indoor applications – Self-leveling – Low viscosity (500 cps LR-321 & 200 cps LR-321LPL) – Low surface tension allows for deep penetration into cracks – Available in plural component cartridges or bulk packaging – Moisture insensitive for use in a damp enviroments
