TLS-403 sealing adhesive (crack sealing adhesive) is mainly used in conjunction with TLS-402 pouring adhesive steel adhesive and TLS-402F crack repair adhesive to seal pouring gaps, repair concrete surface defects, and level construction. TLS-403T elastic epoxy road and bridge leveling and repair adhesive is an improved version of TLS-403 crack sealing adhesive. It uses a super elastic epoxy curing agent, adds rubber and various inorganic nanomaterials, and is more suitable for repairing non stress cracks in concrete pavements, bridges, dams, subways, and houses. Due to its good thixotropy, it is particularly suitable for repairing facades and roofs.
