HighLine 510H was born out of the success of its predecessor, HighLine 510; it’s one of ArmorThane’s highest quality formulations yet, composed of pure polyurea like HighLine 510, but engineered to exceed its performance. Specifically, HighLine 510H was designed as a tougher, industrial variant with greater durability and hardness, equipped to address highly demanding applications like protecting power plant infrastructure, supporting mining operations, and reinforcing structural steel. Being made for these industrial applications, HighLine 510H is most compatible with pre-treated concrete and metal surfaces and is spray applied using the ArmorThane HighLine plural component spray system.
