921 REFLEX ELASTOMERIC ROOF COATING is highly reflective, and formulated to provide a tough, durable roof while adhering to most roofing substrates. The reflective finish will keep the sun’s damaging rays from prematurely aging the roof, while keeping the substrate temperatures substantially lower to alleviate stress on the membrane. The significant degree of flexibility gives 921 REFLEX ELASTOMERIC ROOF COATING the ability to expand and contract with the movement on the roof.
