REBUILDS EQUIPMENT DAMAGED BY CAVITATION.
SUPERIOR STRENGTH, DURABILITY AND ADHESION WITH FLEXIBILITY, ABRASION RESISTANCE AND ELONGATION.
FLEXICLAD DuraTough DP is a two component, 100% solids elasto-ceramic polymer composite specifically formulated to rebuild equipment prone to cavitation attack and subsequent damage.
DuraTough combines the superior strength, durability and adhesion of an epoxy with the exceptional flexibility, abrasion resistance and shock-absorbency of an elastomeric urethane.
FLEXICLAD DuraTough DP is ideal for rebuilding cavitated areas as well as creating or rebuilding flexible seals, gaskets, seats, etc, on machinery and equipment such as heat exchangers, pumps, valves and piping systems.
