Epoxy 151 UW Fast
Epoxy 151 UW Fast is an accelerated version of the proven Epoxy 151 UW underwater-curable epoxy system, specifically formulated for projects requiring rapid handling, fast curing, and minimal downtime. This solvent-free, 100% solids epoxy coating cures in the presence of water and remains unaffected by humidity or surface moisture, making it ideal for emergency repairs, maintenance shutdowns, potable water infrastructure, and submerged assets. The coating provides outstanding long-term corrosion protection, excellent impact resistance, and certified drinking water compliance.
Available in 1L kits, 200ml repair squish packs, and 0.45L & 0.9L cartridge systems.
