METALCLAD® SpeedAlloy is a quick-curing, 100% solids, polymeric ‘leak stopper’ used for making fast, effective repairs to equipment which must be returned to service almost immediately. It has a paste consistency when first mixed and then transforms into a metal-hard composite in just minutes for a long-term leak-stopping solution.

METALCLAD® SpeedAlloy QS is the fastest-curing leak stopper for situations that allow little to zero downtime. SpeedAlloy QS is the first step to stopping an active leak. Then apply SpeedAlloy or METALCLAD® DurAlloy to easily provide a long-term solution.

More Info


SpeedAlloy is a 100% solids, two-component system for quickly curing leaks with minimal downtime. It is applied as a paste and forms a metal-hard protective seal within minutes of applying.ENECON®’s unique and convenient A-Packs and the 1:1 component ratio allow for the easiest and most precise mixing and application of the SpeedAlloy system to ensure minimal downtime.


SpeedAlloy QS has an extremely fast initial set time, making it the ideal material for stopping the flow and effectively plugging almost any active leak.The SpeedAlloy features unlimited shelf life and protection against a broad range of chemical attack, further increasing longevity of the most important equipment, machinery, and piping in the most demanding industrial environments.
