Sylmasta AB Original Pipe Repair Epoxy Putty
Sylmasta AB Original is a ceramic-filled epoxy putty with a slow work time, enabling bulk quantities to be mixed and applied in complex pipe repair and surface restoration applications.
It seals holes and cracks in pipes made of steel, iron, copper, PVC plastic, GRP, ceramic, concrete, lead, and rubber. Where the exterior of a pipe has been damaged by corrosion, it strengthens and restores the surface profile to improve pipeline integrity and offers an ultra smooth finish.
AB Original makes underwater repairs, offers excellent adhesion to wet surfaces, and has high chemical resistance. In chemically aggressive environments, it works as a sacrificial layer to protect pipework.
Sylmasta AB Original is available in bulk sizes up to 50kg for large-scale applications. It is available in white, black or grey as standard to match pipework. Further colour customisation is possible; please contact Sylmasta for more information.
AB Original has a two hour work time. This allows more putty to be mixed in one go without the threat of premature curing, minimising waste, and allowing significant areas of damage to be repaired. Sylmasta recommend AB Original to clients operating in hot climates because of its cure time.
For a faster curing version of AB Original, please see Sylmasta AB Rapid 5 Minute. AB Rapid can be purchased in large quantities like AB Original, but comes with a quick work time similar to a Superfast Epoxy Putty Stick, allowing it to make rapid repairs.
Sylmasta AB Original contains no solvents or VOC’s, is non-flammable and releases no noxious fumes. It will not shrink or pull away when setting. The unused portion stays fresh for future use when saved in its original package.
How to repair damage and seal leaks on a pipe with Sylmasta AB Original Epoxy Putty
Sylmasta AB Original comes in two parts and is applied by hand. Part A and Part B are mixed together in even quantities by weight or volume until thoroughly mixed.
Whilst soft, AB Original is pushed into holes and cracks in pipework, where it will harden to seal leaks. For repairing surfaces, the putty is smoothed over areas of damage, curing to restore pipeline integrity.
Sylmasta AB Original has a work time of 1.5 – 2 hours. A full cure is achieved in 24 hours. Once cured, the Epoxy Putty can be tapped, drilled, screwed, sawed, machined, ground, filed, or painted, to create a seamless finish uniform with the pipe undergoing repair. It will not rust.
To reinforce repairs made with AB Original, Sylmasta recommend overwrapping the Epoxy Putty with a SylWrap HD Pipe Repair Bandage. The Bandage offers a rock hard, impact resistant layer of protection.
