Superfast Copper Epoxy Putty Stick
Superfast Copper is a fast-working epoxy putty in a 114g stick used to seal holes, cracks and leaking joints in domestic copper pipes and smaller industrial applications where pressure is off.
It is copper-filled and specially formulated for use on copper and other non-ferrous metals including brass or bronze. It is suitable for both domestic and industrial repairs, temperature resistant to 150°C and pressure resistant to 30 bar.
Superfast Copper also rebuilds small areas of damage, restoring pipeline integrity by increasing the thickness of sections weakened by corrosion and other forms of attack. It can reprofile pipes by filling pitting and smoothing out difficult shapes, like edges and steps.
It has WRAS approval, meaning it is certified to British standards as safe to use on pipes carrying drinking water. Pipework can go back into full service within one hour of repair using Superfast Copper.
Superfast Copper is resistant to water, chemicals and does not rust. It contains no solvents or VOC’s, is non-flammable and releases no noxious fumes. It will not shrink or pull away. Any unused putty stays fresh for future use when saved in its original packaging.
Cured Superfast Copper can be tapped, drilled, screwed, sawed, machined, ground, filed or painted to create a seamless finish uniform with the pipe undergoing repair.
Unlike most other suppliers of pipe repair products, Sylmasta make all their own epoxy putty sticks using the latest manufacturing technology at their production plant in the United Kingdom. This guarantees fresh product, a reliable supply chain and reduced lead times.
How to fix a leaking pipe using Superfast Copper Epoxy Putty Stick
Superfast Copper Epoxy Putty Stick comes pre-measured with the correct 1:1 ratio of resin to hardener. The user simply cuts the required amount of putty from the stick and kneads by hand.
The two contrasting colours blend into a uniform copper to indicate successful mixing. Whilst Superfast Copper Epoxy Putty is still soft, the user then pushes it into the crack or hole in the metal pipework.
Superfast Copper has a work life of approximately 3 minutes. It hardens within 5-10 minutes to form a solid, watertight material sealing the hole. It achieves working strength in one hour and a full cure with maximum properties in 24 hours.
When pipe reprofiling or rebuilding damage by increasing the outer wall thickness of weakened sections, the user presses Superfast Copper firmly onto the area requiring improvement. It cures to create a flat, smooth surface.
Reinforcement with SylWrap HD Pipe Repair Bandage
Sylmasta recommend reinforcing pipe repairs made with Superfast Copper by overwrapping the epoxy putty with a SylWrap HD Pipe Repair Bandage.
SylWrap HD is a water-activated composite wrap. It sets rock-hard in minutes to form an impact resistant layer of protection covering Superfast Copper for a permanent repair.
Slower setting and high temperature epoxy putty for pipe repair
For complex pipe repair applications requiring longer than 5 minutes to mix and apply epoxy putty, please see Sylmasta AB Original Epoxy Putty.
AB Original comes with a two-hour work time. The extended cure means the user does not need to rush mixing or application through worry about the putty curing off too quickly.
For higher temperature repairs in excess of the 150°C resistance of Superfast Copper, please see Superfast Titanium Epoxy Putty Stick. Superfast Titanium offers resistance to up to 280°C.
