Sugru is the incredible new self-setting rubber for fixing and improving your gadgets and tools, and making them work better for you.
What does Sugru bond to?
Sugru bonds really well to wood, glass, fabric, ceramics, leather and most metals – including aluminium, steel, iron, and enameled, powder coated, lacquered, and spray-coated metals. It also bonds to most rubbers and plastics like ABS and Polycarbonate.
What materials does Sugru not stick to?
Sugru and most other adhesives struggle to bond with Polypropylene, Polyethylene, and metals with certain oily finishes.
If you want to use Sugru as an impression / molding material, the best release agent is soapy water. It doesn’t leave any oily residue on the Sugru afterwards, and is very clean and easy to use.
Is Sugru removable?
Sugru can be removed from non-porous surfaces.
To remove Sugru, simply cut off the bulk of it off using a knife or scalpel. You can then remove the residue with your nails and some tissue. Here’s a video showing how
If you stick Sugru to a porous unglazed ceramic surface, or unvarnished wood, it will be removable but will leave a stain.
Once you’ve worked Sugru into fabric or leather it will be very difficult to remove, and will always leave traces.
How long is it workable?
Once a package is opened it is workable for about 30 minutes depending on temperature. Putting Sugru in the fridge extends the workable period up to an hour. It takes 24 hours to fully cure at room temperature.
Can I paint Sugru?
As Sugru is a silicone and cures to a flexible rubber, it’s likely that paint will flake off. You can, however, mix and blend different colours of Sugru together to get the shade you need.
Can I mould Sugru ?
Yes, Sugru can take perfect impressions of textures and be used to mould parts. Simply rub a fine layer of soapy water onto the surface you don't want Sugru to bond to.
Can Sugru be used in contact with food or drink?
Sugru is fine to use for handles and the outside of kitchen equipment, but not in direct contact with food or drink.
