We provide all the relevant safety information for our products in the most useful places – where you will look for it. Mostly you’ll find it on the back of each pack and in accompanying leaflets and booklets. You’ll also find it here on our website: either on general information pages or on individual how-to pages for specific fixes and projects.
The purpose of this page is to compile the most important parts of that safety information for those of you who may have specific concerns and want to find it all in one easy place.
Q: Is Sugru Mouldable Glue skin-safe?
A: There are two formulas of Sugru Mouldable Glue: Family-safe | Skin-friendly Formula and Original Formula. If you bought your Sugru from September 2017 onwards, the formula inside is clearly marked on each package. If you bought your Sugru before this date, it’s the Original Formula.
Our new Family-safe | Skin-friendly Formula of Sugru is made with chemistry that is mild enough for even children to use. Therefore, we recommend this Formula to anyone planning to use Sugru with children, or in applications where there will be prolonged contact with skin either in its uncured or cured form, for example craft projects or repairs to eyeglasses.
Our Original Formula contains very small amounts of sensitising ingredients, so it is possible for it to cause an allergic reaction in a very small number of people with sensitive skin, or after constant, prolonged contact. For this reason, we don’t recommend Sugru is used anywhere it would be in constant contact with the skin, such as dental applications, prosthetics, headphones or eyeglasses, for example. The appropriate warning appears on the back of every single-use pack of Original Formula Sugru.
You can find more information on the SDS (Safety Data Sheet) – we have European, American, Australian and New Zealand versions available.
Q: Can kids use Sugru Mouldable Glue?
A: Kids love Sugru because it's just like play-dough when it comes out of the pack. For any use where you plan to involve children, choose our Family-safe, Skin-friendly Formula. It’s suitable for unsupervised use by kids from age 8+.
As for parents using Sugru around toddlers and small kids, we’ve seen lots of great parenting projects from our community such as making sharp corners safe and fixing toys, but we don’t recommend using Sugru if kids are likely to chew on it, as it could break off and cause a choking hazard. And as it’s not food safe, it shouldn’t be put into the mouth.
Q: Is Sugru Mouldable Glue food safe?
A: Sugru is not classified as toxic, but it’s not food safe either, so it shouldn’t be used in contact with food or drink. Also, please resist the urge to eat it (or feed it to your pets).
Q: I’m allergic to latex – is Sugru Mouldable Glue latex-free?
A: Sugru doesn’t contain latex, but we can’t guarantee that at some point in the manufacturing process an operator wearing latex gloves hasn’t handled it.
Q: Is Sugru electrically insulating?
Yes, as a silicone, Sugru has high insulation properties (please refer to our technical data sheet as needed), however, we recommend that you be very careful with electricity. Always err on the side of caution and stick to small consumer electronics’ repairs below 24 volts, 24 watts or 1 amp.
Q: What are the limits of Sugru for hanging and mounting things on the wall?
A 5g single-use pack of Sugru can hang up to 2kg. Make sure the surfaces you’re working with are not included on the ‘what does Sugru not stick to?’ list. Always ensure the surfaces are clean and dry and that your hands are clean and dry too.
In general, there are three things always recommend in our how-to instructions for hanging and mounting:
It’s always best to maximise the surface area of the contact between the Sugru, the item you’re mounting, and the wall i.e. it’s best to divide into several small pieces evenly spaced than depend on only one point of contact.
Take care while mounting heavy things to painted walls, although the Sugru may be strong enough, sometimes the paint may fail.
Use tape to hold the weight of the object you’re mounting for 24hrs while the Sugru cures
Q: What does Sugru Mouldable Glue not stick to?
Like most adhesives, Sugru struggles to bond to plastics with certain oily finishes such as polypropylene, polyethylene and Teflon™, some powder-coated metals, and chalky or dusty surfaces. For best results with all other materials, ensure the surfaces are clean and dry.
Q: Is there anything else I should know to stay safe while using Sugru Mouldable Glue?
Use your common sense. Millions of people around the world are using Sugru successfully and safely. As a community, we’ve now fixed more than 14 million things. However, as with any material or adhesive, sometimes people do silly things with it. The uses you may see on the Internet are not all recommended as conditions of use, and are beyond our control.
Use your own judgement as to whether Sugru is the right solution for your specific fix or project, or if you’d prefer, just get in touch with us to check at [email protected]
Have fun and stay safe!
