Do you need to carry out a quick repair that has to withstand high loads? You do not know exactly which material to use for it? Try Epoxy Putty. In our Epoxy Putty Stick guide, we will tell you what properties this material has, whether Epoxy Putty Stick is heat-resistant and how you can best process Epoxy Putty Sticks.





What is Epoxy Putty Stick?

Epoxy Putty Stick, also called metal plasticine or adhesive metal, is an exceptionally firmly adhering plasticine based on epoxy resin. Epoxy Putty Stick is based on the same two-component system as epoxy. The curing reaction is, therefore, started when the two components resin and hardener are mixed together. However, this system does not require any effort on the part of the user, as the adhesive metal is supplied in a practical roll. Mixing is done solely by kneading the compound.

With this material, minor damage can be permanently repaired. Epoxy Putty Stick does not obtain its reputation for nothing: it can be modeled and is therefore unbelievably flexible; when hardened, it is about as hard as steel. It even sets on damp surfaces or underwater.

The curing process takes only a few minutes for many products. If you have repaired cracks or damaged areas with the help of the metal plasticine, you can further process, paint and sand them. Since Epoxy Putty Stick can be applied to various surfaces, it is suitable for a wide range of work. It offers many advantages not only for industrial processing but also for the do-it-yourselfer.

Advantages and disadvantages of Epoxy Putty Stick




  • Epoxy Putty Stick Hardens quickly
  • Small damages can not only be repaired quickly and effectively, but also permanently
  • It is heat resistant and electrically insulating
  • Very flexible and in principle suitable for almost all repair work
  • Further machining is possible after hardening
  • After the hardening process the Epoxy Putty Stick can be painted and ground
  • Cures without problems even underwater
  • High resistance to chemicals, oils and mechanical stress



  • Epoxy Putty Stick is relatively expensive
  • Care should be taken with floating materials, because a hardening compound can lead to hairline cracks under various environmental influences
  • During processing, you should always pay attention to your safety, as some ingredients are potentially harmful to health – therefore always wear gloves

However, you should not be deterred by the relatively high costs. If you consider that with the help of Epoxy Putty Stick you can also repair expensive components in a stable way, the price of this two-component wrought mass is put into perspective.



Which materials can be bonded with adhesive metal?

As the hardening process of the cold metal is based on the two-component principle, it can be used to bond all conceivable materials together. Not only plastics, glass, glass fiber, ceramics, and wood, but also concrete, steel, and metal can be permanently bonded together with the help of Epoxy Putty Stick.



Processing of cold metal – Instructions

If the Epoxy Putty Stick is supplied in a roll, use a sharp blade, such as a carpet knife, to separate the desired amount from it. You will now see that the outer edge of the roll is grey, while the inside is black – these are the two components that need to be joined together to start a reaction.

  • The first step is to knead the dough thoroughly with your fingers. Do this until the color of the mixture is entirely uniform, and no more streaks appear. In this way, both components of the 2K modeling clay – resin and hardener – are bonded together. When this has been done thoroughly enough, you can feel the material heating up between your fingers.
  • Now apply the plasticine to the surface you want to work on. Press it firmly enough to ensure proper adhesion. Please note that you only have a limited open time after kneading the material. This describes the time in which the material remains malleable. Once the material has hardened, it can no longer be deformed and therefore, can no longer be used as a kneading material. The open time is often only a few minutes.
  • If you want to achieve the smoothest possible surface structure, you can smooth the cold metal with wet hands or a damp cloth.
  • After application, the cold metal usually hardens within an hour. Afterward, it can be worked on as desired.
  • Remains of the Epoxy Putty Stick that you want to store should be immediately packed airtight and stored in a cool and dry place.

What to look for when buying an Epoxy Putty Stick

  • Since it is, of course, not possible to test the cold metal on-site without opening the packaging, you should pay attention to the date on which the cold metal was packed. If this is too long ago, the Epoxy Putty Stick may be too old. Then, in rare cases, it can crumble after hardening if it is processed further. This process is possible and very annoying, especially when machining or producing a thread.
  • Also, pay attention to the open time in which the Epoxy Putty Stick can be processed. Especially if you want to repair more substantial damages with it, it is advantageous to choose a higher open time so that you have more time for the work.
  • You should also pay attention to the heat resistance. In our last section, we will continue with this topic.



Safety Instructions for Processing Metal Putty

Various ingredients of the metal clay can cause not only allergic reactions, but also skin, eye, and mucous membrane irritations. You should, therefore, always keep your safety in mind when working with this material.
