What to choose between Super Glue or epoxy? It all depends on the type of repair, the materials to be assembled, the space between the parts and the desired resistance.
These two glues can make very strong joints, but they do not work in the same way.
The SUPER GLUE Colle21 cyanoacrylate is ideal when you are looking for speed, precision and ease of use.
The two-component epoxy glue Colle21 is generally more suitable when it is necessary fill a space, reposition parts or carry out an assembly subject to more mechanical constraints.
When to choose a SUPER GLUE Colle21 ?
Super Glue or epoxy: which to choose? A Super Glue is a fast-setting cyanoacrylate glue.
It is particularly interesting when the two surfaces are well adjusted and you want to complete the bonding quickly.
Choose a SUPER GLUE Colle21 for :
- small repairs;
- model making;
- well-fitted pieces;
- small areas;
- assemblies requiring a lot of precision;
- repairs where rapid setting is important.
For example, SUPER GLUE Colle21 DENSE has a high viscosity allowing better control of application and limiting dripping.

Cyanoacrylate is therefore particularly effective when we want to stick quickly and precisely with very little product.
When to choose an epoxy glue?
Super Glue or epoxy : which to choose ? An epoxy glue works differently.
It is composed of two components : a resin and a hardener. Mixing them triggers a chemical reaction that allows the adhesive to harden.
Epoxy is particularly interesting when :
- surfaces do not fit perfectly;
- there is a space to fill;
- the bonding area is large;
- the part undergoes vibrations or mechanical stress;
- you need time to reposition the elements;
- you are working on metal, wood, composites or other rigid materials.
The Two-Component Epoxy Glue Colle21 25ml has a syringe allowing the two components to be dosed and its initial setting is expected to take around 5 to 6 minutes.

Super Glue or epoxy : the main differences
Do you need very quick bonding ?
Instead, choose one SUPER GLUE Colle21.
Cyanoacrylate begins to set very quickly and is particularly suitable for small, correctly positioned parts.
Do you need to fill a space?
The epoxy is generally preferable.
A Super Glue works best with a thin bond line, while an epoxy has a better ability to fill irregularities between two parts.
Is the part subject to stress or vibration?
For a structural or heavily stressed assembly, the epoxy is generally more suitable.
Do you need to reposition the parts?
Choose the epoxy.
Its working time is longer and allows more adjustments before setting.
Do you need to repair a small part immediately?
The SUPER GLUE Colle21 will often be more practical thanks to its speed and precision.
Which glue depending on the material?
The material is also decisive.
Metal
Both solutions can work.
For a small precise fixing, a SUPER GLUE Colle21 may be enough.
For a larger assembly or one subject to constraints, choose epoxy instead.
Plastic
It depends on the type of plastic.
Many plastics can be bonded with a cyanoacrylate, but some materials like PP, PE or PTFE require special preparation.
Wood
For a small, precise bond, cyanoacrylate can be interesting.
For a larger or irregular surface, an epoxy may be preferable.
Carbon fiber and composites
For a small fixing, a SUPER GLUE Colle21 can be used.
For a structural repair or an assembly subject to mechanical stress, a two-component epoxy is generally more suitable.
Ceramic
Both technologies may be suitable depending on the size of the break and the fit of the pieces.
Can you use Super Glue and epoxy on the same repair?
Yes, in some specific jobs the two technologies can play different roles.
A cyanoacrylate can for example be used to make a rapid positioning, while an epoxy is used to create the main bonding.
However, this should only be done when the design of the repair allows it.
In the majority of situations, the simplest thing is to choose from the start the glue adapted to the real need.
Mistakes to avoid
Super Glue or epoxy: which to choose? Whether you use Super Glue or epoxy, certain errors can significantly reduce the quality of the bond:
- work on a greasy or dusty surface;
- using too much glue;
- choose a product unsuitable for the material;
- not respecting the mixture of the two components of an epoxy;
- move the pieces during setting;
- request repair before sufficient hardening.
Preparation therefore remains essential :
clean → degrease → choose the right glue → apply correctly → let it set.

FAQ – Super Glue or Epoxy : Which to Choose ?
What is the difference between Super Glue and epoxy ?
The Super Glue is a fast cyanoacrylate glue, particularly suitable for small, well-fitted surfaces. Epoxy is a two-component glue offering more working time and a better ability to fill spaces.
Which glue is the fastest ?
The SUPER GLUE Colle21 is generally much faster than an epoxy.
Which glue to choose for a solid repair ?
It depends on the repair. For a small, tight-fitting part, a cyanoacrylate can create a very strong bond. For a structural part, large surface area, or stressed assembly, epoxy is generally preferable.
What glue should I use if there is material missing between the parts ?
Instead, choose one epoxy glue, which allows more filling than a classic cyanoacrylate.
Which glue to choose for model making ?
Both are useful. A SUPER GLUE Colle21 is ideal for quick and precise assemblies, while an epoxy is interesting for heavier parts or those requiring more resistance.
Super Glue or Epoxy for Metal ?
For a small room, Super Glue may be perfectly suited. For a structural assembly, heavily stressed or with a gap, epoxy will generally be preferable.
Conclusion : Super Glue or epoxy, which one to choose?
There is no universal winner between Super Glue and Epoxy.
The right choice depends on your repair.
Choose a SUPER GLUE Colle21 if you are looking for:
speed → precision → small surface → well-fitted parts.
Choose an epoxy Colle21 if you are looking for :
structural strength → infill → large surface area → repositioning time → stressed assembly.
The most important thing is therefore not to choose a glue just because it is “strong”.
You have to choose the technology truly adapted to the material, geometry and constraints of your repair.
