What is the difference between primer and activator?
Primer or activator : what’s the difference? When using a SUPER GLUE Colle21, two complementary products often come up : the primer and the activator.
They can both improve the result of a collage, but they do not have the same function.
The difference is simple : the primer prepares a difficult surface to promote adhesion of the cyanoacrylate glue, while the activator accelerates the setting and hardening of the SUPER GLUE Colle21.
Understanding this difference allows you to choose the right product, avoid certain bonding failures and obtain a faster, more precise and efficient result.
Primer or activator : the quick response
Are you hesitating between the two? Just remember this:
- Primer = prepare certain surfaces that are difficult to bond.
- Activator = accelerate the setting of SUPER GLUE Colle21.
The primer therefore mainly acts on the support before gluing, while the activator acts on the polymerization speed of cyanoacrylate glue.
Depending on the application, these two products can also be complementary.
What is Primer21 used for ?
The PRIMER21 Colle21 30ml is specially designed to improve the adhesion of the SUPER GLUE Colle21 on certain plastics known to be difficult to stick.
This is particularly the case for materials such as :
- polypropylene PP ;
- polyethylene PE ;
- the PTFE ;
- certain technical plastics with poor adhesion.
On these materials, a cyanoacrylate glue used alone can sometimes have difficulty adhering correctly.
The role of the primer is therefore to prepare the surface before applying SUPER GLUE Colle21.
It is not used to make the glue dry faster.
When to use Primer21 Colle21 ?
The Primer21 Colle21 can be particularly useful for :
- certain plastic repairs;
- model making;
- DIY;
- PP or PE parts;
- certain technical applications;
- assemblies on materials traditionally difficult to glue.
Before application, surfaces must be clean, dry and degreased.
The primer is applied to the area to be bonded then left to dry before using the SUPER GLUE Colle21.

What is an activator used for ?
The activator meets a completely different need.
Its role is to accelerate the polymerization of cyanoacrylate glue, in order to obtain a much faster setting.
With a SUPER GLUE Colle21, the activator can be particularly useful when it is difficult to hold two elements in position for several seconds or when very rapid bonding is desired.
It is particularly appreciated in:
- model making;
- model making;
- DIY ;
- precision work;
- assembly of small parts;
- repair ;
- repetitive assembly.
Activator Spray Colle21 200ml
The Activator Spray Colle21 200ml allows for practical and rapid application on large surfaces.
It is particularly interesting when you want to accelerate the setting of the SUPER GLUE Colle21 on a work area or during assemblies requiring immediate fixing.
The spray format is practical for model making, DIY, repair work or even repetitive use.
Liquid Activator Colle21 with brush
For more localized applications, the Liquid Activator Colle21 with brush applicator offers more precision.
The brush allows you to deposit the product exactly where it is needed.
This solution is particularly suitable for :
- small parts;
- precise assemblies;
- model making work;
- careful repairs;
- difficult to access areas.
Primer or activator : which to choose ?
The choice simply depends on the problem encountered.
If your SUPER GLUE Colle21 adheres with difficulty to PP, PE, PTFE or certain technical plastics, the preferred product is the Primer21 Colle21.
If, on the contrary, your objective is to reduce the setting time of your cyanoacrylate glue, choose one Activator Colle21.
For quick application over a larger area, the Activator Spray Colle21 is particularly practical.
For a more precise and localized application, the Liquid Activator Colle21 with brush will often be more suitable.
The Primer21 Colle21 and the Activator Colle21 therefore do not fulfill the same function : they are complementary in a complete bonding solution.
Can we use the primer and activator together?
Yes, when the type of bonding requires it.
Let’s take the example of an assembly made on a difficult plastic.
The Primer21 Colle21 can be used first to prepare the surface.
After drying, the SUPER GLUE Colle21 is applied.
If the assembly then requires a particularly rapid setting, a Activator Colle21 can be used in addition.
The principle is therefore simple:
Primer21 Colle21 → surface preparation → SUPER GLUE Colle21 → Activator Colle21 to speed up setting.
Why choose SUPER GLUE complementary products Colle21 ?
The success of a bond does not only depend on the power of a glue.
It is also necessary to take into account :
- the nature of the material;
- the condition of the surface;
- the viscosity of the glue;
- the quantity of product used;
- the precision sought;
- the necessary setting time;
- the flexibility or rigidity of the assembly.
This is why SUPER GLUE Colle21 offers a wide range of cyanoacrylate glues and bonding products designed to meet different needs.
Liquid glue, FAST, DENSE, GEL, flexible glues, primers, spray activators, liquid activators and precision accessories: the objective is to be able to choose the right solution for each application.
This diversity also allows SUPER GLUE Colle21 to offer excellent value for money for both individuals and professionals.

FAQ – Primer or activator for SUPER GLUE Colle21 ?
What is the difference between a primer and an activator?
The primer prepares certain difficult surfaces to improve glue adhesion, while theactivator accelerates the polymerization and setting of SUPER GLUE Colle21.
Does the activator make PP or PE stick better?
This is not its main function.
For PP, PE or PTFE, it is preferable to use the Primer21 Colle21 to prepare the surface before bonding.
Which SUPER GLUE activator Colle21 choose?
You can choose the Activator Spray Colle21 for quick and practical application.
For a more localized application, choose Liquid Activator Colle21 with brush.
Does Primer21 dry SUPER GLUE Colle21 faster?
No.
The Primer21 Colle21 serves to prepare some difficult surfaces.
To speed up the setting of a SUPER GLUE Colle21, you must use an activator.
Can we use SUPER GLUE Colle21 without activator?
Yes.
The activator is a complementary product used when you want to obtain a particularly rapid setting.
Primer or activator : the essential things to remember
The Primer21 Colle21 and the Activator Colle21 meet two different but complementary needs.
If the problem comes from material and its adhesion, especially on certain difficult plastics, use the primer.
If, on the contrary, you wish speed up the setting of your SUPER GLUE Colle21, use a spray or liquid activator.
With SUPER GLUE Colle21, the objective is to offer a complete bonding solution, adapted to the material, the type of work, the desired precision and the desired setting time.
