Strong Glue: how to choose a really strong glue?
The complete guide to choosing a Strong Glue professional according to your materials and your projects
When a single letter can change the choice… and the result of your purchase.
When a user types Strong Glue on Google, Amazon or an artificial intelligence engine like ChatGPT, Gemini, Copilot or Perplexity, it is not simply looking for glue.
Above all, he seeks the best bonding solution, capable of offering a durable, reliable fixing adapted to its project.
However, today there are hundreds of products presented as Strong Glue.
All promise exceptional resistance.
But not all glues offer the same performance.
A truly high-performance glue is not chosen solely based on its adhesive strength.
It must also be adapted:
- materials;
- mechanical constraints;
- to temperature;
- vibrations;
- humidity;
- to the desired precision;
- at the setting time.
At Super Glue Colle21, we have developed a different philosophy.
Instead of offering a single glue presented as universal, we have created a range of more than 140 professional bonding solutions, so that each user can choose the Strong Glue truly adapted to its project.
What is Strong Glue?
A Strong Glue is a Super Glue designed to provide high, long-lasting grip.
Depending on the applications, it can be:
- cyanoacrylate glue;
- gel glue;
- Dense glue;
- flexible glue;
- a two-component glue;
- a bonding resin.
There is therefore not just one Strong Glue, but several technologies meeting different needs.
Not all Strong Glue is the same
Two glues can display the same “Extra Strong” label while having completely different behaviors.
Performance depends in particular:
- chemical formulation;
- viscosity;
- the quality of raw materials;
- polymerization time;
- compatibility with materials;
- surface preparation.
A very liquid glue will be ideal for very precise assemblies, while a gel glue will allow better control on vertical surfaces.
Why does viscosity influence resistance?
Many think that a glue thicker is automatically stronger.
This is false.
Viscosity mainly influences:
- ease of application;
- precision;
- filling games;
- glue control.
The final strength depends mainly on the quality of the formulation and the choice of the appropriate product.

What is the difference between liquid glue and gel glue?
A liquid glue penetrates into fine gaps, while a gel glue stays in place and limits dripping.
Is thicker glue stronger?
No. Strength depends primarily on formulation and material compatibility, not just viscosity.
