🌡️ glue and climate: how humidity and temperature influence cyanoacrylate grip
Have you noticed that sometimes your glue fits perfectly ... and sometimes not at all?
🧩 It's not (only) glue, it's also the climate. Humidity, heat, cold or even the wind can radically change the behavior of your glue, even if it is of professional quality as the super glue cyano glue Colle21.
🔍 Why are temperature and humidity so much?
Cyanoacrylate glues, such as those in the Colle21 range, react chemically to humidity present in air and materials. Here's what you need to know:
🌬️ Too low temperature :
-
The polymerization process slows down strongly.
-
The glue seems "inactive" or puts Over 60 seconds to take.
-
The risk of incomplete bonding increases.
🔥 Too high temperature :
-
Glue can become more fluid, even too liquid.
-
It can saturate porous surfaces, which weakens adhesion.
-
Drying is faster, but sometimes too brutal, causing whitening or tension.
💧 High humidity :
-
Accelerates the chemical reaction → taken ultra -fast.
-
Can create a "erasure" effect if the parts are poorly positioned.
-
Sometimes promotes the whitening (White Haze effect).
🌵 Air too dry :
-
Strongly slows down the catch.
-
Need an activator To compensate for the lack of humidity.
