Effects of Low Temperatures on Cyanoacrylate Adhesives. Ethyl-2 Cyanoacrylate adhesive, commonly referred to as “super glue,” or “CA” are essential in manufacturing and engineering due to their quick bonding capabilities and high-strength adhesion. However, the performance of these adhesives can be significantly affected by external factors, particularly temperature. Colder weather presents unique challenges that impact the properties and application of these adhesives. For businesses that depend on consistent adhesion in cold environments, understanding the temperature effects of cyanoacrylate glue is vital for maintaining product quality and operational efficiency.
CA glue bonds quickly through a chemical reaction with moisture in the air. However, lower temperatures create several challenges:
Cold air contains less moisture, which slows down the polymerization process necessary for bonding. This results in extended curing times, potentially reducing efficiency in high-throughput manufacturing.
At lower temperatures, some adhesives can become brittle, undermining the bond’s strength, and limiting their reliability in demanding applications. Alternatives such as rubber toughened grades can mitigate this risk, providing a more flexible bond, especially when used on dissimilar substrates that may expand and contract at different rates.

Improper storage can result in thickening or crystallization of the adhesive, which further compromises the performance of super glue.
Understanding these properties of cyanoacrylate glue is essential for achieving optimal results, particularly in industries where precision and durability are critical.
In manufacturing and engineering, lower temperatures can significantly influence the production process and end-use performance. For example:
Assembly lines in unheated facilities may face delays due to longer curing times.
Businesses must evaluate environmental changes and supply chain to ensure that the challenges of winter production and usage are minimised.
To address the challenges associated with temperature effects on cyanoacrylate glue, consider implementing the following strategies:
Store adhesives at room temperature in airtight containers to prevent changes in viscosity or crystallization. If this is not possible then make sure the adhesive is at room temperature. This also applies to adhesives in cold storage, make sure to bring the adhesive back up to room temperature before application.
Warm substrates and work environments facilitate faster curing and stronger bonds. Just-in-time (JIT) deliveries may have parts that have been exposed to longer periods of cold such as being stowed on the back of a lorry overnight. Ensure the substrate temperature is at a reasonable level before bonding.
Increase ambient humidity in cold environments to expedite the curing process, which can be as straightforward as placing a bowl of water nearby.
One of the most effective advancements for ensuring consistent results in cold environments is the application of activators. These specialized products are utilized on substrates either prior to or following the adhesive to accelerate curing and facilitate controlled bond formation. See our range of Cyanoacrylate Activators here.
By enhancing the polymerization process, activators mitigate the delays associated with low temperatures and reduced humidity.
They enable organizations to achieve a precise and repeatable cure, which is essential for quality assurance in manufacturing and engineering applications.
Reduced curing times contribute to more efficient production schedules, even in colder conditions.
In challenging environments, pairing your cyanoacrylate adhesive with an activator can optimize super glue performance and ensure reliable bonding, regardless of temperature conditions.
Low temperatures can pose significant challenges to the performance of cyanoacrylate adhesives, but with the right strategies, these challenges are manageable. By understanding cyanoacrylate glue properties and preparing for the temperature effects on CA glue, businesses can maintain efficiency and reliability even in the harshest conditions.
