Which super glue glue is due to heat? Find the right solution for each burning application 🔥
Heat resistance is an essential criterion for many applications, whether it be home repairs, craft projects or industrial uses. Choosing the good super glue glue capable of supporting high temperatures is crucial to guarantee the sustainability and safety of your assemblies. Let us discover together the main types of glues that resist heat and their specific applications.
1. Cyanoacrylate glues (super glue): fast and resistant to moderate heat 💨🌡️
Often called "super glue", cyanoacrylate glues are renowned for their rapid intake and high adhesion. Although their resistance to heat varies considerably from one formulation to another, some are specifically designed for hot environments.
- How does it work? These glues polymerize in contact with the humidity of the air, creating a solid link in a few seconds.
- Supported temperatures: Standard cyanoacrylates generally hold up to 80 ° C. However, advanced versions, such as Colle21 super glue cyanoacrylate 21g, are formulated to offer much higher thermal resistance.
- The little plus glue21: There Colle21 super glue cyanoacrylate 21g is an excellent example of cyanoacrylate glue which goes far beyond the usual performance, capable of supporting temperatures going up to 150 ° C ! Ideal for repairs where heat is a factor, without reaching extremes.
- Typical applications: Ideal for model making, small repairs of electronic parts (where moderate heat can be present), jewelry elements, or fixings requiring intermediate thermal resistance.
- Compatible materials: Plastics (certain types), rubber, metals, wood, ceramic.
2. Epoxy glues: strength and sustainability in heat 💪🔥
Epoxy glues are bi-component adhesives (a resin and a hardener) which offer very high traction resistance and excellent durability, including heat.
- How does it work? The two components react chemically together to form a rigid and very resistant polymer.
- Supported temperatures: Most of the standard eposy resist temperatures from 80 ° C to 150 ° C. High temperature (HT) epoxies can support up to 200 ° C, or even 300 ° C for specialized formulations.
- Typical applications: Motor repairs, exhaust (for HT versions), structural, electronic assemblies, and demanding industrial applications.
- Compatible materials: Metals, glass, ceramic, wood, certain plastics.
3. High temperature silicone glues (HT): flexibility and sealing 🌡️💧
HT silicone glues are appreciated for their flexibility, their ability to create waterproof joints and their good heat resistance.
- How does it work? They polymerize in contact with the humidity of the air, forming a flexible and resistant joint.
- Supported temperatures: Generally from -50 ° C to +250 ° C, certain specific formulations can reach 300 ° C, or even 350 ° C in point.
- Typical applications: Seals for ovens, chimneys, household appliances (ovens, cooking plates), engines (Carter joints), and automobile applications.
- Compatible materials: Metals, glass, ceramic, rubber, certain plastics.
4. Super glue refractory glues and high temperature cements: for extremes 🔥🔥🔥
These glues are designed for applications requiring resistance to the most extreme temperatures.
- How does it work? Often based on silicates, alumina or cement, they harden by drying air and/or cooking.
- Supported temperatures: They can withstand temperatures ranging from 1000 ° C to more than 1500 ° C, or even 1700 ° C for the most efficient.
- Typical applications: Collage of refractory bricks, repair of chimneys, pottery ovens, sealing in wood stoves and incinerators, industrial applications in foundry.
- Compatible materials: Ceramic, brick, metals (iron, aluminum), refractory glass.
Choose the right glue glue: a question of temperature and application 🤔
To choose the glue that will keep heat, it is essential to consider the maximum temperature that assembly will have to support, but also mechanical stresses, humidity and materials to stick. For versatility and good thermal resistance up to 150 ° C, the Colle21 super glue cyanoacrylate 21g is positioned as an excellent choice for many daily applications and projects where moderate heat is at stake.
