cyanoacrylate
LowTechnical/Specialised
Definition
Meaning
A fast-acting, strong-bonding adhesive that works by polymerising on contact with moisture.
Any of a class of synthetic adhesives based on cyanoacrylate esters; commonly known as superglue. Used medically as a tissue adhesive, industrially for bonding non-porous materials, and domestically for quick repairs.
Linguistics
Semantic Notes
The term is almost exclusively used in technical or scientific contexts. In everyday speech, brand names or 'superglue' are preferred. The core semantic field is polymer chemistry and industrial adhesives.
Dialectal Variation
British vs American Usage
Differences
No significant differences in meaning or usage. Spelling is identical. The generic term is less common than brand names (e.g., 'Super Glue', 'Krazy Glue' in the US) in everyday speech in both regions.
Connotations
Connotes a specific, powerful chemical adhesive in both varieties. In medical contexts (e.g., 'butyl cyanoacrylate'), it connotes a surgical tool.
Frequency
Equally low frequency in both dialects due to its technical nature. The simplified term 'superglue' is far more frequent in casual registers.

Context Usage
Business
In industrial supply catalogues and technical specifications for manufacturing.
Academic
In chemistry, materials science, and medical journals discussing tissue adhesives or polymerisation.
Everyday
Rare. Replaced by 'superglue'. Might be heard in hardware stores or among hobbyists.
Technical
Primary context. Precise term for a class of chemical compounds in engineering, forensics (fingerprint lifting), and surgery.
Examples
By Part of Speech
verb
British English
- The technician will cyanoacrylate the components for a permanent fix.
- I managed to cyanoacrylate my fingers together.
American English
- The modelmaker cyanoacrylated the tiny parts in place.
- Be careful not to cyanoacrylate the lid shut.
adjective
British English
- The cyanoacrylate adhesive set before I could adjust the part.
- A cyanoacrylate-based sealant was specified.
American English
- Use a cyanoacrylate gel for vertical surfaces.

Examples
By CEFR Level
- This strong glue is called superglue.
- Be careful with superglue – it sticks skin instantly.
- I need a strong adhesive to fix this plastic.
- For bonding non-porous materials like metal or plastic, a cyanoacrylate adhesive is often the most effective solution.
- The model was assembled using a special instant-bonding glue.
- The forensic team employed cyanoacrylate fuming to develop latent fingerprints on the glass surface.
- Butyl cyanoacrylate has revolutionized certain minimally invasive surgical procedures as a tissue adhesive.
Learning
Memory Aids
Mnemonic
Think: 'CYAN' (a blue-green colour) + 'O' + 'ACRYLATE' (a type of plastic). Imagine a blue bottle of super-strong acrylic glue.
Conceptual Metaphor
BOND AS INSTANT FUSION (It metaphorically 'welds' or 'fuses' surfaces instantly, like magic).
Watch out
Common Pitfalls
Translation Traps (for Russian speakers)
- Avoid translating it as 'цианоакрилат' in everyday conversation; it's overly technical. Use 'суперклей' (superklei).
- Do not confuse with 'клей момент' (a brand name for various adhesives); cyanoacrylate is a specific chemical type.
Common Mistakes
- Mispronunciation: /saɪˈæn.oʊ.../ instead of /ˌsaɪ.ə.noʊ.../.
- Using 'cyanoacrylate' as a countable noun (e.g., 'a cyanoacrylate') – it's usually non-count.
- Confusing it with epoxy or other multi-part adhesives.

FAQ
Frequently Asked Questions
Yes, 'superglue' is the common name for adhesives whose main ingredient is ethyl cyanoacrylate or a similar compound.
No. It works best on smooth, non-porous materials (plastic, metal, glass). It bonds poorly to porous surfaces like wood or paper and can damage some plastics and foams.
It polymerises (solidifies) in the presence of the weak base found in the moisture on skin and in the air, creating strong chains that bind surfaces.
Carefully use acetone (nail polish remover), special debonding solvents, or gently roll/peel it off after soaking in warm, soapy water. Never pull bonded skin apart forcefully.
