Super Glue (Cyanoacrylate Adhesive) is a fast-setting, one-part adhesive that polymerises in the presence of moisture to form a very strong bond between substrates.
Key Characteristics:
-
One-Component System: No mixing required – the adhesive cures on contact with traces of moisture (even humidity in the air).
-
Rapid Cure Time: Initial handling strength in 5–30 seconds; fully cured in minutes.
-
Low Viscosity: Thin formulations wick into hairline gaps; thicker “gel” grades resist running and can fill small voids.
-
Brittle Bond: Creates a rigid, glass-like joint that excels in shear strength but can crack under impact or flex.
-
Shelf Stability: Typically sold in sealed tubes or ampoules; once opened, remaining adhesive will gradually thicken and may need refrigeration to extend usability.
Common Uses:
-
Household Repairs: Bonding broken ceramics, plastics, metal fittings, rubber trims and more.
-
Hobby & Model-Making: Securing small parts in scale models, crafts and jewellery work.
-
Medical Applications: Medical-grade grades (ethyl or methyl cyanoacrylate) used for skin closure in minor wounds (often branded as “tissue adhesive”).
-
Industrial Assembly: Fast fixturing of components in electronics, automotive trim, and small-parts manufacturing.
-
DIY Projects: Quick repairs on tools, fittings, eyeglass arms, and other non-structural joins.
