Superliimaa

Superliimaa is a family of fast-acting cyanoacrylate adhesives used to bond a variety of materials. It cures rapidly when exposed to moisture in air or on the bonded surfaces, forming a strong, hard polymer that holds the pieces together. The adhesive comes in different viscosities, from thin liquids that flow easily to gels that stay in place for gap filling.

Composition and curing

The main active component is an alkyl cyanoacrylate. Cure occurs through an anionic polymerization reaction activated by trace moisture, which is why the bond often forms within seconds. Temperature and surface moisture influence the setting speed: higher humidity and warmer temperatures generally accelerate curing. Thicker formulations or gel variants are suitable for vertical applications or gaps, while low-viscosity types suit fine or tight joints. Some products are designed to be non-drip or to offer a short open time for repositioning.

Applications and limitations

Superliimaa bonds many non-porous materials such as metal, glass, ceramics, wood, and many plastics. It is commonly used for quick repairs, small assemblies, and hobby or crafts. It may bond skin and many materials instantly and can cause heat buildup with large volumes. It is less effective on oily or smooth polyolefins like polyethylene and polypropylene unless surfaces are prepared or primers are used. It is generally not suitable for structural or load-bearing joints that require high mechanical strength over time.

Safety and handling

The adhesive can cause skin and eye irritation and fumes can be drying or irritating in poorly ventilated areas. Avoid contact with skin and eyes; use in a well-ventilated space. If skin bonds occur, do not force separation; soak in warm soapy water or use appropriate removers as directed. Keep away from children and heat sources.

Storage and disposal

Store tightly closed in a cool, dry place. Shelf life varies by product but is typically 12–36 months when unopened. Do not expose to moisture or heat. Dispose of in accordance with local regulations for household chemicals.
