Description
Advanced 2-Component Superglue
Würth Klebfix 2C Superglue is a transparent, flexible two-component cyanoacrylate adhesive designed for high-strength bonding, gap filling, and universal use across many materials. Its unique formulation combines the instant bonding speed of cyanoacrylate with the gap-filling and structural strength of a 2C system.
Superior Gap Filling and Precision
Unlike standard superglues, Klebfix 2C can fill adhesive gaps up to 6 mm with very low shrinkage. This makes it ideal for repairs, uneven joints, and applications where standard thin adhesives cannot perform. The gel-like consistency prevents running, enabling controlled application on vertical and overhead surfaces.
Durabiliy and Strength
After curing, the adhesive achieves an impressive tensile strength of 4–7 N/mm² and a load-bearing capacity of up to 75 kg/cm². It maintains performance across a temperature range of -40°C to +80°C, with excellent resistance to petrol and diesel, making it highly suitable for demanding industrial, automotive, and mechanical applications.
Versatility and Practical Application
Supplied in a 10 g syringe or double cartridge system, Klebfix 2C is easy to handle without the need for additional equipment (in syringe format). The fine static mixer tips allow precise application directly to the bonding surface, ensuring reliable results even in delicate repair work.
Special Applications
- Plastic bonding (including PMMA) - transparent bonds without visible joints.
- Repairs with unknown or variable gaps - reliable curing even in thick adhesive layers.
- Food processing plants - suitable for repairs in environments with hygiene and safety requirements.
- Automotive and industrial repairs - fuel- and impact-resistant bonding.
Limitations
- Not suitable for use in pure oxygen or highly oxygenated environments.
- Avoid application on heavily oxidising or heavily chlorinated substrates.
- Permanent UV resistance not guaranteed - direct sunlight exposure may cause yellowing or cracks over time.

Application Instructions
Ideal for bonding parts with different or unknown adhesive gaps (up to 6 mm) or for applications where excess adhesive needs to cure completely. The high gap filling capacity and high initial adhesion on most surfaces make the system a perfect repair product. The gel consistency prevents running even on vertical surfaces. Suitable for bonding in food processing plants
