LF 20 is a medium viscosity, low-odour alkoxy-ethyl cyanoacrylate adhesive. LF 20 is a low bloom product specially formulated for cosmetically critical applications to eliminate whitening/chlorosis of bonded joints.

The low-odour characteristic improves user comfort and is compatible with more sensitive plastics.
