With a smaller molecule size the methyl cyanoacrylates have better affinity to metals and can sometimes offer better resistance to solvents. The methyl grades of cyanoacrylate would often be specified for bonding plastic to metal or rubber to metal applications. The basic monomer is a very thin (low viscosity) liquid typically around 3-5 mPa-s. These methyl cyanoacrylate adhesives can be used to ‘wick-in’ to pre-assembled items such as for locking small adjustment screws or for increasing the strength of two press-fitted components.
