Etherified amino resins are used in conjunction with alkyds, polyesters, ep
oxy or acrylic resins in coating formulation. They are formed from the reac
tion between formaldehyde and compounds containing NH, groups, for example,
amide, amine or imide groups. Control of this reaction is important in ord
er to obtain the appropriate mixture targeted for the intended use and, as
a consequence, the development of analytical procedures able to describe th
e different species present in the final resin mixtures is necessary. The u
se of high-performance liquid chromatography, coupled with electrospray ion
isation or atmospheric pressure chemical ionisation mass spectrometry, prov
ed to be efficient in the characterisation of n-butylated melamine-formalde
hyde resins, The same analytical approach was also applied to describe the
first steps in the synthesis of i-butylated urea-formaldehyde resins.
