In this study, core-shell self-crosslinking latexes comprising different levels of
copolymerized perfluorethyl groups in the shell layer of latex particles were prepared
by the emulsion polymerization of 2,2,2-trifluoroethyl methacrylate, methyl
methacrylate, butyl acrylate, and methacrylic acid as main monomers. The effect of
crosslinking (inter-particle self-crosslinking and intra-particle crosslinking) was
evaluated with the aim to spare the fluorinated monomer consumption while
maintaining the desired water-resistant coating properties. For achieving the interparticle
self-crosslinking, diacetone acrylamide was copolymerized into the shell layer
of latex particles to provide sites for the subsequent reaction with adipic acid
dihydrazide. The intra-particle crosslinking of latex particles was introduced by
copolymerizing allylmethacrylate during the synthesis. The results showed that water
sensitivity of coating films was reduced most notably by the level of crosslinking, while
the effect of fluorine content in particle shell composition was minor only.
