PMA
Functionally modified monomer with low hydroxyl content; it exhibits excellent pigment dispersibility and is suitable for use as a surface or primer coating for plastics, metals, and vacuum-plated substrates. It can be overcoated with PU or UV clear varnishes, offering superior interlayer adhesion. It is also suitable for use in screen printing inks.
A-7440 resin is synthesized through the copolymerization of (meth)acrylate monomers and functional monomers, utilizing PMA as the solvent. This resin exhibits excellent compatibility with CAB and NC, and the resulting paint films are characterized by strong adhesion, superior weather resistance, and other desirable properties.
