Thermoplastic Acrylic Resin For Rubber Primer SE2574
Thermoplastic acrylic resin is synthetized by different acrylic
monomers, its main advantages are the stability of light and its
resistance to hydrolysis. In general, during synthesis,
thermoplastic resins use a high content of methyl methacrylate in
their polymerization backbone chain to provide excellent hardness
and external durability, while improving the wettability of
pigments and/or providing cross-linking or self-crosslinking
capabilities.
