Self–drying Acrylic Resin For Rubber Primer SE2554
Thermoplastic acrylic resin SE2554 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.
