Abstract

Polystyrene nano/microparticles obtained from post-consumer expanded polystyrene waste (WPS) were dissolved in toluene and incorporated into a commercial-grade automotive primer. The use of WPS situates the developed product within current sustainability and circular economy concepts. The main objective of this study was to develop an automotive primer containing 2 and 4 wt.% of nano/microparticles. For this purpose, WPS particles were dissolved in toluene and added to the primer, which was formulated with various compatibilizers and plasticizers. The resulting P03 primer exhibited chemical, rheological, mechanical, and morphological properties comparable to those of standard commercial primers, demonstrating that the addition of WPS-derived nano/microparticles does not compromise performance. This approach provides a promising recycling route for WPS, avoids secondary waste generation, and aligns with the principles of sustainable development and the circular economy.
