PMMA’s paintless applications
LX MMA’s paintless materials offer excellent weather resistance, coloring and anti-scratch properties, and can be used as final parts without going through the existing painting process, making them a good alternative for the purpose of cost reduction and environmental protection. In particular, these materials have been officially approved by global automotive OEMs (Hyundai/Kia, Renault, etc.) for their proven reliability.
