Metal bodies and plastic components such as bumpers typically require separate paint processes because of differences in heat resistance and curing conditions. PPG Low Temperature Cure coating technology combines coating material design and advanced curing mechanisms to broaden the processing window across metal and plastic substrates, helping enable more integrated body-and-bumper coating processes.

“This technology is about creating greater flexibility in how vehicles are painted,” said Haijiao Wang, PPG strategic marketing manager, topcoat, Asia Pacific, Automotive OEM Coatings, who presented the technology at the SURCAR event. “It streamlines paint operations, delivers consistent color across substrates and enables more integrated manufacturing processes.”

The platform offers two cure options: a stand-alone basecoat that cures at 110°C on its own, and a three-layer system that cures at 90°C together. This gives automakers flexibility to match the technology to different parts and production lines, expand the application of heat-sensitive substrates, and introduce low-temperature curing in phases according to individual production line requirements. The lower cure temperatures also provide a more energy-efficient alternative to standard higher-temperature processes that cure at 140°C.

PPG plans to begin line trials with leading automakers worldwide to further evaluate the technology across different paint processes, production conditions and vehicle platforms, accelerating its progression from technical development toward broader commercial application.
