What is Laser Cure Technology?

Unlike traditional thermal ovens, laser curing harnesses near-infrared (IR) light to initiate crosslinking, the chemical reaction that transforms powder particles into a durable protective finish. This innovative process offers: 

Rapid curing and cooling in minutes
Targeted heating is suitable for both conventional and heat-sensitive substrates
Meaningful reductions in energy consumption and waste
Faster, more precise finishing compared to traditional IR systems

Industry-First Capabilities

PPG announced the installation of a state-of-the-art pilot finishing line that features IPG’s PhotoniCURE™ laser curing system at its powder manufacturing and technical facility in Strongsville, Ohio, and a laboratory system for research feasibility studies at the PPG Coatings Innovation Center near Pittsburgh.

Key Benefits

Energy Efficiency and Sustainability:
Finishing is one of the most energy-intensive manufacturing processes. Laser curing offers a more energy-efficient alternative that supports sustainability goals by reducing carbon footprints and heat waste.

Speed and Performance:
Accelerates throughput with faster curing times and enhanced finishing line speeds, enabling manufacturers to meet growing demand without compromising performance.

Versatility:
Laser curing enables new possibilities for innovative product designs and applications. It is compatible with both standard powder chemistries and those optimized for laser curing.
