BASF's new Larolux System Reduces Costs for Three-Dimensional Part Coating

Innovative UV curing process is fast, efficient and reduces energy needs

MOUNT OLIVE, N.J., April 27, 2004 -- BASF has introduced the Larolux coating curing system that utilizes lower energy ultraviolet (UV) light under a carbon dioxide atmosphere to quickly cure coatings placed on three-dimensional metal, plastic or wood objects.

"This new technology provides manufacturers with important cost- cutting benefits that can improve their products as well as the efficiency of their operations," said Werner Peter, Business Director for BASF's Performance Chemicals business in North America. "The Larolux system can cut curing times for coated three-dimensional parts, and reduce VOCs and energy costs. It also reduces or eliminates many problems that part manufacturers face including 'heat- effect,' and coating viscosity issues that present formulating challenges."

The Larolux system employs coatings made with BASF's UV curing agents and UV light in a curing oven that contains a carbon dioxide atmosphere. When the oxygen content in the gas surrounding the parts is low, the UV dose can be reduced so simpler, less expensive lamps can be used, and simple reflectors can illuminate three-dimensional objects. Under these conditions, thorough curing is independent of the parts' geometry. As a result, three-dimensional parts that were difficult to cure using traditional UV air curing techniques can be cured using the Larolux process.

Ultra Violet Systems, a division of UV Technology, Ltd., Houston, Texas, is the first UV light equipment manufacturer in the United States that has worked with BASF to construct UV curing ovens that are equipped with low-energy lamps designed to cure using carbon dioxide.

Allied PhotoChemical(R) Inc., Kimball, Mich., a coatings formulator in North America, is working with BASF to formulate coating systems specifically designed for the Larolux process.
