Rising energy costs significantly have impacted industrial coatings companies. The emergence of strong global competition has createdadditional pricing and competitive pressures within the market. Additionally, more stringent environmental regulations are shrinking the already tight margins of industrial coaters, making production expansion difficult. The choice of curing technology, therefore, has a significant impact on all of key factors, including product quality, operating costs, and efficiency of the production line.
Traditional solvent based curing technologies emit VOC pollutants. These pollutants must must be abated, requiring large, capital intensive thermal drying systems and exposing coaters to volatile energy prices. And while UV based curing technologies address the issue of VOCs, they also can limit production speeds and prove ineffective in reaching the penetration depths of thicker coatings.
Electron beam curing is energy efficient and delivers a complete, consistent, high quality cure that penetrates through the thickest of coating layers. Furthermore, electron beam curing uses 100% solid coating formulations, which do not emit VOCs as part of the curing process. However, the electron beam curing approach traditionally has not been a viable alternative due to its large size, complex integration and maintenance, and high capital expense.
