Dow Chemical has introduced a diamond wire ingot squaring coolant that improves photovoltaic (PV) wafer manufacturing efficiency while also improving the sustainability of the production process.

ENLIGHTTM DC-8300 Coolant, which will be officially unveiled at the 26th European Photovoltaic Solar Energy Conference (26th EU PVSEC), is the latest innovation from Dow that can help improve performance and/or lower the total system costs of PV applications.

Next-generation diamond wire saws are designed to reduce overall PV manufacturing costs by using a higher cut speed and fixed abrasive technology instead of loose abrasive slurry for cutting. ENLIGHTTM DC-8300 Coolant is designed to address common challenges associated with diamond wire cutting processes. The product offers:

+ High Cutting Precision and Efficiency: Because of its excellent suspension and dispersion capability, as well as other attributes, the percentage of bricks with high thickness variables (TV) can be reduced with ENLIGHT TM DC-8300 Coolant. In addition, ENLIGHTTM DC-8300 Coolant can sustain multiple rounds of cutting, thus helping to improve customers' production efficiency.

+ Easy Cleaning: With its remarkable properties, ENLIGHTTM DC-8300 Coolant helps to greatly reduce stickiness issues on the guide roller and on the machine interior parts. It also reduces the silicon sedimentation in the tank.

+ Good Environmental Profile: Water-based ENLIGHT DC-8300 Coolant offers a better environmental profile than glycol-based coolants in the marketplace. In addition, it enables easier silicon powder separation, thus offering higher potential for waste silicon recycling.

"In trials customers have observed ENLIGHTTM DC-8300 Coolant can significantly reduce ingot defects, is easy to handle and offers a clean ingot cutting process for their plant. By improving their cutting precision and efficiency, our product also helps customers optimize their overall manufacturing cost," says Lensey Chen, Strategic Marketing Manager, The Dow Chemical Company.

"This new coolant can help accelerate the adoption of diamond wire cutting, helping the industry progress in its goal to reduce cost per watt."

Driven by its company-wide focus on delivering sustainable solutions to address some of the world's most crucial challenges - including the need for clean energy - Dow continues to invest in products and manufacturing capabilities to help PV manufacturers to improve efficiency and lower their total system costs.
