Kalfren

Kalfren, distributed by Washington Mills, is a potassium aluminum fluoride that, when used as an active filler, increases lubricating properties in organic-bonded abrasives. Kalfren improves the durability and performance of organic-bonded abrasives by reducing the temperature in the contact zone between the workpiece and cut-off or grinding wheel, and can be used alone or in combination with other active fillers.
