Hydrafine 90W is designed for use in single coated, high carbonate coatings where a higher level of kaolin is desired and blade pressure control is critical. With a unique particle size distribution that balances plate size for rheological control, Hydrafine 90W can deliver gloss, print gloss and laser etching properties of Hydragloss 90 in applications where the high solids needed to leverage the efficiency of our ultrafine plates cannot be easily achieved.
