Overview
Product Overview
KORVANTO BENTO PAPER & DEINK™ is a premium-grade sodium bentonite specially processed for the pulp paper and recycled paper industries. Its unique thixotropic properties high surface area and excellent cation exchange capacity make it an effective retention aid drainage aid formation aid and deinking additive.
In paper manufacturing it improves fiber and filler retention enhances sheet formation optimizes drainage and contributes to better paper strength and surface quality. In deinking operations it assists in the removal of ink particles sticky contaminants fines and dissolved impurities from recycled paper pulp helping improve process efficiency and final paper quality.
Carefully processed to maintain low sand content and consistent particle size distribution KORVANTO BENTO PAPER & DEINK™ supports smoother machine operation reduced downtime and improved productivity in both virgin pulp and recycled fiber systems.
