Paper Grade Bentonite Powder

Bentonite is used in the paper industry as a retention agent and as a coating agent to improve the performance of paper products. Bentonite is a type of clay mineral that has a high cation exchange capacity, which makes it useful for various applications, including papermaking.

As a retention agent, bentonite is added to paper pulp to improve its ability to retain fine particles, such as filler materials, dyes, and pigments. This improves the quality of the paper and also reduces the amount of raw materials needed to produce a given paper grade.

Bentonite is also used as a coating agent in the production of coated papers. The coating process involves applying a layer of bentonite to the paper surface to improve its printing properties, such as ink absorbency, print sharpness, and color reproduction. Bentonite coatings can also improve the paper's resistance to water, oil, and grease, making it more durable and suitable for various applications.
