Bentogel® in Solvent-Based Applications

Bentonite is the name given to clay minerals with high absorbency and was originally named after the mining deposit in Fort Benton, Wyoming, which was first developed for commercial purposes. Bentonites are geologically derived largely from volcanic sources, and the majority of currently exploited mineral deposits were formed through the hydrolysis of volcanic rocks or ash. For this reason, despite containing different mineral compositions, mineral deposits are found in almost every part of the world except Antarctica. With applications ranging from cosmetics and grease oils to food and paints, the primary purpose of bentonite in paint applications is to regulate the thixotropic properties of the paint.   The Bentogel series rheological additives manufactured by Yillong Chemical Group are produced using Na-bentonite (sodium) and Ca-bentonite (calcium) and processed through various steps. Bentonites extracted from minerals with similar mineral and morphological composition are first placed in water tanks at the facilities. Here, different substances are separated from the main structure and precipitated. Subsequently, purification is applied and the portion that will undergo reaction is separated. Up to this point, the mineral has a hydrophilic structure; following the reaction, it acquires a hydrophobic structure and is packaged after filtering, drying and grinding operations.

Bentogel BG Series Bentonites

Bentogel organic clays are used to impart thixotropy, anti-settling and anti-sag properties in solvent-based systems. Bentogel BG series products are particularly: • Effective anti-settling agents. This contributes to homogeneous pigment distribution. • Provide good spreadability and application thickness. • Provide appropriate viscosity control in solvent-based systems during manufacturing, storage and application. • Resistant to changes in thixotropic properties with temperature. • Easy to use; requires no special method or equipment. You can see the basic properties of Bentogel BG series products in the graph below. When these products are used at appropriate solvent/polarity values, they impart different properties to solvent-based paint and ink systems.

Contributions in Paint

• Rheological properties of the entire system are improved. • Prevents pigment settling and, when applied to vertical surfaces, prevents sagging. Ensures uniform application thickness. • By improving spreadability, it prevents brush marks that may occur. • Increases water resistance of the system. • Improves storage stability even at high temperatures. • Since it is used in small quantities in formulations, its effect on the final product gloss is very low. • Contributions in ink. • Prevents pigment settling. • Contributes to color distribution. • Contributes to achieving the desired film thickness. • Reduces fog/haze in application, improves tackiness control.
