Bentogel BG3 is a rheological additive, specifically an organoclay, used to improve the properties of various materials, particularly in coatings, inks, and other applications. It’s made from modified bentonite clay (both Na-bentonite and Ca-bentonite) and is known for its ability to enhance thixotropy, prevent settling, and control viscosity. It’s effective in both solvent-based and water-based systems.
Benefits:
- Rheological modification: Bentogel BG3 alters the flow properties of materials, providing desirable characteristics like thixotropy (shear-thinning behavior) and sag resistance.
- Anti-settling: It helps prevent pigments and other solid particles from settling out of suspension, maintaining a uniform product.
- Viscosity control: It can be used to adjust and stabilize the viscosity of formulations, ensuring proper application and performance.
- Wide solvent polarity range: It can be used in a variety of solvents, from low to high polarity.
- Good dispersion: It disperses well in the medium it’s added to, ensuring even distribution of the additive.
Properties:
- Coatings: Improving sag resistance, film thickness, and leveling in paints and other coatings.
- Inks: Providing proper viscosity and preventing pigment settling in printing inks.
- Personal care products: Used as a thickening agent in various formulations, according to R.E. Carroll, Inc.
- Other applications: Used in adhesives, sealants, and other formulations where rheological control is desired,
