In the coatings sector, stability, viscosity control, and proper pigment suspension are essential factors to ensure optimal performance, both in the laboratory and in production.
To address these needs, the Bentogel range—developed from modified bentonites—has become a reliable and efficient option for formulators working with both solvent-based and water-based systems.
We present three essential rheological additives for the coatings industry:
Bentogel BG3, BG4, and BG8L, each adapted to different polarity ranges and system requirements.
Bentogel BG3: stable performance in low- and medium-polarity solvent-based paints
Bentogel BG3 is designed to deliver high gelling efficiency in solvent-based systems with low and medium polarity. Thanks to its ability to improve thixotropy and suspension, this rheological additive helps prevent pigment sedimentation, ensuring a homogeneous and stable mixture.
Key Benefits
- High gelling efficiency
- Excellent thixotropic behavior
- Stable suspension and sedimentation control
- Contributes to film reinforcement in organic systems
Applications
- Solvent-based acrylic paints
- Anti-corrosion paints
- Road-marking paints
- Lubricants
- Adhesives
- Inks
Its versatility makes it suitable for formulations requiring stability across different temperatures and consistent rheological control.
Bentogel BG4: rheological control for medium- and high-polarity solvent-based systems
Bentogel BG4 is a rheological additive designed for medium- and high-polarity systems. It offers stable and reproducible behavior, even in complex formulations, with the advantage of not requiring polar activators or pre-gel preparation, reducing processing time and simplifying plant incorporation.
Key Benefits
- Easy dispersion without polar activators
- Stable, reproducible thixotropic consistency
- Excellent sag resistance
- Can be added at the end to adjust viscosity without affecting the formulation
Applications
- Acrylic paints
- Anti-corrosion paints
- Wood coatings
- Varnishes
- Sealants
- Lubricants
- Inks
Its light color and transparency help maintain the final appearance of the coating without affecting tone or brightness.
Bentogel BG8L: the ideal option for water-based paints and coatings
Bentogel BG8L is specially designed for aqueous systems, offering uniform and stable rheology. Its thickening ability makes it possible to optimize final viscosity without compromising transparency or coating quality.
Key Benefits
- Strong thickening capacity in water-based systems
- Homogeneous and stable rheology
- Good suspension without affecting clarity
- Compatible with a broad range of aqueous formulations
Applications
- Water-based paints and coatings
- Adhesives and sealants
- Asphalt sheets and asphalt emulsions
- Mastics
- Gypsum and cement systems
- Mortars and grouts
