In the construction and manufacturing sectors, sealants are indispensable for creating durable, weather-resistant, and aesthetically pleasing joints. The performance of a sealant hinges significantly on its rheological properties, particularly its ability to resist sagging and maintain shape after application. Organic bentonite rheological additives are key ingredients that empower sealant manufacturers to achieve these critical performance characteristics.

The Importance of Rheology in Sealants

A sealant must be viscous enough to adhere to surfaces without dripping or slumping when applied, especially on vertical or overhead applications. This characteristic, known as anti-sagging or sag resistance, is a direct outcome of a sealant's rheological profile. Thixotropic additives, like organic bentonite, are widely employed to provide this necessary control. They enable the sealant to become more fluid under the stress of application, allowing for easy extrusion and tooling, and then rapidly build viscosity once the stress is removed, holding the sealant in place.

Organic Bentonite: A Key Formulation Component

Our high-quality organic bentonite, a leading product in the rheological additive category (CAS No. 68911-87-5), is an excellent choice for sealant manufacturers. Designed for effectiveness in low to medium polarity solvent systems, it offers:

  • Superior Anti-Sagging Properties: Crucial for maintaining the integrity of applied sealants, particularly in demanding construction environments.
  • Controlled Viscosity Build-up: Ensures the sealant has the right consistency for both application and long-term performance.
  • Enhanced Suspension of Fillers: Prevents heavy fillers from settling, ensuring a homogeneous and stable sealant product.
  • Improved Workability: Facilitates easier application and better tooling for professional finishes.
