Rheology plays a vital role in determining the flow behavior, ease of application, and long-term stability of solvent-based paints. Achieving optimal rheology ensures smooth application, uniform coverage, and durability. Rheology refers to the flow and deformation behavior of materials.
In solvent-based paints, rheology determines:
Ease of Application: Ensures smooth flow during brushing, rolling, or spraying.
Film Build and Sag Resistance: Prevents dripping or uneven coatings on vertical surfaces.
Pigment Suspension: Keeps pigments and fillers evenly distributed, ensuring consistent color and texture.
The Role of CAB-O-SIL® Fumed Silica in Solvent-Based Paints
CAB-O-SIL® TS-720, a hydrophobic fumed silica, is engineered to address these challenges and provide superior rheological performance in solvent-based systems.
1. Thickening Efficiency
CAB-O-SIL® TS-720 increases viscosity efficiently, ensuring a stable and uniform film build without excessive material usage.
2. Shear-Thinning Behavior
The additive adjusts viscosity under shear, allowing easy application during brushing or spraying while maintaining structure post-application to prevent sagging.
3. Anti-Sagging Properties
CAB-O-SIL® TS-720 reinforces the paint’s ability to stay intact on vertical surfaces, eliminating issues like dripping or uneven thickness.
4. Pigment and Filler Stabilization
By preventing settling, CAB-O-SIL® TS-720 maintains the uniform distribution of pigments and fillers, ensuring consistent color and finish.
5. Hydrophobic Properties
The PDMS surface treatment of CAB-O-SIL® TS-720 reduces moisture absorption, making it particularly effective in solvent-based systems where moisture can cause defects.
Applications of CAB-O-SIL® TS-720 Fumed Silica
