Dispersion Mechanism
Bis(triethoxysilylpropyl) disulfide acts as a molecular dispersant through:
Hydrolysis-generated silanols anchoring to filler surfaces (TiO₂, SiO₂)
Disulfide (-S-S-) bonds providing steric stabilization
Organic chains compatibilizing with resin matrices
Formulation Optimization
Parameter Standard Formulation Silane-Optimized
Viscosity (KU) 95 62
TiO₂ Loading 28% 35%
Hiding Power (m²/L) 14.5 18.2
Production Benefit
A Sherwin-Williams industrial coating plant achieved 22% reduction in milling time and 15% cost savings per batch through this technology.
