Fumed silica is a high-performance additive used to enhance the rheology and stability of adhesive and sealant systems. It acts as an effective thixotropic agent, preventing sagging and filler settling while providing controlled shear-thinning behavior for easy application. Its compatibility with different polymer systems, available in both hydrophilic and hydrophobic grades, allows optimized performance across formulations. Additionally, fumed silica reinforces the cured matrix, improving mechanical strength and overall durability, while maintaining viscosity stability during storage and after application.
