Precipitated silica is a versatile functional additive used in adhesives and sealants to enhance rheology, reinforcement, and stability. It improves viscosity control, reduces settling of fillers, and provides better thixotropic behaviour for easy application without sagging. Additionally, it contributes to mechanical strength, surface finish, and durability of the cured system. With its high surface area and controlled structure, precipitated silica ensures consistent performance across a wide range of adhesive and sealant formulations.

Why Precipitated Silica is the preferred choice for adhesive & sealants formulations
Comprehensive range of Precipitated Silica grades for diverse industrial applications
Fine precipitated silica with controlled residue (<200 ppm on 500 mesh) for smooth dispersion and consistent performance in adhesive and sealant systems.
Ultra-fine precipitated silica with D50 of 5.2–5.8µm, providing enhanced rheology control, improved surface finish, and superior performance in demanding adhesive formulations.
Common questions about Precipitated Silica in adhesive & sealants applications
Find detailed answers about specifications, applications, and technical details.
It improves rheology, controls viscosity, enhances stability by preventing filler settling, and provides thixotropic anti-sag behaviour for better application performance.
Finer particle size provides better dispersion, smoother finish, and improved reinforcement. FMSIL 412 PLUS with D50 of 5.2–5.8µm delivers superior rheology and surface finish compared to coarser grades.
Yes. It provides thixotropic behaviour, meaning the material resists sagging at rest but flows easily during application — critical for vertical surface applications.
Yes. It reinforces the polymer system, improving durability, tensile strength, and elongation in the cured adhesive or sealant.
Yes, it is compatible with a wide range of adhesive and sealant systems including water-based, epoxy, PU, and silicone formulations.
FMSIL 200 is a fine grade with controlled mesh residue for smooth general-purpose performance, while FMSIL 412 PLUS is ultra-fine with D50 of 5.2–5.8µm for enhanced rheology and surface finish in demanding applications.
