Frequently Asked Questions

Common questions about Precipitated Silica in adhesive & sealants applications

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.
