Frequently Asked Questions

Common questions about FMSIL & FUSYL Series for Powder Coatings in paints & coatings applications

FMSIL (precipitated silica) is primarily used for reactive matting, gloss control, and cost-effective flow improvement in standard industrial and decorative powder coatings. FUSYL (fumed silica) provides superior flow, fluidization, and sprayability in fine powder, tribostatic, and super-durable HAA systems requiring consistent long-term storage stability.

FMSIL 412 PLUS delivers superior reactive matting efficiency through its optimized surface area and pore structure, producing a more uniform matt surface appearance and consistent gloss control across the cured film versus conventional precipitated silica grades, while maintaining equivalent mechanical performance.

FUSYL T74 (silane-modified high surface area fumed silica) provides more consistent and efficient powder flow, improved sprayability, and more uniform surface appearance in super-durable HAA systems versus conventional fumed silica — critical for high-performance outdoor architectural coatings requiring both long-term durability and consistent appearance.

Typical dosage range is 0.1–3.0% by weight, depending on the powder type, formulation, and application requirements. FMSIL grades typically require slightly higher loading for matting applications, while FUSYL grades deliver effective flow at lower concentrations due to their higher surface area.

Yes — FMSIL and FUSYL can be incorporated at multiple stages: directly in the premix hopper, during melt-mixing/chipping, or as post-pulverization additions. Post-addition is preferred when maximum surface coating efficiency is required for flow and sprayability improvement.
