Common questions about Precipitated & Fumed Silica in pigments applications
FMSIL (precipitated silica) has controlled particle size and balanced surface area — suitable for general pigment extension and paste stabilisation. FUSYL (fumed silica) has extremely fine particle size and very high surface area — preferred for high-performance pigment systems where maximum anti-settling, rheology control, and low-dosage effectiveness are required.
FUSYL forms a weak three-dimensional hydrogen-bonded network within pigment powders and pastes that controls pigment mobility, prevents hard settling, and stabilises pigment distribution — ensuring pastes remain processable and redispersible after long storage periods.
FMSIL is typically used at 1–5% and FUSYL at 0.5–2% by weight of the total pigment/extender system. Due to FUSYL's very high surface area, significant rheology and anti-settling effects are achieved at very low dosages, making it highly cost-effective.
Yes, both FMSIL and FUSYL are chemically inert and non-reactive with pigment chemistry. They do not impart colour, alter shade, or interfere with the optical behaviour of the pigment system, making them universally compatible with organic and inorganic pigment systems.
Stable dispersion behaviour, controlled pigment mobility, improved paste stability, reduced formulation variability, predictable pigment performance, and consistent batch-to-batch reproducibility in pigment powders and concentrates.
