IOTA FINE Precipitated Silica is a kind of superfine precipitated silicon dioxide (known as silica) made by special processing technology. It has excellent reinforcement and dispersion, many years of production practice shows that it can replace fully or partly of expensive fumed silica which has greatly reduce customers’ production cost.

Silica for defoamer
IOTA FINE-SIL517 silica particles can enhance the
defoaming effect of defoamer. In the defoaming agent, the antifoaming action
needs to be strengthened by silica particles. The silica particles were brought
to the air foam by silicone oil and water interface and enter the bubble film,
due to its hydrophobicity, and surfactant foaming liquid droplet contact angle
is greater than 90〫, thereby forcing the foaming liquid from the
solid surface by hydrophobic particles, causing rapid discharge, local bubble
rupture. Thus, due to the synergistic effect, the two components produced a
good defoaming effect. It is widely used in defoamer industry.
