In the industrial production of waterborne coatings, inks, and other products, issues such as poor substrate wetting, craters, and residual foam often act as "stumbling blocks" that affect product quality.A New Solution for Wetting and Defoaming in Waterborne Systems This unique structure endows it with the ability to simultaneously achieve wetting, defoaming, and anti-cratering effects.
From a physical perspective, IOTA-4100 appears as a light yellow transparent liquid with an active ingredient content of up to 100%, eliminating the need for additional dilution and allowing for maximum efficacy. At 25°C, its refractive index is stable at 1.440-1.450, and its viscosity is controlled between 20-60cp, ensuring good fluidity and ease of addition and dispersion. Its most prominent feature is its surface tension, which can be reduced to below 23mN/m at a concentration of 0.1%, effectively lowering the surface tension of waterborne systems and easily achieving full coverage of difficult-to-wet substrates.
As a specialized silicone surfactant for waterborne systems, the non-foaming property of IOTA-4100 stands out, addressing the common problem of "defoaming causing foaming" in traditional additives. It is particularly suitable for processes with high requirements for non-foaming, such as spraying and high-speed roller coating. With an addition rate of only 0.1%-1.0%, it can simultaneously achieve excellent substrate wetting, leveling, anti-cratering, and defoaming effects, making it applicable to various mainstream systems such as waterborne polyurethane, acrylic, and epoxy. It is a highly cost-effective comprehensive additive.
