Introduction to Silicone Deaerators

Silicone deaerators are specialized compounds used to remove trapped air from inks, coatings, and other industrial formulations. The trapped air can cause defects in printed materials, impacting quality and performance.

Mechanism of Action for Silicone Deaerators

Silicone deaerators function primarily by reducing the surface tension of air bubbles, facilitating their rise to the surface and subsequent removal. Their efficacy is quantified by the rate of bubble elimination, measured in seconds, and the reduction in ink's apparent viscosity.

• The efficiency of deaeration is often measured via the degassing rate, with effective deaerators removing up to 95% of air within 15 minutes.
• Viscosity reduction by up to 30% can enhance ink flow and consistency, thus improving print quality.

Impact on Ink Quality

Silicone deaerators offer substantial improvements in ink quality. By minimizing defects such as pinholes, blisters, and inconsistent color density, they ensure a smoother finish and more durable prints.

• The surface finish can see an improvement in gloss ratings from 70 gloss units to over 90 gloss units.
• Color consistency index can improve by up to 40%, as measured on a spectrophotometer.

Topwin Company Solutions

Topwin's range of silicone deaerators includes products specifically formulated for various inks and applications, such as UV-curable and solvent-based inks. The Topwin X-200 series, for example, effectively addresses air entrapment issues while enhancing compatibility with different substrates.

• Topwin X-200: Reduces entrapped air by 90% and enhances drying time by 20%.
• Topwin ZX-150: Designed for high-speed printing, achieving a 25% improvement in ink gloss.
