Celotech Ruico Silicone-Based Defoamer Features
Our silicone defoamers are developed to deliver fast, long-lasting foam control with excellent stability for your project options.
Can achieve rapid and long-lasting defoaming action at very low dosage levels, especially for large-volume industrial processes.
High temperature resistant due to the silicon-oxygen structure, good for high-temperature dyeing and resin synthesis applications.
Chemically inert and can maintain good performance in a wide pH range, suitable for acidic wastewater treatment or high-alkaline cleaning formulations.
With broad system compatibility, suitable for emulsions, solutions or modified grades, widely used in paints, coatings and inks.
Less VOC or health risks during and after application, helpful to healthier indoor air quality, safer building materials and strict environmental regulations.
Extremely low surface tension to cut down the existing foam and its persistent formation effectively, improve workability, efficiency and quality.
Celotech Ruico Silicone-Based Defoamer Uses
We designed different kinds of silicone-based defoamers for paints, industrial coatings, and printing ink with high-quality performance.
Celotech Ruico silicone-based defoamer is specially formulated for thick paint, providing long-lasting foam suppression and breaking in water-based coating systems, ideal for high-viscosity latex paints used in roller application.
In flexographic and gravure printing, our silicone-silicone defoamers can rapidly suppress foam introduced by high-speed ink circulation and doctor blade action. It is helpful for the stability in ink transfer, clean print effect, and consistent color density.
Celotech Ruico polyether siloxane defoamer can help avoid bubbles in the processes of self-leveling, can make the coating spread evenly without defects, improving the surface flatness and gloss.
In immersion, flow coating, and spray coating processes, high fluid movement and air contact lead to persistent foam. Our silicone-based coating defoamers provides fast knockdown and long-lasting control, maintain stable operation, and coating quality.
Silicone-Based Defoamers Packaging and Storage
Packaging: available in 25kg/bucket or 180kg/bucket sizes, and customized packaging is supported.
Storage: keep the defoamers away from direct sunlight and unopened at a temperature of 5°C to 35°C. The validity period is 12 months after the manufacturing date.

FAQ About Silicone-Based Defoamer:
Silicone-based defoamers work better in controlling foam but are suitable for some sensitive formulations. While non-silicone defoamers have better compatibility with most systems, the foam control ability is relatively weaker.
It depends. Silicone defoaming agents have better performance than mineral oil ones, while mineral oil defoamers are more cost-effective and more compatible in specific systems and have no silicone contamination.
The reference amount for our silicone-based defoamers is 0.1-1.0% of the total formulation. The specific dosage should be adjusted according to actual conditions.
Yes, our silicone defoamers are compatible with many water-based PUD systems if the proper grade is selected. We recommend you conduct a test to confirm compatibility and avoid surface defects in your formulation first.
Yes, split addition like part during dispersion and part during let-down or final adjustment, is often more recommended for better long-lasting foam control.
