Application Spotlight
See how our coating defoamers help customers control the foam issues in real coating productions.
A coating manufacturer has air entrapped during mixing and application of a waterborne 2K waterproof coating system. Celotech Ruico recommended the defoamer agent RT8086 and worked with the customer to rebalance the overall formulation. By adjusting surfactant and rheology to match the system, the customer achieved:
- Visible and internal foam reduced significantly during high-shear mixing and rolling stages
- Decreased viscosity anomalies and stabilized the performance during production
- Smooth surface finish after curing and ensured the water resistance performance of the two-component waterproof coating.
A customer has the problem of foam regeneration when producing a waterborne anti-corrosion coating. The foam issues caused uneven coating surfaces after application. Our team provided the defoaming and antifoaming solution, which helped the coating client get satisfied results:
- Diminished continuous foam effectively during high-shear mixing and airless spray processing
- Eliminated pinholes and craters, maintaining a more level and uniform coating surface
- Restored the film’s compactness and intercoat adhesion for long-term anti-corrosion performance

How to Optimize Defoamer Performance
In addition to choosing the correct grade for your coating system, we also consider your usage and will guide you to optimize defoamer performance.
Addition Strategy:
In complex coating systems, split addition can help you control foam better. For some types of defoaming agent, you can add part during pigment dispersion or grinding to control process foam. Additionally, you can add some during let-down or mixing to help manage application-related bubbles. We will collaborate with you to optimize the addition points based on your formulation.
Dispersion and Storage Control:
Proper dispersion is important to ensure the defoamer consistency. You should always stir or shake the defoaming product thoroughly before use. A simple action can help you achieve uniform distribution of defoamer, especially after long-term storage or under low temperatures.
Dosage Optimization:
The recommended dosage typically ranges from 0.05% to 1.0% of total formulation, and we will help you adjust the suitable amount in your system. When changing emulsions and other additives, you must conduct compatibility testing first.
