Paper Coating Defoamer: Ensuring Defect-Free Paper Surfaces

(Back to all Pulp & Paper Applications)

In the paper manufacturing chain, paper coating is a critical process enhancing printability, gloss, smoothness, and barrier functions crucial for packaging, graphic arts, and specialty papers. However, achieving a flawless coated surface is often challenged by foam generated during coating preparation and application. Even small amounts of foam can lead to costly defects like pinholes, fisheyes, and craters, and reduce production efficiency.

Utilizing an effective paper coating defoamer, a key coating additive, is essential. INVINO offers specialized foam control agents engineered for various paper coating systems.

Our paper coating defoamers are designed to deliver significant value:

• Enhancing Paper Coating Quality: Effectively eliminates defects like pinholes, fisheyes, and craters caused by foam, ensuring a smooth, uniform coating surface essential for high-quality printing and appearance.
• Reducing Production Downtime: Minimizes issues like coating skips or web breaks caused by foam build-up in coating applicators (e.g., blade, roll). Reduces cleaning cycles related to foam deposits, leading to higher operational efficiency.
• Optimizing Coating Material Usage: Prevents foam from causing inaccurate metering or overflows, reducing the waste of valuable coating components like binders and pigments.
• Excellent Compatibility & Stability: Our defoamers are compatible with common coating binders (latex, starch) and additives, maintaining stability throughout the coating kitchen and application process.

INVINO, a key player and potential factory source in the China defoamer additive market, offers a portfolio of specialized defoamers for coatings tailored for the paper coating industry.

• Tailored Products: We provide highly compatible modified silicones and effective non-silicone options designed to minimize defects in water based and other coating systems.
• Expert Guidance: We assist papermakers and coating formulators in selecting the optimal paper coating defoamer, offering support comparable in value to resources like the byk defoamer selection guide. We help balance performance needs with cost considerations.
• Reliable Quality: Ensuring consistent antifoaming agent performance batch after batch.

Achieving a high-quality, defect-free coated paper surface requires effective foam control throughout the paper coating process. Selecting the right paper coating defoamer—balancing efficiency, compatibility, and minimal impact on final properties—is critical. INVINO provides advanced antifoam technology and expertise to help you produce superior coated paper products.
