Surface Additives are special chemical formulations applied to the outer layer of paper or board to improve how the sheet looks, prints, and performs during converting. They do not change the core structure of the paper; instead, they modify the surface so the final product becomes smoother, stronger, and ready for high-quality printing and packaging applications. Modern paper mills rely on advanced Surface Additives Chemicals to meet customer demands for sharp printing, vibrant colours, and a premium finish suitable for commercial use. Understanding Surface Additives in Simple Words Surface Additives are chemicals that paper mills apply at the size press or coater to improve the top layer of the sheet. Think of them as the “finishing touch” that ensures the paper surface behaves correctly during printing. Without proper Surface Additives, paper may absorb too much ink, appear dull, or develop issues such as feathering, smudging, or uneven print coverage. Surface Additives help crea...

Improving paper quality is not about one single solution—it’s about how different wet-end processes work in harmony. Two of the most important elements in this process are Paper Machine Defoamer and Paper Machine Deaeration . When used together, they help mills achieve smoother operation, better formation, stronger sheets, and fewer defects. Why Foam and Air Are Big Problems in Papermaking Foam creates surface disturbances, overflows, and coating issues. Hidden air inside the pulp causes drainage delays, vacuum overload, and internal sheet defects. To produce consistent, high-quality paper, both problems must be controlled at the same time. That’s where defoaming and deaeration work as a combined system—not separate tools. Role of Paper Machine Defoamer A Paper Machine Defoamer targets visible surface foam. It: Breaks bubbles quickly by lowering surface tension Prevents re-foaming in high-turbulence zones Reduces pinholes, streaks, and formation problems Stabilizes the w...
