AI Overview
Defoaming agents for sizing are crucial additives designed to eliminate foam and prevent bubble formation in water-based adhesive systems (like PVA, starch, or acrylics) during paper or textile production. Key types include silicone-based for high-efficiency knockdown and fatty alcohol/polyether ester types for compatibility with paper white water.

What is a natural alternative to defoamer?
More natural defoamers are straight oils. For example, our old maple syrup used sunflower oil. I've seen other maple syrup makers use canola oil. But, the most common defoaming oils are seed oils, and that means PUFAs.Jun 6, 2025
