Dosage Guideline:
The product is typically added directly and may be incorporated at any stage of the production process. In
most cases, it is recommended to add half during the pigment/filler dispersion/milling phase and the remaining
half during the final emulsion formulation stage. Depending on foam severity, the typical dosage ranges from
0.1% to 0.5% of the total formulation weight; the optimal dosage and injection point should be determined
through laboratory testing.

FAQ
Defoamer BF-201L is a high-performance foam control agent designed for various aqueous systems. It is especially suitable for low-gloss paints, paper coatings, textured coatings, and low, medium, and high PVC formulations.
The typical dosage of BF-201L is 0.1% to 0.5% of the total formulation weight, depending on foam severity. The optimal dosage should be confirmed through laboratory testing.
BF-201L can be added directly at different stages of the production process. In most cases, it is recommended to add half during the pigment or filler dispersion stage and the remaining half during the final emulsion formulation stage.
BF-201L helps control foam effectively, supports smoother coating production, reduces foam-related surface defects, and provides good suitability for water-based paint and coating systems.
BF-201L should be stored in sealed packaging at 5-30°C. It should be kept dry, protected from freezing, and stored away from direct sunlight. If layering occurs during storage, re-stirring before use is recommended.
