Technical Details & Test Data

Processing Guidelines: The recommended starting level of antifoam is 0.25% of the total weight of the system. In paint manufacturing, best results are usually obtained when half of the antifoam is added to the pigment before grinding to suppress the formation of foam, and the remainder added to the “let down” portion.

In adhesives, a starting addition of 0.5-2.0% of the weight of the latex solids is generally recommended.

Storage & Handling

Storage & Handling Information: This product exhibits excellent storage stability over a wide range of temperatures. However, for convenience in handling, storage at room temperature is suggested. For best results, mix well before using.
