Recommended Applications

Rid-O-Foam® A-4 is formulated for use in high gloss aqueous coating systems. It will not cause "fish eyes" or craters in most systems. Rid-O-Foam® A-4 will also not effect color acceptance or development. The product is also very effective in foam control in water-based metalworking fluids.

Recommended Use Levels

Rid-O-Foam® A-4 is normally used at a level ranging between 0.4 and 5 pounds per hundred gallons of latex paint. It is usually added in the pigment grind or during letdown, but can also be added into the paint before packaging. In latex polymerization, Rid-O-Foam® A-4 is incorporated at a level, starting at 0.01% based on total weight, during the polymerization reaction or during the stripping process. Foam control in a resin emulsion system is achieved at a level ranging between 0.01% to 1.0% based on total volume
