Additive to lower foam formation and stability

详细技术说明

None

*Abstract

The present invention provides a foam destabilizing additive composition comprising a particulate polymer or emulsified liquid pre-polymer, water and a defoaming additive ester having the formula RCOOX wherein R and X are independently hydrocarbyl or substituted hydrocarbyl, and at least one of R and X contain at least two unsaturated carbon--carbon bonds. The foam destabilizing additive helps lower the amount of foam formed and its subsequent stability and allows for more rapid air release. The foam destabilizing additive is highly mobil and effective and, over time, is air oxidizes becoming an oligomer which would be less mobil and a more resin compatible component. Unlike mineral oil or silicone based defoamers, this foam destabilizing additive also can act as a coalescent aid in many latex resin based formulations. Additionally, this foam destabilizing additive can be made from natural or synthetic oils. The additive can potentially be used in water borne paints, coatings, inks, cutting fluids, weed and agricultural sprays, cleaning product compositions, and any application where foam suppression is desired. It can be added in the grind and/or in the letdown phase of film forming formula preparation.
