Abstract
Official abstract text for this publication.
A foam control agent and method of controlling foam for metal working fluids by use of a foam control agent, wherein the agent comprises at least a branched alcohol.
First claim
Opening claim text (preview).
The invention claimed is: 1. A method of controlling foam for metal working fluids comprising the step of adding a foam control agent to the metal working fluid, wherein the agent comprises 2-butyl-1-octanol, or 2-propylheptanol. 2. The method of claim 1 , wherein at least one other foam control agent or hydrophobic material is used. 3. The method of claim 1 , wherein the metal working fluid, when combined with the foam control agent, is transparent.
