IOTA XPT-118 is used as a fast-emulsified defoamer in pigment-containing systems. Due to its good compatibility, it can be added at any stage of the paint. It can be dispersed in an aqueous solution or an organic solvent. The use of polymer emulsions to avoid the generation of bubbles, the addition of polyvinyl alcohol aqueous solution and emulsion polymerization of monomer degassing can achieve good results.
