Defoamers

OS‑431 Defoamer is a non-silicone defoamer that is particularly well suited to controlling foam in aqueous dry film developing solutions and stripping solutions.  OS‑431 is unique because it is water soluble at the concentrations at which it is normally used for defoaming solutions.  This means that unlike many other defoamers, no oily film will be left on parts processed in solutions defoamed with OS‑431.  Furthermore, any OS‑431 that might be carried over on the parts into subsequent rinse tanks will completely dissolve in the rinse water, thereby preventing oily films from accumulating on the surface of the rinse water.  OS‑431 is used at low concentrations.  Therefore, it is economical to use.

OS-429 is a non silicone defoamer specifically formulated for controlling foam in dry film developing baths and in stripping baths for dry films and alkaline inks. It is also useful for controlling foam in post cleaning systems after solder reflow. OS-429 provides long lasting foam control at low concentrations. Because of its low use concentration, OS-429 is inexpensive to use.

BB330 is a blend of polyoxyethylene and polyoxypropylene copolymers that is used to control foam over a wide pH range (2-12) for both photo-resist developing and stripping operations. BB330 additions should be diluted with process solution before adding to the sump. This is to ensure adequate dispersion of the de-foamer in solution.

BB-200 is a blend of polyglycol acid ester and a hydrophobic silica in a hydro-treated heavy naphthenic distillate that is used to control foam over a wide pH range (2-12) for both photo-resist developing and stripping operations. BB-200 additions should be diluted with process solution before adding to the sump. This is to ensure adequate dispersion of the defoamer in solution.
