Halamid has no surfactant activity and does not produce foam. If you prefer that surfaces treated with Halamid are more visible, a foam booster such as SLS (sodium lauryl sulfate), SLES (sodium laureth sulfate) can be added to Halamid in a concentration of 1:2000 (calculated on the Halamid solution used). Instead a pH-neutral cleaner containing SLES can be used.
