Edwal LFN Wetting Agent is a low foam, liquid wetting agent. Just two drops of super-low-foaming, non-ionic LFN in a pint of developer will prevent air bubbles and floating dust particles from causing pinholes. Just two drops per pint of water for use as a film rinse will prevent water spots. Hanging film will drain evenly and completely.
An LFN final rinse solution for RC (resin coated) prints which are to be air dried by hanging will promote even drying and cut drying time by about half. LFN foams much less than other wetting agents so bubbles disappear in seconds.
