CESA BROCHURE - Clariant

AntifogFood packaging and horticultural filmsused with water-containing productsoften fog over on their inner surfacedue to the condensation of tiny dropletsof moisture. Droplets are particularlyundesirable in greenhouse films, wheregood light transmission is essential forcrop growth.CESA-nofog additive masterbatcheseliminate the problem by lowering thesurface tension of the water droplets,causing them to merge and form acontinuous transparent Half-time layer that charge maintainsdecay (sec.) electrical conductivity sometimesthe clarity of the 50 film.
