“Nitro-Hydro-Flame” treatment technology for polymer surfaces
By Stefano Mancinelli, sales & process mgr. EsseCI s.r.l. Some substrates, such as plastics, have inert and non-porous chemical surfaces that make them non-receptive to the affixing of various materials, such as printing inks, adhesives and coatings. Surface treatment increases the surface tension (wettability) of the material to prepare it for subsequent applications, … [Read more...] about “Nitro-Hydro-Flame” treatment technology for polymer surfaces
