audioprint® L-1 is the universal, radiation-curing one-component varnish for surface finishing of hard earmolds and custom shells (e.g. audioprint® GR-1, GR-10 and INR-1). Its optimized flow and adhesion properties produce a homogeneous, high-gloss surface on the earpiece that is easy to clean and scratch-resistant. A novel additive system adapted to the acoustic application ensures maximum protection against yellowing, even after prolonged exposure to UV light. Now available as audioprint® L-1 | MSI, to prevent biofilm adhesion and facilitate cleaning of earmolds.
