DIOFAN® 193 D is a PVDC water-based dispersion recommended for use as a functional topcoat over DIOFAN® A736 coated PVC or PVC/PE film structures used for blister applications in pharmaceutical packaging. Key Attributes: Moisture Barrier; Oxygen Barrier Applications: Barrier Coatings; Coating Applications Agency Ratings: DMF 8738; EC 1907/2006 (REACH); EU No 10/2011; FDA 21 CFR 175.300; FDA 21 CFR 175.320; FDA 21 CFR 176.170; FDA 21 CFR 176.180; FDA 21 CFR 177.1630 DELIVERY AND STORAGE - Diofan® 193 D is delivered in bulk or in Intermediate Bulk Containers (IBC). Bulk supplied latex should be stored in reservoirs made of suitable stainless steel, HDPE, rigid PVC or glass fiber-reinforced polyester. - Contact of anionic Diofan® dispersion with metals like iron, zinc, aluminum and copper as well as alloys such as brass and bronze must be avoided. - Keep the vessels tightly closed to prevent drying through evaporation. Store the product ideally between 5°C and 25°C (41 °F and 77°F) to avoid degradation. - IBC should be protected from sunlight exposure. PROCESSING - DRYING - Diofan® 193 D can be processed with different coating techniques, including reverse gravure roll and air knife coating systems. - Diofan® coatings require adequate drying conditions, since, in general, higher temperatures will result in better barrier properties. ISO CERTIFICATION - The implemented management system for the production, internal transfer and delivery, design and development of Diofan® vinylidene chloride copolymers (PVDC) produced in Tavaux has been assessed and found to meet the requirements of ISO 9001: 2008, ISO 14001: 2004 and OHSAS 18001: 2007.
