Diofan® B 203 is a PVDC water-based dispersion with outstanding impermeability to gases and moisture. It is particularly recommended for coatings on plastic films. Key Attributes: Moisture Barrier; Oxygen Barrier Applications: Barrier Coatings; Coating Applications Agency Ratings: EC 1907/2006 (REACH); EU No 10/2011; FDA 21 CFR 175.320; FDA 21 CFR 177.1630 DELIVERY AND STORAGE - Diofan® B 203 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. PROCESSING - DRYING - Diofan® B 203 can be processed with different coating techniques, including reverse gravure roll and air knife coating systems. - When coated on plastic films, Diofan® B 203 should be formulated with wax and silica in order to improve the blocking and slip properties of the finished coating. - Diofan® coatings requires adequate drying conditions, since in general higher temperatures will contribute to 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.
