DIOFAN® A 736 is a PVDC water-based dispersion recommended for use as a flexible underlayer for barrier coating on rigid PVC or PVC/ PE film, to be covered with DIOFAN® 193 D as top coat. The film structure is used for blister application in pharmaceutical packaging. Applications: Barrier Coatings; Coating Applications Features: Good Flexibility; Moisture Barrier; Oxygen BarrierDiofan® A 736 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 30°C (41 °F and 86°F) to avoid degradation. - IBC should be protected from sunlight exposure. PROCESSING - DRYING - Diofan® A 736 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.
