Diofan® A 299 is a PVDC latex recommended for coatings requiring the best balance of barrier and low sealing temperature properties. Applications: Coating Applications Features: Moisture Barrier; Oxygen BarrierDiofan® A 299 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. PROCESSING - DRYING - Diofan® A 299 can be processed with different coating techniques, including reverse gravure roll and air knife coating systems. - When coated on plastic films, Diofan® A 299 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.
