| 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. Applications: Barrier Coatings; Coating Applications Features: Moisture Barrier; Oxygen BarrierDiofan® 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 30°C (41 °F and 86°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. Information provided by Solvay Specialty Polymers. |
