| Coatings of Diofan® A 063 PVDC water-based dispersion exhibit good adhesion on Corona treated polyolefin and PET films. The coatings are tack free. This grade is in particular recommended for the coating of extruded - laminated PE, and as an extrusion primer for PE on various substrates. Applications: Coating Applications Features: Moisture Barrier; Oxygen BarrierDiofan® A 063 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 063 can be processed with different coating techniques, including reverse gravure roll and air knife coating systems.
- When coated on plastic films, Diofan® A 063 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. |
