Diofan® A 602 is a water based dispersion of a polyvinylidene chloride copolymer. It is free of solvent traces, alkylphenol ethoxylates or any other toxic substances.
It features strong barrier properties to water vapor and very low water absorption. Diofan® A 602 also offers very good resistance to oil and benzene. Due to a very low MFFT, this waterborne binder can be applied at low temperature as a flexible and tack free film.
Diofan® A 602, as chlorinated based latex, combines also fire retardant properties. End uses are for example:
- Barrier and sealing coatings
- Flame resistant coatings
- Fiber and textile coatingsSubstrates can be concrete, cement, wood, gypsum, paper, fiberboard, fabrics and others. Applications: Barrier Coatings; Coating Applications Features: Flame Retardant; Low to No Water Absorption; Moisture Barrier; Non-Toxic; Oil Resistant; Oxygen BarrierDiofan® A 602 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 602 can be processed with different coating techniques, including reverse gravure roll and air knife coating systems.
- When coated on plastic films, Diofan® A 602 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. |
