| Diofan® P 520 is a one-component, water-based dispersion of a polyvinylidene chloride (PVDC) copolymer. It is free of solvent traces, alkylphenol ethoxylates or any other toxic substances. Due to its low oxygen and water vapor permeabilities along with low water absorption, Diofan® P 520 is an outstanding protective copolymer used in a broad variety of formulations that are specific to end-use requirements. This material was developed to adhere on metal and to remain flexible when exposed to a broad range of end-use temperatures over time. This makes it an ideal binder for one-component, air drying, waterborne formulated paints and coatings where long-lasting protection of the substrate is targeted. Diofan® P 520 also provides excellent chemical resistance and flame-retardant properties. Typical applications are:
- Corrosion-resistant primers and coatings for industrial and heavy duty steel protection
- Automotive primers and underbody coatings
- Rust converter products
- Barrier and sealing coatings
- Flame-retardant coatings
- Fibers and textile coatings Applications: Coating Applications; Protective Coatings Features: Chemical Resistant; Flame Retardant; Good Adhesion; Low VOC; Moisture Barrier; Non-Toxic; Oxygen BarrierDiofan® P 520 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. Information provided by Solvay Specialty Polymers. |
