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 coatings Substrates can be concrete, cement, wood, gypsum, paper, fiberboard, fabrics and others. Key Attributes: Flame Retardant; Low to No Water Absorption; Moisture Barrier; Non-Toxic; Oil Resistant; Oxygen Barrier Applications: Barrier Coatings; Coating Applications Agency Ratings: EC 1907/2006 (REACH); EU No 10/2011 DELIVERY AND STORAGE - Diofan® 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 25°C (41 °F and 77°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. FOOD AND DRUG LEGISLATIONS - Some agency ratings are listed on page 1. Necessary certification will be provided upon request. ISO CERTIFICATION - The implemented management system for the production, internal transfer and delivery, design and development of Diofan® vinylidene chloride copolymers (PVDC) produced in Tavaux has been assessed and found to meet the requirements of ISO 9001: 2008, ISO 14001: 2004 and OHSAS 18001: 2007.
