KOLLICOAT® IR
PVA-PEG graft copolymer A breakthrough in instant release film coating, Kollicoat IR is an innovative new coating polymer derived from BASF’s extensive polymer research. They are basically polyvinyl alcohol-polyethylene glycol graft copolymers slightly modified to render different application values. All the grades are in powder form and give an extremely flexible film without addition of any plasticizer and offer pH independent release. Kollicoat IR grades are white to faintly yellow free-flowing powder that is very rapidly soluble in acidic, neutral and alkaline aqueous media. Such aqueous solutions have low viscosity.
