    Kollicoat® IR is one of our true multitalents for instant release

    As instant release film former, Kollicoat® IR combines exceptional coating quality with simple, robust processing. As wet binder, it combines powerful binding with no peroxides at all. And all those characteristics also make it a great pore former for sustained release formulations.

    Kollicoat® IR is a robust yet flexible polyvinyl alcohol/polyethylene glycol graft copolymer. This water-soluble film-forming agent is ideal for manufacturing instant-release coatings for solid dosage forms – and for applications such as binding, pore forming and drug layering. Kollicoat® IR’s high pigment-loading capacity makes the spraying process easier and faster. And because dispersions made using Kollicoat® IR have low viscosity despite their high solids content, coating can be significantly accelerated. The result? Highly reliable, cost-effective processes that produce first-class results every time.

    Why choose Kollicoat® IR?
    Highly flexible film thanks to integrated plasticizer
    High pigment-loading capacity
    Easy to formulate and process
    For rapid, cost-efficient coating

    Kollicoat® IR - Powerful binder. No peroxide formation.

    Kollicoat® IR is not only a perfect solution for instant release film-coating – it can be also used for various other applications. As wet binder, it provides high binding efficiency. Due to its low viscosity values in aqueous solutions, easy processing in a vast process parameter range is assured. Furthermore, Kollicoat®IR does not contain or form any peroxides along the life time of a pharmaceutical product.

    Why choose Kollicoat IR as wet binder?
    Binding performance comparable to PVP, superior to HPMC
    Easy processing due to low viscosity in solution
    No peroxide formation at any time
