Kollicoat IR coating systems – Technical aspects
Come in and learn more about
by using our innovative product line Kollicoat IR coating systems.
Easy and safe handling
Dust-free and free-flowing granules simplify your processes and make them safe.
The unique manufacturing process for Kollicoat IR coating systems results in granules with uniform particles and a narrow particle size distribution. All seven grades have an almost identical particle size and density.
You can prepare the suspension and have it ready for starting the coating process within approximately 15 minutes. Low shear mixing is recommended for preparing the suspension.
Cost and time savings
The low viscosity of Kollicoat IR coating systems in water enables high solids levels and leads to short process times. Solids levels as high as 25% to 30% are recommended in coating suspensions prepared with Kollicoat IR coating systems because viscosities are below 200 mPa•s. In contrast to Kollicoat IR coating systems, PVA- and HPCM-based reference products are recommended to be handled at less than 20% and 15%, respectively.
Additional cost savings can be achieved by using Kollicoat IR coating systems through:
High-quality film coating
The excellent product properties enable an easy scale up. The process parameter chart visualizes the robustness of a process by increasing or decreasing of product temperature at a certain spray process time. The dark green color in the process parameter chart indicates a large parameter range that will result in optimum film properties. As to the large parameter range the process is very robust. The film coating trials were performed with Kollicoat IR Brilliant Blue in a Vector LDCS
coating machine at 2kg batch size.
The very low viscosity as well as excellent wetting and adhesion to the tablet surface ensure that even your fine engravings are uniformly coated. No logo bridging occurs. The scanning electron micrograph belows shows a tablet coated with Kollicoat IR White II at a coating level of 5 mg/cm2.
Kollicoat IR leads to extremely flexible films. They are significantly more flexible than those made of a comparable PVA- or HPMC-based product. The high flexibility of the films ensures that they do not crack on the tablets. See for yourself the excellent flexibility of Kollicoat IR films and click here!
