Application

Kollicoat SR is use as a controlled-release coating or as a matrix. Kollicoat polymers can be employed as film coatings (intelligent surfaces) with controlled-release agents, for instant-release or sustained-release applications. Kollicoat polymers can be used with all standard coating equipment and are cost-effective, delivering maximum quality in terms of function, stability, and appearance. This research grade product is intended for use in R&D and development only.

Analysis Note

appearance and solubility of a film must conform
