It s not Rocket Science to Reach Higher Coating Efficiency. PlasACRYL T20 makes it possible. EUDRAGIT Technical Formulation GMP Proof of Advanced Products Support 1 2 3 4 5 6 Development Services Concept Drug Delivery

for use with EUDRAGIT aqueous-based acrylic polymers coating system additive PlasACRYL T20 is a 20% emulsion of anti-tacking agent and plasticizer that eases the preparation of a robust spray suspension. It offers several advantages in preparation and decreases the amount of spray suspension without a negative effect on the functionality. PlasACRYL T20 is commonly used in conjunction with acrylic polymer coating systems for tablet, pellet and crystal coatings. Applications Easy-to-use coating system additive plasticizer anti-tacking agent Enteric coating systems Sustained-release systems Features Eliminates the need for talc Will not settle in spray lines Prevents nozzle clogging No high shear mixing needed Widely accepted ingredients Aids in reducing tablet to tablet cohesion Benefits Reduced preparation time and steps About 30% less spray suspension and coating time Decreased overall production costs
