Theoretical Coat Assessment Whitepaper

Coating particle encapsulation is a critical factor in controlled release and delivery systems, but the complexities of coat thickness, particle size, and density can make the process challenging. This whitepaper delves into the theoretical aspects of coat assessment, offering valuable insights into how size, size distribution, coat thickness, and density impact particle encapsulation. With this information, you can make informed decisions in your formulation processes, ensuring that your products meet the necessary performance and quality standards.

What You Will Learn:

• Understanding Coat Volume and Weight Fractions:
  Learn how to calculate and assess coat volume fractions for spherical particles and understand how to translate these into more tangible coat weight fractions.
• Influence of Particle Size and Shape on Encapsulation:
  Discover how particle size and shape impact coat thickness and weight, and how this influences the encapsulation process, particularly for small particle sizes that pose unique challenges.
• Practical Considerations in Coating Processes:
  Explore the practical implications of coat thickness, particle distribution, and the dynamics of fluid bed coating, including factors like attrition, agglomeration, and accretion that can affect coat uniformity.
