Apr 4, 2002When plasticizer was incorporated in the coating formulations, heat-humidity curing effectively improved the acid resistance of the coated films at all plasticizer levels investigated.

Dec 1, 2001The heat-humidity curing condition suppressed evaporation of the plasticizer, resulting in higher plasticizer levels remaining in the films, as compared to the heat-only curing

How do plasticizers affect film forming temperatures?
For example, plasticizers in coating formulations soften the polymer spheres to allow for coalescence at lower temperatures (Lippold et al., 1990). Both plasticizer type and plasticizer concentration have been shown to influence minimum film forming temperatures (Flosser et al., 2000).
What is the history of coating in the pharmaceutical industry?
Coating processes in the pharmaceutical industry date back to the mid 1800s, when sugar-coated tablets were first introduced (Porter, 2012). Based on technology from the candy industry, multiple layers of sugar were applied by ladling aqueous sugar solutions onto substrates as they rotated in a drum.
Why do dispersed polymer systems have a minimum film forming temperature?
In addition to the particle size of the polymer spheres, temperature plays an important role in particle coalescence and film formation. In contrast to polymer solutions, dispersed polymer systems require the polymer spheres to deform and fuse together to form the film. Thus, these systems exhibit a minimum film forming temperature (MFFT).
