TAAC Program

WHAT IS TAAC?

TAAC (pronounced 'tack') is an acronym for Thermodynamic Analysis of Aqueous Coating. As its name implies, the model utilizes thermodynamic heat and mass transfer equations to accurately characterize the environmental conditions inside a coating pan during a steady state film coating process.

The purpose of TAAC is twofold. First, it allows a user to investigate the interrelationships between process variables. For example, the model can be used to determine how a change in spray rate will affect the exhaust air temperature.

Second, TAAC provides the user with a measure of film drying rate which, once calculated for a given set of conditions, can be used to reproduce a desired quality under an entirely different set of conditions. It is this second feature of TAAC which is generally of greater interest to the user since it makes parameter variation studies and optimization possible.

An electronic copy or CD of the TAAC program along with a complete reprint of the Pharmaceutical Technology magazine article featuring the full mathematical and thermodynamic development of the model can be obtained by contacting Thomas Engineering's marketing department.
