Dow Polyurethanes strives to provide the information customers need to guide the selection of raw materials for their formulations and targeted applications. The information is tailored for formulators that use first principles as well as for those that only need the data required to balance the stoichiomctry of their systems. To improve our customer's experience we have developed searching and modeling tools that would allow formulators not only to quickly find the components they need hut also to predict the viscosity of basic prepolymers and quasi-prepolymers. We have also developed other modeling tools capable of predicting the curing time and viscosity buildup of coating systems in a broad range of seasonal temperatures. In this paper, we will demonstrate some of the capabilities that caa be used by formulators to select polyols based on first principles. Also discussed are the fundamentals behind the mechanistic models that predict prepolymer viscosity as a function of temperature, as well as curing profile of coating systems at several temperatures as a function of time,
