Characterization of a phase separation of a coating composition

A computer-implemented method for providing a coating composition related prediction program, the method comprising:

• providing a database comprising associations of qualitative and/or quantitative characterizations of coating compositions in association with one or more parameters selected from the group comprising one or more of the components of the coating composition, relative and/or absolute amounts of one or more of the said components and/or manufacturing-process parameters of the coating composition;
• training a machine learning program on the associations of the coating composition characterizations with the one or more parameters in the database for providing a predictive model (M2, M3) having learned to correlate qualitative and/or quantitative characterizations of one or more coating composition with one or more of the parameters stored in association with the respective coating components and/or manufacturing-process parameters used for generating the coating composition;
• and
• providing a composition-quality-prediction program which comprises the predictive model (M2), the composition-quality-prediction program being configured for using the predictive model (M2) for predicting the properties of a coating composition from one or more input parameters selected from the group comprising one or more components of a coating composition, relative and/or absolute amounts of one or more of the said components and/or manufacturing-process parameters, the properties including the detection of a phase separation;
• and/or
• providing a composition-specification-prediction program which comprises the predictive model (M3), the composition-specification-prediction program being configured for using the predictive model (M3) for predicting, based on an input specifying at least desired storage stability characterization and optionally one or more additional parameters related to the desired coating composition, in particular components, process parameters and application parameter, and outputting one or more parameters related to a coating composition predicted to generate a coating composition having the input storage characterizations and optionally meeting the additional parameters as input, the one or more parameters being selected from the group comprising one or more components of the said coating composition, relative and/or absolute amounts of one or more of the said components and/or manufacturing-process parameters to be used for preparing the coating composition.
