“A Model-based Solvent Selection and Design Methodology for Coating Formulations”
Abstract
It is known that solvents account for one third of the cost in coating formulations and are extremely important in order to deliver the active ingredient (pigment and binder) of the formulation.
They are vital in conferring the final aesthetic and functional properties of the coating [1]. Therefore, the selection of the solvent mixture is a critical step in coating formulation design. The generic Computer-Aided Product Design (CAPD) methodology [2] has been adapted to specifically design organic coating formulations.
The presentation highlights a model-based framework for the design of solvents for these coatings. It is developed in order to aid a formulation chemist to quickly arrive at a solvent mixture with the desired physico-chemical and environmental, health and safety (EH&S) properties.
Such a model-based methodology is useful as it can reduce the search space for the solvent mixture. The applicability of this framework has been tested via a casestudy on solvent mixture design for an acrylic-based organic coating.
