FORMULATING PRINTABLE COATINGS VIA D-OPTIMALITY

A general method which enables one to use D-optimal design to help for mulate conventional printable coatings with a chosen set of ingredient s is given. The D-optimality criterion is briefly reviewed and is appl ied to the formulation process. Using simple polynomials, one builds m odels to approximate coating properties. Viable models can help formul ators in, developing and manufacturing coatings. The formulation proce ss of an actual coating is described in some detail to illustrate the procedure. Various merits and limitations of modeling with optimal des igns are also discussed.
